Travel speed is always the key parameter in both the traffic model and the emission model,so vehicle emissions intensity at a given travel speed is well known among public,but there are several proble
A theoretical model of a ground-track-vehicle coupled system is established to study the vibration of a layered transversely isotropic(TI)saturated ground from vehicles generated by vertical track irr
This paper focuses on analysing and quantifying the impact of adverse weather and road surface conditions on average traffic speed of an urban freeway in Des Moines,Iowa,US.The detailed traffic,weathe
A comparison of multi-states crash distribution is proposed to summary the major crash types among states and provide feasible countermeasures to each major crash type.Crash Analysis are currently pre
