Prohibit the use of traffic cones that have been damaged or coated with asphalt or other substances that prevent the cones from functioning as intended. Depending on the complexity of the work or the magnitude of anticipated effects, a TMP may provide closure charts, standard special provisions for maintaining traffic, traffic control plans, andfor major projectsa separate comprehensive report. Caltrans can enforce contractor compliance with closure pickup deadlines in two ways: Caltrans can order a contractor to pick up a closure early if traffic delays become significant because of a project incident or activities outside the project area. Verify the signs are properly aimed at approaching traffic. Advisory speeds are not enforceable by the CHP. Unless the contractor can provide a reasonably safe route that does not involve crossing the roadway, use appropriate advance signing to direct pedestrians to cross to the opposite side of the roadway. Design for the speed that vehicles will travel. The cost estimate used in the plans, specifications, and estimate is based on the expected number of events needing COZEEP identified during project development. Complete training in one sitting. Automated flagger assistance devices (AFAD) can be used in place of flagger to remove workers from the roadway to improve worker safety from traffic. Scheduled Dates: 06/13/2022 to 01/16/2023.
