A traffic signal control is being designed for a four-leg intersection on a divided highway with the characteristics shown in the table below. Assuming the average vehicle length L is 6m, Determine an appropriate length of the yellow interval for each approach and how you will provide it.

Problem-Traffic Engg. A two-phase signalized intersection is designed with a cycle time of 120 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)
A two-phase signalized intersection is designed with a cycle time of 100 s. The amber and red times for each phase are 4 s and 50 s, respectively. If the total lost time per phase due to start-up and clearance is 2 s, the effective green time of each phase is s. (in integer)
Compute the average approach delay per cycle, given the saturation flow rate of 2400 veh/h and is allocated 24 seconds of effective green in an 80-second signal cycle. Flow at the approach is 500 veh/h. Assume the traffic flow accounts for the peak 15-min period and that there is no initial queue at the start of the analysis period.

7.12 The saturation flow rate of an approach to a pretimed signal is 6000 veh/h. The signal has a 60-second cycle with 20 seconds of effective red allocated to the approach. At the beginning of an effective red (with no vehicles remaining in the queue from a previous cycle), vehicles start arriving at a rate v(t) = 0.4 +0.01t + 0.00057+² (where v(t)) is in vehicles per second and t is the number of seconds from the beginning of the cycle). 30 seconds into the cycle the arrival rate remains constant at its 30-second level and stays at that rate until the end of the cycle. What is the total vehicle delay over the cycle (in vehicle- seconds), assuming D/D/1 queuing?
The essential five methods used to control conflicting streams of vehicles at intersection are : channelization, stop signs, all-way stop sign, and traffic signal. : а. bus stops O b. lighting С. yield signs O d. parking
10. For the intersection shown below draw a 3-phase traffic signal operation.
Question- Topic: Traffic Studies on Flow, Speed, Travel Time, Volume and Capacity The lost time due to starting delay on a traffic signal approach is noted to be 3 sec, the actual time is 20sec and the amber time is 3sec. How much is the effective green time? green
