Chicago may get congestion pricing, so says Illinois media. However, it isn't quite what most of us in the wider tolling/highways sector know as congestion pricing. The proposals released by the Chicago Metropolitan Agency for Planning (CMAP) are NOT to charge vehicles for using an existing untolled road or lane. There will be no cordon, area, zonal or distance based charge on existing roads. So there wont be the kind of behaviour change or modal shift seen in Singapore, London or Stockholm.
What is proposed are two new roads to be tolled, with pricing that will vary by time of day and new HOT lanes to be constructed on existing corridors. The proposal is for new capacity which will be tolled.
The new capacity will obviously mean significant travel time savings (and commensurate fuel/vehicle operating cost savings) for those using that capacity. The shift of those users from existing capacity will deliver incremental savings to those remaining on the existing network.
However, what CMAP is proposing is tolling the new capacity, which creates two benefits. The obvious one is recovery of at least part of the capital cost of the new capacity. However, the more significant benefit is ensuring the new capacity is sustainable. I don't mean to use the word as a cliche, but rather than by having peak pricing, the new roads and the HOT lanes in particular, will be able to be managed to always have a minimum standard of free flow conditions with pricing managing demand.
Critics of any new highway capacity frequently claim that it induces demand so that it ends up being filled up and congested, much as the situation before it was built. Pricing that capacity manages this so that demand can be effectively capped by pricing off users for whom the marginal cost of the toll outweighs the marginal benefit of travelling on that road at that time.
In short, it is a way of ensuring new capacity, where and when it can be funded by the users, is optimally utilised.
It is great step forward in debating transport policy in Chicago.

CMAP's plans for more tolled capacity in Chicago
CMAP has published a website outlining its plans, which are interesting and resemble the scale of development currently underway in Los Angeles. The technical report behind the analysis is here.
It's worth noting that it appears CMAP has published findings and proposals largely to gauge reaction to them. The peak surcharge on tolled routes (i.e. not including the HOT lane only routes, where the alternative is free) would range from 25-83%, with a price surcharge of between US$0.05-US$0.09 per mile.
A map of the proposed network consists of:
Illinois Route 53 north extension and Illinois Route 120 bypass: A 12.5 mile long four lane parkway, with an operating speed limit of 45mph and all lanes priced, with peak pricing to maintain steady traffic flows.
Elgin-O'Hare West Bypass: Widening (from four to eight lanes) and extending the existing Elgin-O'Hare Expressway to a new north-south expressway at the western edge of O'Hare to connect I-90 and I-294. Modelling was on the basis of tollling all lanes including peak pricing.
I-90 Addams Tollway widening: A new lane to be added in each direction on the Addams Tollway from I-294 to Rockford, with those lanes being HOT lanes with peak pricing.
I-290 Eisenhower Expressway widening: Additional new HOT lane with peak pricing.
I-55 Stevenson Expressway widening: Additional new HOT lane with peak pricing.
Travel time savings were expected to range from 11-25 minutes in the tolled lanes, and 4-9 minutes in the untolled lanes (with other time savings for the new corridors more related to a better route than pricing)
CMAP advocates the new "congestion pricing" (which is effectively tolls on new capacity with peak pricing, not congestion pricing as it is known elsewhere) as offering the typical benefits of tolled lanes, of new capacity and a choice of road users to pay for free flow conditions or to remain in congested traffic (which will be less congested given the impact of those making the choice to pay). It indicates that time savings in express lanes could be between 31% and 66% of existing travel times. In addition, it sees the express lanes as enhancing the attractiveness of bus services, as they effectively create new corridors for bus rapid transit services.
Issues identified
It lists and addresses challenges such as equity, saying:
"The median income of express lane users would be 13 to 19 percent higher than users of the general purpose lanes -- somewhat higher, but not dramatically so" Astonishing that this issue comes up, given Americans are comfortable with wealthier people being more able to afford taxis, cars and first class air travel. Bear in mind the lanes are optional.

Bear in mind the lanes are optional.
However, it floats some more ideas to address perceived distributional issues:
Policies should be adopted to address equity concerns. For example, transit vehicles could use express lanes for free, and surplus revenues from congestion pricing could be used to fund transit service. In another approach, drivers in the region could be given a base number of "lifeline" travel credits for free travel, then they would only pay for travel above that level. Another possible alternative is that lower-income drivers could be charged a discounted toll rate or be allowed to deduct tolls from congestion pricing on their state income taxes.
Free use by buses is fairly obvious, but having travel credits for free travel will destroy their usefulness in the initial period, as everyone uses their "free" credits early on. Having a low income discount is also fraught with problems, although deducting tolls from income taxes would be an interesting form of tax recycling. Yet none of this is necessarily. New toll routes or toll lanes don't disadvantage anyone, but offer a new opportunity.
Other concerns such as "traffic spillover" and "engineering feasibility" are manageable. If all such lanes are new capacity, the traffic effect would be generally positive, but engineering matters can be complex to allow for convenient access/egress from such lanes.
The "public acceptance" page indicates a majority of those surveyed are in favour of the option of tolled lanes that guarantee free flowing traffic conditions. Hopefully this will prove to be the case to encourage the proposal to proceed further.
Media Reports
Media coverage has been fairly open minded:
- Huffington Post Chicago has a short factual report and has video from ABC7 and strangely the BBC (talking about tolling in the UK), but also has an online survey of attitudes to toll lanes.
- Chicagoist is open minded about it, and claims "This is not a new idea. Mayor Rahm Emanuel previously proposed a downtown parking surcharge to help fund transit initiatives like a new Cermak / McCormick Place El stop and bus rapid transit routes along Jeffery, Western and Ashland avenues." Although parking surcharges bear little resemblance to toll lanes.
- Chicago Magazine titled its report "Why Congestion Pricing Works, and Why People Don’t Like It", gets the basic economics right and quotes the success of Singapore, but notes people don't always like others paying to get past a traffic jam. It has an interesting conclusion that helps people understand the tradeoffs being made, and notes that whatever people say, users of the untolled lanes get a benefit:
Let's assume you save 15 minutes on Mannheim. That's one-quarter hour, at $3.41. If you make $20 an hour, and value your commute at $10 an hour, it's not worth paying $3.41. It's close to worth it on I-55. But if you make $40 an hour, it's (theoretically) worth it. (I look forward to traffic reporters trying to integrate variable congestion pricing into their reports: "40 minutes to the Dan Ryan from 355 in the free lanes, 25 in the express lanes, which are running at eleven cents a mile right now.")
Is it unfair ? Sort of—the more you make, the more affordable it is, which is frustrating if you don't make much. But it also shaves time off the free lanes, which building more roads has never done.
- Radio Station WBEZ unsurprisingly mentioned London, even though there is little in common between London Congestion Charging and the Chicago proposal.
- ABC gave a fair report but indicated it "may be a tough sell to many who are weary of the higher cost of everything, including the most recent toll hikes" and that "Many public hearings ahead will determine the direction of travel". It noted that just building new untolled lanes is likely to not be sustainable.
It will be interesting to see if there is any significant opposition, and if not, if Chicago will start to advance these proposals. Bear in mind Chicago already has toll roads in the form of the Illinois Tollway, and the privately owned Chicago Skyway. If you combine the proposals for new roads and HOT lanes with these, you get the map I have hastily pulled together below. Red is for toll roads, both existing and proposed, yellow is for untolled roads with HOT lanes (one existing toll road, the I-90 Adams tollway is proposed to have a toll premium lane added, so that it costs yet more to use it compared to the existing toll road). (Note the state line immediately to the east for Indiana, as the Indiana Toll Road connects to the Chicago Skyway).

As a footnote, perhaps one of the more interesting pieces of work on the website is a summary of "congestion pricing" across the United States. These examples include toll roads with peak pricing and HOT lanes, all with links to the websites about the current and planned projects. It's not a bad summary of such pricing in the US (there is only one example I know of HOT lanes outside the US, being in Israel).
