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?...

Design an automatic traffic light control signal for a road square using 1MHz internal oscillator of PIC16F887. Each traffic light must consist of three (Red, Yellow, Green) lights. Use proteus for implementation. Your code must use four light signals installed on each road connecting to square. in word program form.(text and diagram )

A traffic signal has a cycle length of 90 seconds. For the travel direction of interest: (1) Green Time = 60 seconds; (2) Red Time = 30 seconds; (3) Arrival Rate = 30 veh/min; (4) Saturation Flow (i.e. the queue discharge rate) = 1 veh/sec. a) Calculate the total delay (veh*s) for the travel direction of interest. b) What is the maximum queue size (veh)?

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,...
