Driving? Miss Denver

TREX and E-470 have it all backwards. A beltway is supposed to relieve the downtown of the traffic burden of mainline highways crossing the city. Travelers who want to go through Denver should be encouraged to drive the extra miles, on very nicely built roads with high speed limits, to skip the traffic and the hassle, and even to relocate some of the air pollution away from downtown. Ten bucks of tolls does not constitute encouragement to drive 46 miles instead of 32, especially for heavy trucks whose per-mile and per-minute costs are higher.

So the Fûz Proposal, which is cunning but simple, but cunning, and promotes the Interstate highways as they were intended---regional highways, not local commutes:
  • Raise the bucks to pay off E-470 by reserving a High-Occupancy/Toll lane in T-REX. Try express lanes like those for the I-270 spur from the District of Columbia to Frederick, Maryland, just to segregate the local traffic from the big trucks who are mostly passing through. It can be simplex (one way at a time) like the HOV lane up North through the Mousetrap---but Northbound in the morning, Southbound in the evening. It can be toll-free during those times when there's no traffic congestion.
  • Provide a limited number of places where a car can cross from express to local lanes. Charge a toll at these crossovers, whether the vehicle is highly occupied or not. Some drivers will choose to use the express lanes to penetrate the layers of traffic, then change to local lanes when their exit comes up, instead of suffering the start-stop in local lanes the whole way. For example, pay twenty-five cents to cross to local at Arapahoe to exit at Belleview Ave, instead of using local lanes the whole way from Lincoln Street to Belleview. Charge a toll for any vehicle crossing from express to local lanes, whether the vehicle is highly occupied or not.

Instead of E-470's RF toll transponders, how about prepaid cards that bear a large barcode? The traffic authority encrypts the bar code so cards are hard(er) to counterfeit, and sets the tolls low enough so they're not worth counterfeiting.
Privacy geeks can pay cash for the cards to disconnect the driver's identity from gate and time. Flash the card at a reader on the toll gate. The gate flashes back how much value is left on your card for the next gate.


These two incentives will combine to push some local traffic out to E-470, and make any North-South through traveler think twice about going direct through Downtown.

Some through-traffic motorists will spend the extra operating costs, and the extra time, to go around; others will choose to pay the toll to go straight through (the toll booths at the very Northern and Southern ends of the HOT lane will have to be manned, so out-of-towners can buy toll cards, high-occupancy cars are admitted, and local tollers can get their cards recharged). Either way, the long-distance through travelers get to choose.

I'd take a kinder view of professional sports if the Denver Broncos comped the tolls for I-25 through traffic during certain home games. Their advertising budget could handle it.

The backs of the prepaid toll cards are a great advertising space for tow services, DWI public service announcements, jitney services, and so forth.


Local traffic can:
  • slug it out on the local lanes of I-25, paying nothing but aggravation and engine hours to weave among each other in slow motion through the Tech Center, or
  • they can pay extra to take the HOT lane in to a crossover near their exit, or
  • they can pay the extra time and operating costs to use the beltway.
They get 3 options because there are more of these motorists, they tend to be on the roads at about the same times, and their origins and destinations are more numerous. Either way, they get to choose and they can see the consequences of their choices more clearly. No market distortions are hiding the consequences from them.

We can reduce traffic congestion, fuel consumption, and pollution only if the individuals who are creating it have a choice in how to reduce it, and still have lives. Their choices can be informed only by the measurable costs of money and time. Their money and their time, by the way.

Unfortunately, the choices already have been made by our betters, and the highways being built are literally casting those choices in concrete.
