Sensitivity Analysis on Regularity Based Driver Advisory Systems

Abstract

Thanks to the introduction of Cooperative ITS, new methods can be proposed in order to reduce stop-and-go at traffic lights without solely relying on Transit Signal Priority. Driver Advisory Systems (DASs) are shifting the objective of reducing stops at traffic lights to the drivers by providing instruction of the optimal dwell time and speed profile. Recently, the objectives of DASs were extended in order to account for the regularity of the transit lines. In this work, we conduct a sensitivity analysis on the infrastructure and operation related factors that affect the performance of regularity based DASs. We test these parameters on a central avenue of the city of Luxembourg using simulation. The results show that regularity DASs are more efficient in great headway variations and both distance and cycle length affect their performance.
