Safety benefits[ edit ] The main motivation for vehicular communication systems is safety and eliminating the excessive cost of traffic collisions. Also about 50 million persons are injured in traffic accidents. If preventive measures are not taken road death is likely to become the third-leading cause of death in from ninth place in Department of Transportation states that 21, of the annual 43, road accident deaths in the US are caused by roadway departures and intersection-related incidents.
One potential area to improve driver safety and traffic mobility is around merge points of two roadways e.
Due to poor visibility because of weather or complex road infrastructure, on many such entrance ramps, it may become difficult for the driver on the merging ramp to clearly see the vehicles traveling on the main freeway, making it difficult to merge.
This research project proposes to acquire real-time relative trajectories of vehicles traveling towards the merging junction using DSRC based V2V communication. The DSRC equipped vehicles traveling on the freeway and on the merging ramp will periodically communicate important traffic parameters such as their location, direction of travel, and speed, to each other.
Using that information, the relative trajectories of all DSRC equipped vehicles will be acquired and recorded in real time in the tablet or laptop computer connected with the DSRC equipment of the vehicle on the merging road.
We plan to acquire and demonstrate the real-time trajectories for the single lane merging scenarios in the first year and for the multiple lane merging scenarios in the second year. The successful completion of this project could pave the way to provide visual merge assistance to the drivers on the merging ramp, or facilitate automatic merging of the vehicles when DSRC market penetration ramps up in future.On the basis of connectivity, the global V2V communication market is classified into DSRC, and cellular based technologies.

Connected Vehicle: Cell of DSRC-based applications 9. Why DSRC Matters Up to 80% of non-impaired. The USDOT supported DSRC-based V2V and V2I connected vehicle test facilities, beginning with simple proof of concept testing, then expanding in to the "Michigan Test Bed," with vehicles and a .
This document provides recommendations of safety message minimum performance requirements between a Vulnerable Road User (VRU) and a vehicle. It addresses the transmission of Personal Safety Messages (PSM) from road user devices carried by pedestrians, . As a DSRC bearer protocol, LTE Direct can be used perfectly in the GHz allocation," he told FierceWirelessTech.
V2V (vehicle-to-vehicle) communications are nothing new.
