Simulation and Analysis of the Buffer Function of Freeway Greening on Out-of-Control Vehicles
Freeway greening and traffic safety have been arousing more and more attention. The purpose of this study is to investigate the role of flexible green planting in buffering out-of-control vehicles. The stopping distances of vehicle rushing into greening were tested on eight groups of initial speeds range from 5 km/h to 40 km/h in green belt, and a simplified mathematical model was built to simulate the buffering process. The results indicated that the greening plants have certain buffering effect on vehicles and alleviate the crash damage within 30 m of the stopping distance for the vehicles under 40 km/h, while the simplified mathematical model could reflect the buffering process of the plants actually by simulating the speed attenuation process. It was found that the two types of resistance produced by the plants, i.e. counterforce of plant trunks and friction of branches and leaves are the major factors during the vehicle deceleration.
