TLDR
It was found that Iatency had a counterbalancing effect on vehicle spacing and relative longitudinal speed that led to insignificant changes in the final spacing that demonstrated the need of a variable time headway.Abstract:
Active safety is of utmost importance in heavy road vehicles due to the relatively higher number of fatalities encountered in their accidents. Vehicle-to-Vehicle (V2V) technology, which is seen as a future of connected vehicles, can potentially complement onboard sensing to reduce the time taken for detection, and to plan the path with the information available from road side units (RSU). This paper investigates the effect of Iatency in (V2V) communication on a collision avoidance algorithm developed for heavy road vehicles. Experiments performed on a Hardware-in-Loop (HiL) setup were used to evaluate the effect of Iatency for various scenarios. It was found that Iatency had a counterbalancing effect on vehicle spacing and relative longitudinal speed that led to insignificant changes in the final spacing. Further, a sensitivity analysis done at different host vehicle longitudinal speeds demonstrated the need of a variable time headway.read more

Performance Analysis for the Coexistence of Radar and Communication in VANETs
TL;DR: A new coexistence model of vehicular long range radar (LRR) operating at 77GHz and dedicated short range communication (DSRC) system, in which each vehicle detects forward and transmits the detection results backward is proposed, which can effectively improve the detection range of a single vehicle.

Communication Latency and Speed-Dependent Minimum Time Headway for Connected Heavy Road Vehicle Collision Avoidance
TL;DR: It was observed that the incorporation of communication latency and initial longitudinal speed explicitly in the time headway formulation maintained the desired final spacing between the vehicles, over a range of communication latencies and various host vehicle longitudinal speeds, which was not the case when the above factors were not considered.

Effect of Packet Loss on a Connected Heavy Vehicle Collision Avoidance Algorithm
TL;DR: The effect of packet loss on the performance of CAA was investigated using a Hardware-in-Loop experimental platform and it was observed that the desired final spacing was maintained but, early braking was observed when the host vehicle followed the lead vehicle at close distances.

Collision avoidance timing analysis of DSRC-based vehicles.
Antony Tang,Alice Yip +1 more
TL;DR: It is found that the warning strategies for collision avoidance are constrained by the timing of events such as DSRC communication latency, detection range, road condition, driver reaction and deceleration rate, and they dictate the design of software-based collision avoidance systems.
