An incident that occurs on a particular highway results in traffic incurring an average delay of one hour per vehicle. An estimated 2,000 vehicles are impacted by the incident. If the distribution of traffic is comprised of 5% five-axle trucks, 2% three-axle trucks, 4% six-tire trucks, 2% four-tire trucks, 4% medium auto for business purposes, 3% small auto for business purposes, and the remainder are automobiles for personal purposes, what is the value of the total delay incurred by the traffic.

Question

What will be an ideal response?

Answer 1

Determine the traffic volume for each vehicle type:
Five axle trucks: 5% × 2000 = 100
Three axle trucks: 2% × 2000 = 40
Six tire trucks: 4% × 2000 = 80
Four tire trucks: 2% × 2000 = 40
Medium auto for business purposes: 4% × 2000 = 80
Small auto for business purposes: 3% × 2000 = 60
Small auto for personal purposes: 80% × 2000 = 1600
Select the value of one hour of travel time from Table 13.2 and multiply these
values by the traffic volumes in each vehicle type category.
Five axle trucks: $46.83 × 100 = $4,683.00
Three axle trucks: $40.07 × 40 = $1,602.80
Six tire trucks: $37.02 × 80 = $2,961.60
Four tire trucks: $22.37 × 40 = $894.80
Medium auto for business purposes: $41.96 × 80 = $3,356.80
Small auto for business purposes: $41.52 × 60 = $2,491.20
Small auto for personal purposes: $18.95 × 1600 = $30,320.00
Therefore, the value of total delay is $46,310.20 (the sum of the values for each
vehicle type category.
