CE Quiz 61

Fixed delays in highways is due to

If the traffic density on a highway is 100 veh/km, the average spacing /space headway (in m) is:

If the stopping side distance and average length of the vehicle is 18m and 6m. The theoretical max capacity(vph) of a traffic lane at a speed of 25m/s.

Which of the following statement is correct for traffic Engineering

What will be the max flow in VPH for relation v=55 - 0.44k,where v is speed in kmph and k isdensity in vpkm

According to Greenshield, the relationship between speed and density is

If the free mean speed and jam density of a road is found to be 90 kmph and 80 vpkm, the maximum flow in vph that can be expected in this road is:

If the sum of ratios of normal flows to saturation flows of two directional traffic flow is 0.80 and the lost time per cycle is 10 seconds, the optimum cycle length in seconds as per IRC design is:

The annual average daily traffic in a proposed highway at last count is 300 CVD. The annual rate of growth of traffic is 5%. If the road is to be completed in two years, the initial traffic in the road after construction will be:

Find the effective green time of a traffic signal, where lost time due to starting delay is 2 seconds, actual green time is 19 seconds and amber time is 3 seconds.
