Traffic Tools

Commuters are likely in a tizzy down south, as the annual awards for most congested U.S. city have just been awarded. Headlines and TV news spots usually greet the yearly report of the Texas Transportation Institute, and although the results don't really surprise anyone, the message has brightened a little. Of course Los Angeles wins again as the City With Highways Everywhere But No Place to Drive, where the average rush hour trip now takes 75% more time than the same trip off-peak. Across the U.S., the average delay to drivers increased, with 5.7 billion gallons of gas wasted and 3.5 billion hours of lost productivity. Using the most-up-to-date figures possible, congestion-induced productivity losses hit US$69.5 billion in 2001, US$4.5 billion more than in the previous year. Unlike past rankings, the traffic researchers departed from the usual note of gloom, and shed light on some gridlock remedies that may be working -- the same tools that are barely used here in the GTA.

Also scrutinized was the old-school method of reducing traffic jams -- highway building. While new roads were found to slow an increase in congestion, almost no cities in the US were able to build enough to make a difference. Instead, it is a set of relatively low cost solutions that may be the motorist's saviour. The rapid clearing of collisions got high marks, which may encourage officials in Ontario who are currently studying procedures used in U.S. cities. Next are freeway entrance ramp meters -- simple traffic signals that regulate how smoothly cars flow onto a highway. They are used extensively on California's overburdened roads, and a few can be found on the QEW in Mississauga.

The next implement in the gridlock tool bag is also rare in the GTA: traffic signal coordination. The City of Toronto is slowly refitting its major thoroughfares with technology that senses traffic volumes, and can react to back-ups by changing the timing of green lights. Extending the system to every arterial will take decades at the current rate.

The American approach to slowing the rate of congestion growth appears to include a complex range of responses, and while Canadian cities can peer over the border for ideas, there is no home-grown research going on here. No one is comparing the traffic troubles of Vancouver, Montreal and Toronto, let alone the unique experience of other Canadian cities.

One clue is that the federal government in Washington DC works closely with the states, because it doles out the proceeds from fuel taxes and has a hand in deciding how they should be spent. The federal government that resides in Ottawa is only now considering spending some of the billions taken in from fuel excise charges, and we all know how hard it is for Ottawa to hand out money without attaching strings.

If it comes true, and Paul Martin does start dishing out gas tax funds when he assumes the job of prime minister, he should know which projects are worthy, and which are poorly-studied cash holes. And until federal money starts to flow, there is no point for any national research body to study Canada's traffic problems and propose solutions.

Even if some "Alberta Transportation Institute" were to ride over the hill to rescue motorists trapped on the 401, armed with the best gridlock-fighting weapons ever devised, it could still miss the big picture. The way our cities are laid out defines how bad traffic will be, not the number of highway lanes or fancy  traffic gizmos. These amount to ineffectual tweaks if we avoid asking the big question; "What kind of city do we want to live in?"
