Sensitivity Analysis on Regularity Based Driver Advisory Systems

Thanks to the introduction of Cooperative ITS, new methods are introduced in order to reduce stop-and-go at traffic lights without solely relying on Transit Signal Priority. Driver Advisory Systems (DASs) shift the objective of reducing stops at traffic lights to the drivers by providing instruction of the optimal dwell time at bus stops and the speed profile. Recently, the objectives of DASs have been 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. results show that R-GLOSA is more effective in restoring regularity but its performance is limited for high demand and long cycle length, conditions under which R-GLODTA performs adequately.
