The 20-year projection of annual average daily traffic of a two-way roadway is 36.500 vehicles. The road serves as a highway between a residential area and a business area and the expected directional distribution factor is D=0.6. The 30th peak hour factor for the roadway is K=0.15. During an hourly vehicle count, the following values were registered: 1st 15 minutes: 200 cars, 2nd 15 minutes: 130 cars, 3rd 15 minute 230 cars, 4th 15 minutes. 180 cars. Esti

The 20-year projection of annual average daily traffic of a two-way roadway is 36.500 vehicles. The
road serves as a highway between a residential area and a business area and the expected directional
distribution factor is D=0.6. The 30th peak hour factor for the roadway is K=0.15. During an hourly vehicle
count, the following values were registered: 1st 15 minutes: 200 cars, 2nd 15 minutes: 130 cars, 3rd 15
minute 230 cars, 4th 15 minutes. 180 cars. Estimate the peak hour factor . What is the design
directional hourly volume for this route?
