This chapter cites Swedish road accident statistics to indicate the main problem areas for cyclists, considers some possible solutions based on Road Transport Informatics (RTI), and estimates the effect of some of these measures on cyclists' safety. The most serious accidents are caused by: (1) cyclists passing right through a non-signalised urban intersection; and (2) cyclists passing through urban intersections while accessing a cycle track. Several RTI measures have been proposed in the DRIVE and PROMETHEUS projects, that could improve cyclists' safety. They include: (1) intelligent traffic signals able to detect bicycles; (2) speed reduction at intersections and at places where many cyclists are present; (3) warning drivers of the actual or possible presence of cyclists; (4) tutoring drivers while they are driving; and (5) giving different (not safety relevant) information to drivers in urban traffic. Because about 20% to 30% of road traffic accident casualties are cyclists, at least in Sweden, the authors conclude that the application of RTI technology must not neglect cyclists, even though it is mainly targeted at car drivers. The main scope for applying it to cyclists is in urban areas, where most cycle accidents occur. Despite some difficulties, RTI technology can improve cyclists' safety. RTI functions, implemented for cars, should not be allowed to endanger cyclists.
