The gradual introduction of automated vehicles (AVs) rises a variety of challenges. Besides technical issues, legal aspects need to be considered, as nowadays driving regulations are orientated towards human drivers. Policy makers will have to define a legal framework for AVs, which will also effect an AVs’ driving behaviour and therefore also impacts traffic flow characteristics. To investigate possible legal adjustments for AVs and their consequences, traffic flow simulation (TFS) is an established tool. However, applying TFS requires much simulation and modelling expertise. Hence, we present a newly developed simulation platform, which allows to intuitively define, simulate and analyse a simulation scenario for different generic multi-lane highway segments without extensive TFS expertise. In addition, five exemplary simulation scenarios are investigated, focusing on the effect of temporarily increasing the desired time headway of AVs on the main road in order to assist merging vehicles at the on-ramp. The results showed rather negative effects, as congestion was increased in space and time due to temporarily increasing the time headway of AVs.

摘要

The gradual introduction of automated vehicles (AVs) rises a variety of challenges. Besides technical issues, legal aspects need to be considered, as nowadays driving regulations are orientated towards human drivers. Policy makers will have to define a legal framework for AVs, which will also effect an AVs’ driving behaviour and therefore also impacts traffic flow characteristics. To investigate possible legal adjustments for AVs and their consequences, traffic flow simulation (TFS) is an established tool. However, applying TFS requires much simulation and modelling expertise. Hence, we present a newly developed simulation platform, which allows to intuitively define, simulate and analyse a simulation scenario for different generic multi-lane highway segments without extensive TFS expertise. In addition, five exemplary simulation scenarios are investigated, focusing on the effect of temporarily increasing the desired time headway of AVs on the main road in order to assist merging vehicles at the on-ramp. The results showed rather negative effects, as congestion was increased in space and time due to temporarily increasing the time headway of AVs.
