Abstract
Cooperative Intelligent Transport Systems (C-ITS) are special type of Vehicular Ad-hoc NETworks (VANETs) that aim to create networks between vehicles to increase traffic safety, mitigate traffic congestion, and enhance driving comfort. Green Light Optimal Speed Advisory (GLOSA) is one the many use-cases of C-ITS. GLOSA aims to minimize trip time and fuel consumption by providing vehicles, via a wireless channel, with specific information to calculate an advisory speed to be respected when approaching a traffic light. However, Wireless communications are prone to packet loss and delay which could considerably impact applications and user experience. In this paper, we study the impact of network performance on the efficiency of GLOSA. We compare two different strategies to find advisory speeds, one that aims at reducing trip time and the other at reducing fuel consumption and CO 2 emission. Results show different impact of network performance on GLOSA depending on the strategy that is followed.
