DSRC-based rear-end collision warning system – An error-component safety distance model and field test

Abstract

Dedicated short-range communication (DSRC) technology can provide drivers with information about other vehicles that are beyond the normal range of vision and enables the development of driving support systems such as the rear-end collision warning system (ReCWS).However, technology constraints such as communication delays and GPS error affect the accuracy of a DSRC-based ReCWS. This paper proposes a ReCWS design that explicitly represents functional specifications of DSRC technology, including transmission delay specifications that describe the information transmission process and an error-component safety distance specification used to represent the effect of GPS error and the information propagation delay. We propose three collision warning strategies each with different deceleration requirements. The system is assembled with off-the-shelf DSRC and mobile technology that can be readily installed into test vehicles. To test the effectiveness of the proposed ReCWS, we ran a variety of controlled scenarios on a test track. The results show a high degree of warning accuracy. These field test results also provide calibrated system parameter values for future studies and designs of DSRC-based ReCWSs.

A Safety Collision Avoidance Algorithm Based on Comprehensive Characteristics

“…DSRC is an efficient wireless communication technology that can quickly identify high-speed moving targets and two-way communication within a short distance [21], enabling wireless communication between vehicles and vehicles and vehicles and roads in intelligent transportation systems [22]. DSRC can provide a high data transmission speed, ensuring the low latency and low interference in the transmission process [23]. Besides, DSRC can transmit a large amount of real-time information in the intelligent transportation system quickly [24].…”

A Survey on Secure Computation Based on Homomorphic Encryption in Vehicular Ad Hoc Networks

“…Most vehicular communications are based on dedicated short range communications (DSRC) [75][76][77]. These are particularly designed for achieving low latency and high reliability in vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications [78,79].…”

Analysis of V2V Messages for Car-Following Behavior with the Traffic Jerk Effect

“…is paper used the car-following data of CVs previously collected by our research team (see Figure 1) [33,34] to analyze the impact of V2V communication on the jerk e ect in tra c ow (i.e., to evaluate the correlation between the jerk e ect and car-following behavior in inactive and active V2V cases). e site selected for the experiment was the 2.4-km circular runway of the Chang'an University's vehicle testing eld.…”
