Abstract
A study was carried out in connection with the demon-stration project on redesigning urban areas in Eindhoven. Comparisons were made between conflict-free and parallel traffic control systems. Conflictfree phases for cyclists and moped riders going straight on at the intersection can have positive effects on road safety, provided we can keep red light violations under control. Conflict-free phases are to be considered especially where there are many cyclists and moped riders conflicting with trucks turning right.
