Advanced Driver Assistance Systems: Traffic Impacts Assessed by Micro-simulation

This report presents results of research carried out in the ADVISORS project. The objective of this research is to develop a methodology to assess road traffic efficiency and environmental impacts of Advanced Driver Assistanc e Systems (ADAS) at both the microscopie and the network level. The results discussed in this report pertain to the microscopie analysis, in showing the impact ofADAS on bottleneck capacity and capacity distribution among the main-road and the on-ramps (if applicable) for both Autonomous Intelligent Cruise Control (AICC) as weil as Intelligent Speed Adaptation (ISA). Moreover, impact on traffic safety and driving comfort are studied indirectly, by considering cumulative exposure times to Time-To-Collision values that can be considered to be either unsafe and uncomfortable. This impact analysis is carried out using the microscopie simulation model SIMONE, developed by Delft University of Technology
