The goal of smart-highway technology is to make traffic systems work at optimum efficiency by treating the road and the vehicles traveling on them as an integral transportation system. Proponents of this advanced technology say electronic detection systems, closed-circuit television radio communication, ramp metering (斜坡坡度計量), variable message signing, and other smart highway technology can now be used at a reasonable cost to improve communication between drivers and the people who monitor traffic.

　　Pathfinder, a Santa Monica, California based smart highway project in which a 14 mile stretch of the Santa Monica Freeway, making up what is called a "smart corridor", is being instrumented with buried loops in the pavement. Closed circuit television cameras survey the flow of traffic, while communications linked to properly equipped automobiles advise motorists of the least congested routes or detours (便道).

　　Not all traffic experts, however, look to smart-highway technology as the ultimate solution to traffic jam. Some say the high-tech approach is limited and can only offer temporary solutions to a serious problem.

　　"Electronics on the highway addresses just one aspect of the problem: how to regulate traffic more efficiently, "explains Michael Renner, senior researcher at the Worldwatch Institute. "It doesn't deal with the central problems of too many cars for roads that can't be built fast enough. It sends people the wrong message. ""They start thinking, ‘Yes, there used to be a traffic congestion problem, but that's been solved now because we have an advanced high-tech system in place. '"Larson agrees and adds, "smart highway is just one of the tools that we will use to deal with our traffic problems. It's not the solution itself, just part of the package. There are different strategies. "

　　Other traffic problem-solving options being studied and experimented which include car pooling, rapid mass-transit systems, staggered or flexible work hours, and road pricing, a system whereby motorists pay a certain amount for the time they use a highway. It seems that we need a new, major thrust to deal with the traffic problems of the next 20 years. There has to be a big change.
