Delay study (Cost of delay)

For 15 minutes, service flow rate = 329 PCU/hr

Assuming same flow condition prevailed and 10-11 am was the peak hour

For 1 hour total service flow rate = (329 * 4) = 1316 PCU/hr

This 1 hour is 15% of total Average daily traffic.

So, ADT = (1316/0.15) = 8773 PCU/hr

From pie chart composition, it was found that light vehicle was 42%

So average daily light vehicle = 8773*0.42= 3684.66 PCU/hr

Assuming Average duration in free flow condition for light vehicle =100 Seconds,

Bus= 150 seconds, CNG= 160 seconds and Motorcycle= 200 seconds

Delay time= dT1-dT2= 160.80-100=60.8 seconds/ light vehicle

Delay time of light vehicles per day= 60.8*3684.66=224027.328 seconds= 62.22 hours

From data provided, light vehicle occupancy= 2.1

Passenger time value (per passenger hour) = 62.22* 2.1* 20 = 2613.24 taka
