ENERGY EFFICIENCY OF TRAFFIC CONTROL MODES AT PEAK HOURS. THE CASE OF A MEDIUM-SIZED CITY. ENERGY EFFICIENCY IN LAND TRANSPORT. PROCEEDINGS OF A SEMINAR ORGANISED BY THE COMMISSION OF THE EUROPEAN COMMUNITIES, DIRECTORATE GENERAL FOR ENERGY, LUXEMBOURG, MAY 16-18, 1988

This article describes trials undertaken to compare 4 different methods of traffic control on the 3.5 km ring road in aix-en-provence during the evening rush hour. One medium sized and one small car were driven along the route several times and the following characteristics were measured: length and duration of journey; maximum speed; fuel consumption at rest, when idling and when running; and length of stationary periods. The 4 traffic signal control regimes tested were: (a) a reference mode, corresponding to optimized fixed signal plans using thebes; (b) a "green wave" corresponding to usual settings used by the city (average speeds being 44 km/hr); (c) an adaptive algorithm, based on a real time system; and (d) partial dissynchronization. Results showed that energy conservation was highest with the thebes optimized fixed time plans. Further analysis showed that those methods which produced the highest average and maximum speeds (thebes and green wave) also consume the least petrol.
