Type of intersections and Choice
From a design aspect, intersections can also be divided according to whether they are uncontrolled, priority (stop give way), space sharing (round about), time-sharing(traffic signal controlled), or grade separated (interchanges). The four categories given in IRC code (special publication, 1994) are:
Uncontrolled at-grade:These are the intersections between any two roads with relatively lower volume of traffic and traffic of neither road has precedence over the other.
Priority control:There is theoretically no delay occurring on the major road and vehicles on the minor road are controlled by “GIVE WAY” or “STOP” signs.
Time separated /Signalized intersection at grade:These are widely seen road intersection with traffic signals.
Space separated/Grade separated intersection:These intersections facilitates movement at different levels for vehicles and pedestrians. Example of such type include intersections with flyovers, under pass
