Design and explain an automatic transport parking system with the the following attributes.
a) maintaining count of vehicles enter in parking area.
Traffic data are collected between Point X and Y. Seven vehicles pass in Point X at intervals of 18, 17, 19, 28, 25, 22, and 24 sec respectively. The vehicle's speeds are 60, 50, 55, 58, 52, 49, and 30 kph respectively. Calculate the flow, density, time mean speed, and space mean speed. Determine also the length of the segment.
