Abstract

The use of road transport informatics (RTI) is a recent development that optimises the use of existing facilities in the transportation system and serves three main goals: alleviation of congestion, diminution of air pollution, and reduction of incidents. RTI instruments deal with traffic information. Examples of RTI systems are pretrip planning, roadside displays, radio data system-traffic message channel, and in-car navigation. To model the effects of providing the road user with information a method is used in which stochastic and deterministic assignments were compared for both networks with and without congestion. To let information also effect destination choice and the spatial distribution of activities, the assignment models were combined with different distribution models. The amount of information that travellers have was translated to a "level of uncertainty"measure. The more informed a traveller is, the lower the level of uncertainty. Since the effects appeared to be network dependent, a number of different networks were examined. Simulations show that the amount of kilometres driven decreases when travellers are provided with better and more information. This paper appears in Transportation Research Record No. 1306, In-vehicle Information Systems: Modelling Traffic Networks and behavioural Considerations 1991.
