Traffic statistics paint a gloomy picture. To help solve their traffic woes, some rapidly growing U.S. cities have simply built more roads. But traffic experts say building more roads is a quirk-fix solution that will not alleviate the traffic problem in the long run. Soaring land costs, increasing concern over social and environmental disruptions caused by road-building, and the likelihood that more roads can only lead to more cars and traffic are powerful factors bearing do you a 1950s-style construction program.
The goal of smart-highway technology is to make traffic systems work at optimum efficiency by, treating the road and the vehicles travelling on them as an integral transportation system. Proponents of this advanced technology say electronic detection systems, closed-circuit television, radio communication, ramp metering, 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.
Not all traffic experts, l however, look to smart-highway technology as the ultimate solution to traffic gridlock. 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 problem 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 highways 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 s, strategies.”
Other traffic problem-solving options being studied and experimented with 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.

Passage Three
Ⅰ. At a pedestrian crossing:
a) When you have stepped off the pavement on to a zebra crossing, traffic must stop to let you cross. But don’t be foolish: make sure that drivers have enough time to give way to you.
b) If a police officer is directing the traffic, watch for his signals. Do not cross until he holds up the traffic.
c) At a crossing with traffic lights, do not cross in front of traffic which has the signal to go.Ⅱ. At a bus or tram stop:
If you want to get on a bus or a tram’ give a clear signal for it to stop and do not step into the road until it has done so. When you get off a bus or a tram and wish to cross to the opposite side of the road, do not walk behind the vehicle. Wait until the vehicle has moved off and make sure there is no other traffic before you cross the road,

A:make sure that drives have enough time to give way to you B:cross the road in the same direction as the traffic C:wait until there is a traffic hold-up D:wait until the light for the traffic changes to red
