Abstract

To research the numerical relationship between headway and speed, field data of car-following is gathered by vehicles equipped with high precision GPS, and a Modified Optimal Velocity model (M-OVM for short) is built based on the field data. The original OVM and the M-OVM are calibrated and extended to the macroscopic parameters, the result shows that the M-OVM can describe the relationship of traffic parameters with a higher accuracy. Furthermore, simulations are conducted to analyze the characteristics of the car-following model with the M-OVM, the result shows that the M-OVM can improve the stability of the car-following model.
