Abstract:
In some 50 miles of Los Angeles freeway, the California Division of Highways is taking a systematic approach to eliminating traffic congestion. The actions include: changeable message signs to help motorists avoid delay locations, on-ramp traffic signals to keep the freeway from getting so full that traffic slows, early detection and rapid removal of unusual incidents, and service for stranded motorists. Electronic detection plus roving tow trucks reduced the average accident-removal time from 42 to 21 minutes. Among benefits: reduction of vehicle delays by 260,000 vehicle-hours per year, yielding a $1,000,000 saving.
