Temporary Hard Shoulder Use in Hesse – Effects on Traffic Flow and Road Safety

Temporary hard shoulder use is an effective measure to increase the capacity of frequently congested motorway sections. In the German State of Hesse, this measure is successfully applied on heavily trafficked sections of the motorways A 3 and A 5. The paper examines the effects of temporary hard shoulder use on traffic flow and road safety. It is shown that the capacity of a three-lane carriageway is increased by 20 - 25 % if the hard shoulder is used as an additional lane. The analysis of accident data yields that temporary hard shoulder use does not affect road safety.
