(1) Parking prohibitions and turn prohibitions shall be warranted if: (a) 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) to prevent facility conflicts with maintenance; or (c) for time limit restrictions or loading zones.
