1. A developer wants to provide access to a new building from a driveway placed 1000 ft upstream of a busy intersection. He is concerned that queues developing during the red phase of the signal at the intersection will block access. If the speed on the approach averages 35 mi/h, the density is 50 veh/mi, and the red phase is 20 sec, determine if the driveway will be affected. Assume that the traffic flow has a jam density of 110 veh/mi and can be described by the Greenshields model

Expert Solution
Step 1

Given:-

Building access is 1000 ft upstream of intersection

Average approach speed = 35 mi/h

Density = 50 veh/mi

Red phase = 20 sec

Jam density = 110 veh/mi

To find:-

Its required to check if the driveway is affected
