Dynamic Safety DistanceIn the traditional optimal velocity model, safe distance is usually a constant, which, however, is not representative of actual traffic conditions.This paper attempts to study the impact of dynamic safety distance on vehicular stream through a car-following model. Firstly, a ...
Considering high speed following on expressway or highway, an improved car-following model is developed in this paper by introducing variable safety headway distance. Stability analysis of the new model is carried out using the control theory method. Finally, numerical simulations are implemented, and...
In conclusion, the dynamic performance of traffic flow can be improved by considering the desired safety distance and the heterogeneity of driver's sensitivity in the car-following model. 1. Introduction In recent years, many cities worldwide have experienced traffic congestion and the accompanying ...
[18] showed that the car-following model considering the desired following distance can effectively improve the stability of traffic flow. Zhang et al. [19] believed that the driver can predict the change of the spacing headway and adjust the OV, ultimately optimizing the car-following behavior....
Together, they advanced the brake activation time, reduced premature acceleration, and activated, even at low speeds, at a 2-m minimum following distance. As Conclusion To explore ways to ensure the traffic safety of AVs in car-following scenarios, especially to reduce the risk of the AV ...
Back up as close as possible to the car behind you then drive forward with the steering wheel steady and adjust What is the distance from the curb should your car be when completing the maneuver of parallel parking? 6-18 inches from the curb The zone locations a driver uses are also call...

(2021) proposed a new active clearance measurement (AGM) signal to help the off-lane driver adjust the distance between the off-lane driver and the vehicle ahead when approaching the highway ramp with incoming traffic. AGM effectively affected the driver's behavior in the right lane so that ...
following strategy to address the SOTIF problems like this. By analyzing thehistorical data, the motion behavior of the preceding vehicle when SOTIF events happen is predicted based on the improved Markov model. Then, the observation and expectation models of the vehicular distance are designed based...
