(15 points) 7.Traffic flows at 2,000 veh/hr in the direction of increasing z on a one-directional road. At location x-0 the road narrows from 2 to I lanes. We assume that a flow-density curve, triangular in shape, defines the possible traffic states at all points in time-space. The following parameters apply to the l lane section: free flow speed 80 km/hr, jam density k.-75 veh km, and critical density k, 25 veh/km. a. Plot the flow vs. density...

QUESTION THREE On an urban highway, the relationship between vehicle speed and density can be represented by the Greenburg Model as the data in Table 3.1. Due to the roadwork on this highway, the width of both traffic lanes is narrowed and a bottleneck to traffic flow forms. The maximum flow on the unobstructed highway is 5000 vehicles per hour whilst on the section under repair the maximum flow is 4000 vehicles per hour. When the traffic flow approaching the...
