Further details on proposed Illinois toll hike; Illinois tolls rather low

Posted on by

The Chicago Tribune reports today that the Illinois State Toll Highway Authority wants to raise toll rates in order to raise money for several new projects, including a reconstruction of I-90 (the Jane Addams), adding an interchange between I-294 and I-57 (one of the few places in the US where two interstates do not have an interchange), extending the Elgin-O’Hare, and undertaking several studies for possible new roads (extending Route 53, the Illiana Expressway).

But there is more to this story. While the Authority wants money to undertake these projects, there is another defense for raising rates: Illinois toll rates are lower than other states.

The council urged that tolls on the existing tollway system be raised to levels “consistent with national averages” to generate revenue for the EOWB [Elgin-O’Hare West Bypass]. Currently, Illinois Tollway users pay the equivalent of 3 cents per mile, while the national average is 7 cents per mile, officials say. Using that model could result in a systemwide doubling of the current rate, to 80 cents from 40 cents for passenger vehicles using I-PASS, and to $1.60 from 80 cents for cash customers…

The report also said tolls on the EOWB itself should be “consistent with the level of other new toll projects nationwide,” or about 20 cents a mile. This suggests that tolls on the new highway could be as much as seven times the current rate, or $2.80 for passenger vehicles using I-PASS and $5.60 for cash customers…

In addition, the council’s report recommends that future toll increases be indexed to inflation. The last time the tollway hiked car tolls was 2005, but that was the cash rate. Cars with I-PASS pay the same rate as they did in 1983, the tollway says…
The report also urges consideration of so-called congestion pricing strategies, in which vehicles pay higher tolls during peak hours or for express lanes; extending the tollway’s bond maturity term up to 40 years; and giving further study to tolling adjacent freeways. That could mean imposing tolls on I-290.

I’m guessing Chicago area residents will not like this as it makes driving more expensive (particularly with the price of gas) and there will general grumbling about how the tolls were supposed to disappear at some point. But, roads have to be paid for somehow and whether motorists pay through tolls or gas taxes, they will pay for the privilege of using roads. If anything, perhaps Chicago area residents should be surprised that tolls have stayed so low when other states have raised them. Since we can probably assume that the cost of road building has gone up like everything else, it sounds like tolls should increase.

If there is a larger issue to be concerned about, we could ask about the planning undertaken by the state. A road like the Illiana Expressway has been discussed for decades and waiting this long to undergo a major study and then go through with the construction will cost more now than it would have years ago. The Elgin-O’Hare has been a running joke for a while. Additionally, it would be interesting to see how close or far planners were in estimating the number of vehicles that would use the highways each day. The early expressways in the area, I-294 and I-290 are two examples, have seen much more traffic than was initially anticipated, driving up costs. Overall, more foresight could have saved money.

The weekend of “Carmageddon” in Los Angeles

Posted on by

Local highway construction doesn’t typically garner national attention. But there has been plenty of news for weeks about a key highway closing in Los Angeles:

Interstate 405, a freeway normally so clogged that locals like to joke that its name is shorthand for “traffic that moves no faster than 4 or 5 miles an hour,” is closing for 53 hours for a major construction project.

As crews worked feverishly to get the freeway open in time for Monday morning’s rush-hour, residents have been making plans for weeks to stay off local roads, lest they trigger what officials dubbed “Carmageddon.”

Such an event could back up vehicles from the 405 to surface streets and other freeways, causing a domino effect that could paralyze much of the city.

With warnings having been broadcast through television, radio, social media and flashing freeway signs as far away as San Francisco, much of the city’s nearly 4 million residents appear ready to stay off the roads.

As I have seen multiple stories about this, several thoughts came to mind:

1. It is a 53 hour closure, not the end of the world. This has been overhyped. People will survive.

2. Shouldn’t planners be lauded more for doing the work over a summer weekend? The preparation for the whole project actually sounds pretty good.

3. People don’t often think about roads until they are a problem. This is a good example of that.

4. Even though it may have been overhyped, this is still a legitimate social problem, particularly for emergency vehicles and other important highway users. This seems to be more common with highway construction: a long, well-publicized campaign to make sure that residents are made aware of what is to come. If people know what is coming, they are usually pretty good at making other plans. Like with many other social issues, public officials need to walk a fine line between overhyping this, like using the term “Carmageddon,” while also making sure that people are aware of the severity of the problem.

5. This would be a good opportunity to think about new transportation options in the Los Angeles region. As the map accompany the AP story shows, there are only a few routes across the Santa Monica mountains. The answer is simply not to construct additional highway lanes and more drivers will then use the highway.

6. This reminds me of some examples of cities that have eliminated highways, like the Embarcadero Freeway in San Francisco, and traffic has adapted. Closing the highway for a short time is a nuisance but if the highway was closed longer, I bet people would adapt.

Nevada opens path to driverless cars

Posted on by

Even though driverless cars are not a common product yet, Nevada has opened a legal path for driverless cars on the road:

Assembly Bill 511, the first such legislation in the country, allows the state’s Department of Transportation to draw up rules that would authorize driverless cars. The regulations would include safety standards, insurance requirements and testing sites.

A driverless car is defined by the bill as using “artificial intelligence, sensors and global positioning system coordinates to drive itself without the active intervention of a human operator.” That includes technology such as lasers, cameras and radar…

Stanford University robotics professor Sebastian Thrun, a project leader on Google’s effort, said that nearly all driving accidents are due to human error rather than mistakes by machines.

“Do you realize that we could change the capacity of highways by a factor of two or three if we didn’t rely on human precision on staying in the lane but on robotic precision, and thereby drive a little bit closer together on a little bit narrower lanes and do away with all traffic jams on highways,” he said in a speech at the TED 2011 conference this spring.

So how long until this becomes a reality? It seems like we have been hearing about these possibilities for years. Here are a few things that could be holding up the process:

1. The legal side of things. Perhaps Nevada is really a pioneer here and will get the ball rolling.

2. The technology is not quite ready yet. It doesn’t sound like this is the issue.

3. We were waiting for a few companies to really push this. It is interesting that Google seems to be getting a lot of the attention. Obviously, their main business is not driverless cars but they had the resources and interest.

4. The cultural side: are people ready to see driverless cars on the road? Even if they are proven to be safer, will people accept them quickly or will it take some time?

A new bridge in Wheaton highlights problems with the railroad tracks, north-south routes

Posted on by

The Wesley Street bridge in Wheaton recently reopened after being completely rebuilt. Here is how it was changed:

The project involved several components including demolishing the existing bridge and reconstructing the approach roads, according to a press release..

A stoplight has been added where Manchester Road, Bridge Street and Wesley Street intersect, and a change in traffic pattern will allow drivers to turn left onto Bridge Street. This turn was previously prohibited due to the structural deficiencies with the old bridge, the release said.

The new structure also does not have weight restrictions, opening it up to emergency vehicles, school buses and trucks.

This is the only news story online I could find that actually had a picture of the bridge (though it is not a great angle to show off the new road bridge). Particularly compared to the old bridge, the new one has some nice styling and is a nice addition to the landscape.

But the reopening of the bridge also highlights two long-running issues in Wheaton:

1. This is the only bridge/underpass near the downtown and when the bridge is out, drivers would have had to go west to County Farm Road and or to the east side of Glen Ellyn to avoid an at-grade crossing. For decades, the City of Wheaton has looked at possible plans to avoid the railroad tracks downtown. Unfortunately, any major construction would have altered the existing buildings near Main and Front Street, the heart of the historic downtown. (Wheaton has approved plans for a pedestrian underpass at Chase Street but this requires losing an at-grade crossing plus it is east of the downtown.)

2. One possible bridge/underpass solution touched on another issue: the lack of north-south routes through Wheaton. This is partly a legacy of the hub and spoke model of the Chicago area where railroad lines (and Wheaton was built on the first one) radiate out from the center of Chicago but the connections between these lines are rare. Several decades ago, the city considered linking up Naperville Road, which dead ends just south of the railroad tracks to Main Street so that there would be a single major road through downtown Wheaton. Again, this would have required a lot of work so plans never moved forward. Another option was to push Gary Road further south but this also would have required a lot of work. While this bridge is helpful in navigating around the railroad tracks, it still requires driving around the downtown and isn’t part of a north-south path through the city.

Class I railroads converge in Chicago region

Posted on by

Chicago continues to be a critical transportation hub in the United States. A recent short interview in Chicago said 70% of American rail traffic moves through the Chicago area and 6 of the Class I railroads in the United States run through the region. Here is a description of Class I railroads from the Department of the Interior:

There were 554 common carrier freight railroads operating in the United States in 2002, classified into five groups.

Class I railroads are those with operating revenue of at least $272 million in 2002. Class I carriers comprise only 1 percent of the number of U.S. freight railroads, but they account for 70 percent of the industry’s mileage operated, 89 percent of its employees, and 92 percent of its freight revenue. Class I carriers typically operate in many different states and concentrate largely (though not exclusively) on long-haul, high-density intercity traffic lanes. There are seven Class I railroads ranging in size from just over 3,000 to more than 33,000 miles operated and from 2,600 to more than 46,000 employees.

Here are the seven Class I carriers: “The Burlington Northern and Santa Fe (BNSD); CSX Transportation (CSX); Grand Trunk Corporation, which consists of the U.S. operations of Canadian National (CN), including the former Grand Trunk Western (GTW), Illinois Central (IC), and Wisconsin Central; Kansas City Southern (KCS); Norfolk Southern (NS); The former Soo Line (800) owned by Canadian Pacific (CP); Union Pacific (UP).”

Of course, this can lead to a number of issues:

1. The Chicago region has a large number of at-grade crossings and long freight trains are a nuisance for many drivers, particularly in denser areas.

2. This requires a lot of space to transfer cargo. In recent years, the newer intermodal facilities have moved further out from the city of Chicago with new facilities in Rochelle (west of DeKalk, south of Rockford) and the Joliet Arsenal.

3. Freight tracks closer to the city can be congested, delaying passenger trains.

The trick for the railroads (and others?) is to remind residents of the Chicago how important railroads are for transporting goods. In recent years, there has some more advertising about this, particularly touting the greener use of fuel compared to trucking. But more could be done within the region to provide evidence that Chicago continues to be important partly because of this traffic.

The history of the American Interstate before President Eisenhower

Posted on by

An excerpt from a new book, The Big Roads by Earl Swift, suggests the link between President Dwight Eisenhower and the American Interstate System is limited as the plans had been laid during the FDR administration and Eisenhower simply helped put together the Federal financing.

There is little doubt that the Interstate Act of 1956 was important as the Federal government promised a large percentage of the funding for new roads that would connect metropolitan areas. But students of American highways already know that highway planning and construction had already taken place before Eisenhower signed this bill:

-The Long Island Motor Parkway was a private highway opened in 1908 and later transferred to the State of New York.

-Robert Moses is renowned for his efforts to introduce highways to the New York City area.

-The Pennsylvania Turnpike was built across the state (with the first part opening in 1940) and other states, such as Ohio and Indiana, built roads to connect to this.

-In the Chicago area, highway planning had begun in the 1930s and several of the major highways, including the Congress Expressway (now I-290), the East-West Tollway (now I-88),  and the Tri-State Tollway (now I-294), were primarily built by the state and completed before 1960.

-There was a motorways commission formed in 1930 that that produced a framework for American highways.

Regarding highways, there was a lot that took place before Eisenhower became President and I may have to check out this book to see how it tells this story.

A “children at play” sign as a symptom of a larger issue rather than the solution

Posted on by

In Traffic, Tom Vanderbilt argues that Americans rely on a lot of road signs even though there is little to no evidence that having more signs increases the safety of drivers and pedestrians. As an example, Vanderbilt looks at the “children at play” signs:

Despite the continued preponderance of “Children at Play” on streets across the land, it is no secret in the world of traffic engineering that “Children at Play” signs—termed, with subtle condescension, “advisory signs”—have been proven neither to change driver behavior nor to do anything to improve the safety of children in a traffic setting. The National Cooperative Highway Research Program, in its “Synthesis of Highway Practice No. 139,” sternly advises that “non-uniform signs such as “CAUTION—CHILDREN AT PLAY,” “SLOW—CHILDREN,” or similar legends should not be permitted on any roadway at any time.” Moreover, it warns that “the removal of any nonstandard signs should carry a high priority.”…

If the sign is so disliked by the profession charged with maintaining order and safety on our streets, why do we seem to see so many of them? In a word: Parents. Talk to a town engineer, and you’ll often get the sense it’s easier to put up a sign than to explain to local residents why the sign shouldn’t be put up. (This official notes that “Children at Play” signs are the second-most-common question he’s asked about at town meetings.) Residents have also been known to put up their own signs, perhaps using the DIY instructions provided by eHow (which notes, in a baseless assertion typical of the whole discussion, that “Notifying these drivers there are children at play may reduce your child’s risk”). States and municipalities are also free to sanction their own signs (hence the rise of “autistic child” traffic signs)…

One of the things that is known, thanks to peer-reviewed science, is that increased traffic speeds (and volumes) increase the risk of children’s injuries. But “Children at Play” signs are a symptom, rather than a cure—a sign of something larger that is out of whack, whether the lack of a pervasive safety culture in driving, a system that puts vehicular mobility ahead of neighborhood livability, or non-contextual street design. After all, it’s roads, not signs, that tell people how to drive. People clamoring for “Children at Play” signs are often living on residential streets that are inordinately wide, lacking any kind of calming obstacles (from trees to “bulb-outs”), perhaps having unnecessary center-line markings—three factors that will boost vehicle speed more than any sign will lower them.

So the signs are more of a band-aid to a larger problem which Vanderbilt discusses more in his book: streets and roads are generally designed in America for cars to go fast rather than as structures that also accommodate pedestrians and other neighborhood activities. Signs can’t do a whole lot to reduce the effects of this structure even though citizens, local officials, and some traffic engineers continue to aid their proliferation. In a car-obsessed culture, perhaps we shouldn’t be too surprised by all of this: people want to be able to move quickly from place to place.

This all reminds me of the efforts of groups like the New Urbanists who suggest the solution is to redesign the streetscape so that the automobile is given a less prominent place. By putting houses and sidewalks closer to the street, planting trees near the roadway, allowing parking on the sides of streets, and narrowing the width of streets can reduce the speed of drivers and reduce accidents. Of course, one could go even further and remove all traffic signs altogether (see here and text plus pictures and video here).

I wonder if we could use Vanderbilt’s examples as evidence of a larger public discussion about the role of science versus other kinds of evidence. There may be a lot of research that suggests signs don’t help much but how does that science reach the typical suburban resident who is concerned about their kids playing near the street? If confronted with the sort of evidence that Vanderbilt provides, how would the typical suburban resident or official respond?

170 options for improving the Eisenhower

Posted on by

The Eisenhower expressway is a key artery for traffic entering and leaving Chicago. The public is now invited to look at plans, including 170 possible improvements, that have been developed and could be put into practice in the future:

In response, highway design engineers have come up with 170 different ideas to reduce gridlock and accidents on the Eisenhower. The plan also focuses on improving travel options for mass-transit riders and bicyclists and pedestrians using nearby arterial streets…

The possible solutions include widening the Eisenhower to four lanes in each direction for the entire length of the highway to make room for “managed lanes’’ that would handle car-poolers, express buses or drivers willing to pay tolls to commute more quickly during rush hours, according to IDOT planners.

An expansion of CTA Blue Line rail service, from its current terminus in Forest Park to DuPage County, and other new transit services are also on the table, officials said. They include a possible light-rail line and designating a bus-rapid transit corridor that would be open to express buses traveling between the suburbs and downtown at least part of the day…

Major improvements are needed because traffic volumes on the Eisenhower are up to 180,000 vehicles a day, making it one of the busiest and most congested expressways in the Chicago region, officials said.

It sounds like there are a lot of options on the table. As the article notes, this is now an issue because this road is handling much more traffic than was originally intended and the traffic is not just one-way (in to the city in the morning, out in the afternoon) but now goes both directions. I can also imagine that all of this will stir up some discussion: special toll lanes? Construction that will go on for years? More money spent on mass transit? It seems like multiple solutions are needed included getting more drivers off the road as well as improving the traffic flow along this stretch.

Of course, a lot of this is for down the road as the planning has to take place and the money has to be found:

So far funding is available only to continue preliminary engineering, which is expected to be wrapped up in the spring of 2013, officials said. Design would then take several more years.

“Part of our analysis is to examine the financing options,’’ Harmet said. “We are a ways away from construction.’’

While the discussion could just center on the Eisenhower, this could also lead to larger conversations about the role of highways and mass transit within metropolitan regions. If the Eisenhower, and other local highways, are continually issues, perhaps new things have to be tried and transportation has to be dealt with on a more comprehensive level within regions (see a study like this for a broader metropolitan approach).

The state of public transit in the 100 largest American cities

Posted on by

The Brookings Institution just released a new report, Missed Opportunity: Transit and Jobs in Metropolitan America, examining the mass transit systems in the 100 largest American cities. Here are some of the findings:

Nearly 70 percent of large metropolitan residents live in neighborhoods with access to transit service of some kind…

The typical metropolitan resident can reach about 30 percent of jobs in their metropolitan area via transit in 90 minutes…

About one-quarter of jobs in low- and middle-skill industries are accessible via transit within 90 minutes for the typical metropolitan commuter, compared to one-third of jobs in high-skill industries…

Fifteen of the 20 metro areas that rank highest on a combined score of transit coverage and job access are in the West…

With the primary focus of the report on jobs, there is a lot of interesting data. Here are a few things I noticed in going through the full report:

-Page 3 highlights three trends for metropolitan areas: “metro growth and expansion” with both city and suburban growth during the 2000s, “employment decentralization” (with a figure that only roughly 20% of metropolitan jobs are within 3 miles of the city center), and the “suburbanization of poverty.”

-Page 4 notes some of the problems of mass transit in today’s metropolitan regions: “old hub and spokes” which don’t work as well since “39 percent of work trips are entirely suburban” (a problem in the Chicago region, hence the need for the Star Line), “serving low-density areas” (a problem in many suburban areas and a recurring problem in the western suburbs of Chicago such as Naperville), and “spatial mismatch and the costs of transportation” (the idea that the people who work in certain jobs/industries don’t necessarily live near these jobs).

-Page 13 has an explanation for why they chose a 90-minute one-way commuting threshold in the study. If you change the threshold, the percent of jobs available changes quite a bit: “[A]cross all metro areas, the typical worker can reach about 30 percent of total metropolitan jobs in 90 minutes. At a 60-minute commute threshold, only 13 percent of jobs are accessible for the typical worker. For a 45-minute commute, the share drops to 7 percent.” This seems to be quite a high threshold but as they note, more than half of metropolitan commutes are longer than 45 minutes (according to 2008 American Community Survey data).

-Page 18 has a graph comparing the availability of high/medium/low skill jobs within 90 minutes by city or suburban setting. Interestingly, a higher percentage of jobs accessible from the city were high-skill while a higher percentage of accessible suburban jobs were low-skill.

-Pages 20-21 look at some of the differences between the West, with the most accessible mass transit and higher percentage of accessible jobs, and the South, the region at the other end of the spectrum. The findings about the South are not too surprising as it is known for sprawl but the finding that the West dominates the list of cities (15 of the top 20) is interesting. Does this suggest that these Western cities have made much more concerted efforts to provide mass transit?

If you look at the more specific data for the Chicago region, it appears to be fairly average compared to the other 100 metro areas.

General Motor’s “Parade of Progress” bus tour

Posted on by

General Motors has had difficulty in recent years but at one point, GM was important and big enough to cast a vision for America’s future. In addition to the “Futurama” exhibit which featured an impressive highway system, GM also had a bus tour that gave Americans a glimpse of the future:

General Motors’ research Vice President Charles Kettering (Boss Ket) decided to take GM’s show on the road. Between 1936 and 1956, the company’s “Parade of Progress” toured the U.S., Canada, Mexico and Cuba, visiting hundreds of towns and showing millions how working examples of modern technology would transform their everyday lives.

Eight 30-foot, streamlined buses led the parade, six with walk-through exhibits, one with a stage and one carrying equipment, while nine tractor-trailers carried the remaining gear, and new models of GM cars followed. The red-and-white buses would pull into a small town, circle the wagons at the football field, and the buses would open like clams while electric floodlights rose on poles. A crew accompanied the parade and erected a tent that could accommodate up to 1,500 people for a free technology show.

The show was such a success that GM built 12 Futurliner buses in 1940, after the New York World’s Fair. The parade continued to tour until Pearl Harbor, after which it was disbanded and the buses stored in Ohio. They wouldn’t see the light of day for 12 years, until the “Parade of Progress” was revived in 1953, with 12 buses. But the world had changed. TV had stolen the parade’s thunder, and even though the show included new exhibits — Highways of Tomorrow, How a Jet Engine Works, Wonders of Stereo, Kitchen of Tomorrow and What is the Atom? — it was over by 1956.

It really does seem like a bygone era: a bus tour of America that would pull into a community and residents would come out to see the technology of the future. It is interesting that the article notes that the television was part of the demise of these bus tours. With the information the television provided plus the information available to anyone today through the Internet, who needs to check out a bus tour? At the same time, these experiences are quite different in that they are solitary and more passive. Additionally, I imagine there could be quite a crowd or energy that would build at these exhibitions. This would be a Durkheimian “collective effervescence” experience. What would be the equivalent today: people showing up at the Apple store to see the latest technological wizardry? But this sort of experience would be about a single or just a few digital devices and less about an exciting vision of the future. Is there any place these days that offers a comprehensive and positive view of the future?

I also wonder how much these GM exhibits helped push the narrative of scientific and technological progress that seemed to develop in the post-World War II United States.
