On-street parking facilities may be designed with the parking bays parallel to the curb or
inclined to the curb Figure below shows the angles of inclination commonly used for
curb parking and the associated dimensions for automobile parking, It can be seen that
the number of parking bays that can be fitted along a given iength of curb increases as the
angle of inclination increases up to 90 degree The higher the inclination angle, s however, the
greater the encroachment of the parking bays on the traveling pavement of the highway
Parking bays inclined at angles to the curb severely interfere with the movement of traffic
on the highway, with the result that crash rates tend to be higher on sections of roads with
angle parking than on those with parallel parking It should be noted that the dimensions
given in Figure below are for automobiles When parking bays are to be provided for trucks
and other types of vehicles, the dimensions should be determined on the basis of the
dimensions of the specific vehicle being considered.
