Abstract:
Vehicle-to-infrastructure communications can tell intersection controllers where and how fast connected vehicles are. Recent research has focused on adaptive intersection control algorithms that use this information.
These studies assume flawless communication. This study examines how a temporal decrease in communication channel reliability affects intersection throughput. Vissim and OMNeT++ simulate road traffic and DSRC-VANET communications.
Simulations of scenarios with challenging, but realistic communication distortions show significantly longer vehicle delays than scenarios with perfect communication. These delays are mostly independent of whether communication distortions affect all intersection approaches.
Delays increase unevenly across signal groups. Some decrease, resulting in unfair green time allocation. Lost communications can be corrected using previous data and simple vehicle movement assumptions.
This correction reduces delays in all scenarios for isolated and connected intersections. When all intersection approaches have uniform communication distortions, it performs like perfect communications. The results show that adaptive intersection control algorithms should consider communication distortions.
