Evaluation of Incident Information Transmission over Inter-Vehicle Communications on Highways

This paper presents the evaluation of the incident information transmission on multiple lane highways from a vehicle that detects or encounters an incident to following vehicles over the inter-vehicle communications by relaying the information. The transmission is evaluated with the incident information transmission range with the parameters of the communication unit penetration rate and the traffic volume. The evaluation is conducted with simulation studies based on the Monte Carlo method. The studies include to investigate the influences of the traffic flow models and the number of lanes on the relationship between the penetration rate and the transmission range, and the results show that the number of lanes and the traffic flow models do not influence the relationship. The simulation results for a single lane highway indicate that the system will be feasible when the rate is 10 to 20 % depending on the traffic volume: for example, the penetration rate of 18 % for 10 vehicles per communication range. The penetration rate for a 2 or 3 lane highway would be a half or one third of the penetration rate for the single lane highway, which means the system would work at the rate of 3 % or 7 %.
