Calculate the location where the pilot cars will begin the RSM and the speed at which the pilot cars will travel to accommodate the needed time to complete the work within 20 minutes. Perform a RSM by using one pilot car for each lane to be slowed. Use only pilot cars to control the flow of traffic on the freeway. Use one additional pilot car as a chase vehicle to follow the last free-flowing vehicle ahead of the blockade. The pilot cars shall enter the roadway, form a moving blockade, and reduce traffic speeds to create a gap in traffic to accomplish the work without completely stopping traffic. When using the RSM, place a PCMS a minimum of 2,500 feet in advance of each point where the pilot cars enter the freeway. Place flagger(s), accompanied by appropriate devices and signing, at the terminal of all closed on-ramps within the controlled delay area. Establish and utilize radio communications to adjust the speed of the blockade, as necessary. Maintain radio communications at all times among the pilot cars, flaggers, and the construction crew. The Contractor may begin work immediately after the chase vehicle has passed the work area. If the work within the work area is not completed when the moving blockade reaches it, immediately cease all work except what is necessary to clear the roadway and reopen the roadway to traffic. Succeeding RSM will not be permitted until traffic clears from preceding RSM. SP225 (06-26-08) (This Section requires SP440 when temporary traffic signals are required.)
