A well-designed signalized intersection is one in which the
vehicales arriving at an intersection from one of the approach roads follow the poisson distribution. The mean rate of arrival is 900 vehicales per hour. If a gap is defined as the time difference between two successive vehicale arrivals (with vehicales assumed to be points), the probability (up to four decimal places) that the gap is greater than 8 seconds is _______________
The saftey within a roundabout and the efficency of a roundabout can be increased, respectively, by
The following statements are made related to the lengths of turning lanes at signalized intersections:
(i) 1.5 times the average number of vehicles (by vehicle type) that would store in turning lane per cycle during the peak hour (ii) 2 times the average number of vehicles (by vehicle type) that would store in turning lane per cycle during the peak hour (iii) Average number of vehicles (by vehicle type) that would store in the adjacent through lane per cycle during the peak hour (iv) Average number of vehicles (by vehicle type) that would store in all lanes per cycle during the peak hour
As per the IRC recommendations, the correct choice for design length of storage lanes is
