Assessment of certain applications of Vehicle-to-Vehicle communication in an urban network

Hobeika, A.G. / Kim, T.

The success rate of wireless communication and spatial-temporal dispersion for "Vehicle-to-Vehicle (V2V)" are investigated based on the market penetration rate of equipped vehicles and wireless communication coverage in the realistic and large network. Both average success rate and area coverage level increase as the market penetration rate and wireless communication coverage increase. At least 90% of equipped vehicles success to communicate with nearby equipped vehicles in Whole Network case. All Selected Links cases have lower average success rates of communication than Whole Network cases because equipped vehicles on the selected links cannot communicate with other equipped vehicles travelling on unselected links. The average area coverage level is used to assess the spatialtemporal dispersion of equipped vehicles. The market penetration rate of equipped vehicles has a greater influence on spatial-temporal dispersion of equipped vehicles. The Selected Links case has higher average area coverage level than the Whole Network case although it has lower success rate of communication. This is because 77.5% of total vehicles are on these selected links and the total lengths of selected links also are much smaller than the total lengths of all links in the study area. The average area coverage varies by time of day and is sensitive to the density of traffic. Finally, the spatial-temporal dispersion of equipped vehicles increase as the density of traffic increases, i.e. more equipped vehicles are able to communicate with one another.
