A two-lane rural highway, four-leg intersection will have its stop control replaced by a signal control. Compute the expected average total crash frequency (all types, all severities) after the change for the following conditions:   Expected average crash frequency before change: 23 total crashes/yr AADT on minor road: 1500 veh/day  AADT on major road: 5000 veh/day   Please show all work and formulas used. Thanks! Submitting this again this the last person didn't even answer the question at all. Not sure what...

1. On one approach of an intersection with fixed time traffic signal, vehicles arrival rate is 600 vehicles per hour. The effective green time for this approach is 30 seconds, the saturation flow of this approach is 1800 vehicles per hour and the cycle time of the intersection is 80 seconds. a. Evaluate the performance of the signal design i.e. will all vehicles clear during the green time? b. Recommend the changes to the green time for this approach to...

DOT wants to install a traffic signal at a dangerous intersection on US-51. The traffic signal will cost $450,000. Based on historical data, it will eliminate, on average, one fatal accident every 10 years, but will cause 5 additional minor accidents every year. The standard cost assigned to fatal accidents is $12,300,000 and the cost assigned to minor accidents is $160,000 each. At an interest rate of 4% per year, does the B/C ratio justify the cost of the signal?...

A traffic signal on the four-leg signalized intersection is designed based on the information below. Please answer the following questions. The startup lost time per phase is 2.0 seconds, and the clearance lost time per phase is 1.5 seconds. The deceleration rate of the vehicles is 3.4 m/s2, and the average length of the vehicles is 6.0 m. The lane width of normal lane is 3.3 m, and the turn bay width is 2.8 m. Please ignore the median width...

Traffic counts and signal timing data were collected for the intersection of Sand Creek Road and Wolf Road. The intersection is signalized. The collected data show that, for a particular cycle, vehicles on the through lane of the SB of Sand Creek Road had the following arrival headway pattern (counted from the start of the red time of the cycle): – 2.5 seconds for the first 10 seconds – 2 seconds for the time period of 44 ‐ 50 seconds,...
