A PRACTICAL, PROGRESSIVE, AND EVOLUTIONARY SOLUTION TO TRANSPORT PROBLEMS: DUAL-MODE SYSTEM IN EVRY

The new town of Evry, located to the south of Paris, installed its public transportation system on an exclusive right-of-way bus lane in the main part of the city. This led to the choice of a dual-mode system intended to provide attractive service to be used by at least 45 percent of the people traveling within the town. The reserved lane is shaped like a huge figure eight across the town. It penetrates to the limit of housing, factory, and shopping areas, linking them with the existing small towns situated within the limits of the new town, the public administrative offices, and the center of the city under construction. At the time the master plans were prepared, the planners retained the flexibility of using a variety of different transport systems based on the dual-mode concept. A study was made of existing and planned equipment and systems from the simple bus operating on a reserved lane to the most sophisticated computer controlled automatic system. The objectives of the study were; To identify a rapid and comfortable transit system for all commuters in the town at a reasonable cost for the community and for the commuters and; to select an evolutionary transportation system that could be adapted to the development of the town and to foreseeable technical innovations. Logical and mathematical models were developed to compare the systems proposed, giving for each of them the capital and operating costs, the quality of the service offered, and the sensitivity of demand to the variation of the quality of service. The analysis revealed that greatest attention is given to the effect on cost, design, and appearance of the busway with respect to variations in use of automatic devices (including an automatic steering device), speed and type of vehicles, traffic signal system, and unauthorized vehicles in the busway. /Author/
