A Macroscopic Traffic Model Based on the Safe Velocity at Transitions

The increasing volume of vehicles on the road has had a significant impact traffic flow. Congestion in urban areas is now major concern. To mitigate congestion, an accurate model required which based realistic dynamics. A new proposed conservation law considers dynamics at transitions. Traffic alignment to forward conditions affected by time and distance between vehicles. Thus, well-known Lighthill, Whitham, Richards (LWR) modified account for behavior during alignment. inhomogeneous flow transitions can be used characterize evolution. performance compared with LWR using Greenshields Underwood target velocity distributions. These models are evaluated Godunov technique numerical stability guaranteed considering Courant, Friedrich, Lewy (CFL) condition. results obtained show that characterizes more realistically, thus provide better insight into use controlling congestion pollution levels, improving public safety.
