PROMISE, a project in the DRIVE/ATT framework, is currently implementing pilot tests of traveller information services in two European cities. The two-way PROMISE traveller information services as they are implemented in the Gothenburg pilot installation are described. Based on the Groupe Spatiale Mobile cellular network and its Short Message Service (SMS), the users may request real-time traveller information from several existing information sources, e.g., for public transport, parking availability, road traffic information and road weather forecasts.
