A car-following model with real-time road conditions and numerical tests

A New Calibration Method for the Real-Time Calculation of Dynamic Safety Following Distance under Railway Moving Block System

“…where 1 is the period of the preceding decelerating from the initial velocity train when it adopts emergency braking and can be gotten by (2). In a similar way, we can get the fitting function of 1 corresponding to its own various initial velocities when the preceding train stops abruptly, as shown below.…”

“…Lamonde [1] proposed the criteria called "activity oriented ergonomics" for coordination at a distance design. In [2,3], Tang et al and Yang et al used the empirical data to calibrate the speed-headway function and proposed a car-following model to investigate the effects of real-time road condition on each vehicle's speed, acceleration, headway, fuel consumption, CO, HC, and NO X under uniform flow. The numerical results showed that under the smooth driving behavior the electric vehicle's battery life can be prolonged.…”

Dynamics of connected cruise control systems considering velocity changes with memory feedback

“…Recently driving behaviors have been seen to offer considerable potential method for reducing fuel consumptions and exhaust emissions [46]. The existing studies indicate that driving behaviors can affect drivers' fuel consumptions and exhaust emissions [47][48][49][50][51][52][53][54][55][56]. Wu et al [46] developed and validated a new fuel-economy optimization system to help drivers, especially new drivers learn how to manipulate pedals according to traffic and environmental situations and eventually form an eco-driving style.…”

“…Shi et al [51] studied the relation between the fuel consumptions and the stability of traffic flow simulated by several typical car-following models and found that minimizing the energy consumptions will depend crucially on the stability of the traffic flow simulated by the corresponding car-following model. Tang et al [54] incorporated the theories of the literature [50] into a car-following with consideration of real-time road conditions to study the impacts of the car-following behaviors considering real-time road conditions on fuel consumptions, CO, HC and NO X emissions and found that fuel consumptions and exhaust emissions are related to the stability of traffic flow. Therefore, it is very necessary to explore the impacts of multiple preceding cars' velocity changes with memory in the connected cruise control strategy on each car's fuel consumptions, CO, HC and NO X emissions under the traffic flow with a small initial perturbation.…”

A New Car-Following Model considering Driving Characteristics and Preceding Vehicle’s Acceleration

“…Furthermore, a number of new car-following models have been carried out based on FVD model. Tang et al [6,7] proposed a car-following model with the consideration of road conditions and vehicle communication on the basis of calibrated speed-headway function. Gong et al [8] put forward a new full velocity difference model considering 2 Journal of Advanced Transportation the asymmetry of the vehicle acceleration and deceleration process on the basis of FVD model.…”
