TU Dresden, A Traffic Safety Plan for DresdenSlide 3 01 Introduction General Information: Capital of Saxony with about inhabitants. Road Traffic Safety: Overall about accidents (including material damage) in 2005, more than people were injured. Every year about 100 persons get injured in accidents at turned-off traffic lights. Every year about 90 collisions of left-turning drivers with oncoming traffic take place at traffic lights. Approximately 500 persons are injured in right-of-way-accidents involving bicyclists every year. City of Dresden

TU Dresden, A Traffic Safety Plan for DresdenSlide Major Issues Action plan for 60 black spots Approach: Based on the ranking of black spots, an action plan was worked out in order to eliminate 60 black spots in Dresden. The spots were ranked by means of benefit-cost-estimations. Results: The investment costs for the measures suggested amount to about €. The annual cost can be estimated at around € p. a.. The benefit adds up to € p. a.. This leads to a benefit-cost-ratio of approximately 15.

TU Dresden, A Traffic Safety Plan for DresdenSlide Conclusions Results: The City of Dresden is now fitted with a short-term concept in order to improve the road traffic safety at 60 spots effectively. The action plan is ranked by means of benefit-cost-ratio and allows a highly efficient use of resources. Results are provided to support a safe development of road infrastructure in the long-term. The analysis of safety potentials throughout the main road network builds a basis for an appropriate consideration of road traffic safety in the future planning process.
