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.

It is known that the capacity is 3800 veh/h and the jam density is 225 veh/mi. What is the space-mean speed of the traffic at capacity, and what is the free-flow speed? if chart or graph was used please attaxch below and explain how its used
A Four Lane freeway is located on rolling terrain with a free flow speed of 70 mph,12ft lanes, and no lateral obstructions within 8 ft of the pavement edges. the traffic stream consists of cars, buses and large trucks (no recreational vehicles) . A weekend directional peak hour volume of 1800 vehicles (*regular users*)is observed ,with 700 arriving in the mostly congested 15 minutes period . if a level of service no worse than C is required ,determine the maximum number of large trucks and buses that can be present in the peak hour traffic stream.. Dislike for wrong answers
Problem 2. Consider a freeway section with three lanes in each direction and with a length of 1.25mi (2km) and a +5% grade. In this freeway, the directional peak-hour volume is 3,800 veh/h, from which 76 are trucks and 152 are transit buses. The maximum 15-min volume within the hour of analysis is 1,055 vehicles. The lane widths are 12 ft (3.6m), and shoulder widths are 10 ft (3.1m). There are 2 exit ramps and 1 entrance ramp in the 3 miles in the upstream section and 1 exit ramp and 2 entrance ramp in the 3 miles in the downstream section (consider the same ramp density if using international (km) units). All transit buses will be removed from traffic since the transit service will be replaced by a commuter rail service. However, by removing buses, new additional passage car demand is expected. It is estimated that for each removed bus, 7 new passenger cars will be added to the original traffic volume of 3,800 veh/h. Question: Determine the change in speed and traffic density before…

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 free-flow speed of 70 mi/h, a traffic stream of primarily commuters, a peak-hour factor of 0.88, and a directional distribution of 0.65. Determine the number of lanes (both directions) required to provide at least LOS C using the 40th highest annual hourly volume (K = 0.116). A 6 B) 4 c) 10 D) 8
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).

A proposed improvement will widen a two-lane rural highway from 9-ft-wide (per lane) to 11-ft-wide (per lane) if the highway has an AADT of 2100 veh/day. If there are an average of 25 crashes per year on the segment proposed for improvement, and 67% of the crashes are of the type targeted by the improvement, estimate the expected number of crashes (per year) after the improvement is constructed.

Tubibi Highway is a Class II Two-lane highway that is considered a level terrain. Based on the data, 1,631 passenger cars travel on average per hour for both directions with a directional split of 50/50. A maximum of 388 passenger cars is recorded within a 15-min time segment of the peak hour. The traffic stream contains 2% large trucks, 3% buses, and 3% recreational vehicles. Determine the opposing direction flow rate in pc/hr. Answer in two decimal places. 2,953.65 776 margin of error +/- 0.5
