Acceleration and deceleration behaviour of truck on Indian highway

Acceleration and deceleration (A/D) characteristics of vehicles are important for intersection design, acceleration deceleration lane design, traffic simulation modeling, vehicular emission modeling, instantaneous fuel consumption rate modeling, etc. Heterogeneous traffic stream consists of vehicles with wide variation in their physical dimensions, weight to power ratio and dynamic characteristics which affect their acceleration and deceleration behaviour in traffic streams. Trucks represent a major component of traffic composition on Indian highways. The present study aims to analyze the acceleration and deceleration behaviour of trucks which represent approximately 20% of the composition on Indian roads. Study was conducted on Nagpur-Mumbai Express Highway at Wardha, India. Drivers were asked to accelerate their vehicles from stop to their maximum speed and then to zero speed in the shortest time, and their speed profiles during acceleration and deceleration are collected using global positioning system at 1 second time intervals. Various A/D parameters like A/D distance, A/D time, mean and maximum A/D rates and speed at maximum A/D are reported in this study. A negative exponential model for acceleration and dual regime model for deceleration are proposed. Various statistical tools are used to validate the A/D models.
