An engineering investigation indicates that such prohibitions will improve safe traffic operating conditions; or

(b)

An engineering investigation indicates that such prohibitions are necessary to increase the capacity of the roadway or to otherwise expedite the movement of traffic.

(c)

The engineering investigation will include a review and analysis of the past accident history, a study of the traffic volumes, patterns and turning movements when appropriate. A field investigation of the physical conditions will be made when required.

(2)

Parking prohibitions shall be warranted if an engineering investigation indicates that such parking prohibitions are necessary:

(a)

to prevent the imminent damage to the facility. Where parked vehicles could damaged the pavement surface; or

(b)
