Highway Safety

Proper highway safety refers to the methods or rules that prevent highway travelers from being killed or severely injured. Proper highway safety measures help to protect motorists, cyclists, pedestrians, passengers on public transport, and so on.

Question 2 Because the new travel time rate (TTR) from the additional traffic (e.g., 300vph) exceeds the minimum acceptable local standard of 2.0 min/mile, it is proposed to increase the road capacity by 900vph/lane by adding one lane in each direction. Calculate the new travel time rate and traffic volume using: a. The traditional method of traffic impact analysis, and b. The above-mentioned pivot point analysis method. c. Compare the results of the two methods and comment on their significance.

A travel time study conducted on I-77 in the Charlotte metropolitan area shows that it takes 45 minutes to travel from exit 1 to exit 28 (northbound direction) during evening peak hours. Contrarily, it only takes 29 minutes to travel the same distance during evening off-peak hours. Calculate travel rate, delay rate, relative delay rate, and delay ratio for this 28-mile section. Calculate the total vehicle delay and total person delay if the average traffic volume is 3,600 vehicles and average vehicle occupancy is 1.2 during the peak hour. Also, calculate the vehicle miles traveled (VMT) and person miles traveled (PMT).

You are designing a freeway as a passenger-car-only facility, and with ideal roadway characteristics. It is estimated that the freeway will have a traffic demand of 75,000 vehicles per day, a peak-hour factor of 0.88, and a directional distribution of 0.65. day. It is estimated that the freeway will have a free flow speed of 70mi/h. Determine the number of lanes (both directions) required to provide at least LOS D using the 60th highest annual hourly volume. Use k =0.11.
