The widespread adoption of carpools which can have a benefit/cost ratio of 47 to one, and the advantage of speedy implementation with little or no capital outlay, could help ease the current environment and energy-related problems. Rush hour congestion will be reduced, overall travel speed will be increased, and emissions and fuel consumption will be reduced. Urbanwide carpool programs implementable by 1975 can produce reductions in emissions far exceeding the absolute reduction in vehicle miles of travel. The smog generation problem between 6 a.m. and 9 a.m. is discussed in relation to speed and vehicle emissions. Whereas park-ride and kiss-ride facilities will not solve the problem of high emissions generated during the cold-start/hot-soak cycle of pollution controlled automobiles, vehicle pooling will offer a solution. Adding 2 or 3 more people with similar time-origin-destination to a vehicle, dramatically reduces the energy consumed per mile. An increase of rush hour auto occupancy by 30 percent can save 5 percent of the total highway fuel and 3 percent of the nations transportation fuel needs. Studies have shown that acceptable service is the most important factor in ride sharing. To optimize carpool formation, a comprehensive program consisting of 3 phases: carpool patching, public information, and incentives are recommended. The most successful incentive is identified as parking privileges for carpools. Other incentives (priority freeway lanes, higher tolls for single occupancy) are briefly reviewed. Comments are made on the increase in taxi use.
