Objectives in traffic system management

This paper discusses the objective of reducing vehicle fuel consumption and pollutant emissions in urban traffic conditions in relation to other traffic system management objectives. The existence of conflicts among various objectives (safety, traffic performance, fuel consumption, pollutant emissions, property access, intrusion into residential areas) and the needs of various road user groups (pedestrians, buses, cars, major road traffic, side road traffic) is emphasised. The discussion is centred around the tactical issues related to these objectives with a view to finding practical compromises which can be implemented. An elemental model of fuel consumption (pollutant emission, cost, etc) is described in detail. The importance of the correct prediction of the number of vehicle stops is emphasised; possible sources of error are discussed. The expected impacts of various short term traffic management measures on traffic performance, fuel consumption, safety and other objectives are summarised. The discussions of detailed matters are presented with the aid of examples of traffic signal control (a). This paper is no 80014.
