Informing people of disturbances in the transport infrastructure involves co-ordination between many people sending and receiving information. In the process of delivering messages, care must be taken not to mislead or confuse their recipients. The information provided must be complete and correct. This article describes the OJJE system, which includes all the necessary functions and tools to provide users in Sweden with optimal support in this process. The Swedish Broadcasting Service (SR) considers a traffic service to be an important part of its public service. Sweden may soon have a situation where a large part of this service is available to all listeners, including those who are not mobile. SR aims to integrate the traffic service with its other programmes. Daltek has developed guidelines to develop OJJE as an efficient common tool, with an information database, based on a digital map and the ability to determine and verbalise positions rapidly and accurately. The information must be available from many information providers in real time, and continually updated. OJJE uses a broadcast plan calendar to schedule a manuscript for broadcast. As an illustrative example, the article shows how OJJE handles information about an accident occurring on a public road.
