The objective of traffic control is to provide for worker protection and the safe passage of public trafficincluding bicycles, motorcycles, and pedestriansthrough and around the work zone with as little inconvenience and delay as possible. The following guidelines are intended only to guide engineering judgment and ingenuity: Following are guidelines for the design of roadways carrying traffic through work zones. Periodic project safety reviews should note deficient areas and provide recommendations for the contractor to correct those deficiencies. Construction signs should be covered or removed whenever they no longer serve a purpose. For example, if the number of lanes is reduced and the direction changed, complete the lane drop before starting the alignment change. At the end of the shift, the senior CHP officer onsite should estimate travel time and mileage for each officer from the project site to the CHP office. Cold storms bringing wind, rain and low-elevation snow heavy at times are forecast through early March. Do not allow the use of a damaged impact attenuator vehicle. Strategies that may result in a net reduction of overall delay for motorists include full facility closures, extended weekend closures, continuous weekday closures, A+B contract specifications, and performance-based, traffic-handling specifications. Major lane closuresthose expected to result in significant traffic effects despite the implementation of TMPs. Operation work schedule with a timeline set at 20-minute intervals. Require at all times the presence on the job of personnel representing the contractor who are capable of and empowered to make decisions quickly if the need arises. Provide protective overhead covering as necessary to protect from falling objects and dripping from overhead structures. Verify that portable flashing beacons comply with the requirements in Section 12-3.31, "Portable Flashing Beacons," of the Standard Specifications. Review the requests to avoid oversights and overbooking. Use an appropriate material, such as asphalt concrete, for the surface of all roadways and detours, except very temporary or minor facilities. The contractor bears costs and expenses for additional support from the CHP, and Caltrans deducts associated costs from monies due the contractor. How the contractor will meet the projected rates for material delivery to the job site. Caltrans does not pay for providing the TPAR when the pedestrian route closure is the result of contractors means and methods. Obtain a copy of the manufacturers instructions for the portable transverse rumble strips. If the opening has a drop off behind it that might present a hazard to the public, document in the resident engineers daily report an exception to the Standard Plans note and have the contractor close the gap for public safety purposes. Verify that the line of sight visibility in the field meets sight distance standards. Flash flooding and mudslides have closed some stretches on I- 5 and SR-58. During the inspection process, check that all contractor-installed finished elements comply with dimensions and installation requirements. Connect closures by extending the tangents. Directing the contractor to move the portable flashing beacon after initial placement is change order work. Whenever possible, allow traffic to have continued full use of the existing facilities. This section provides guidelines for inspecting temporary traffic control devices in construction areas. Verify portable flashing beacons operate according to the specifications. The traffic control plan should be appropriate for anticipated conditions that may occur during construction. If the equipment, materials, or workers are not onsite, the contingency plan specifies the method of mobilizing these items and personnel, and the time required to complete the mobilization. End-of-queue management is desirable at locations where traffic queues are anticipated. Verify no-passing zone signs are removed when no longer required. Any contractor requests for COZEEP that are denied by the resident engineer should be in writing to the contractor stating the reasons for denial of the COZEEP support. The change order must clearly state there will be adjustment on the traffic control system item by reason of this change. the lane closure unless the end of work area is obvious or A G20-2 "END ROAD WORK" sign shall be placed at the end of lane closure during hours of darkness.

Be aware that reductions in the width or number of lanes affect the capacity and flow of traffic. COZEEP is not a baseline measurean important fact when resources are limited and CHP personnel may not be available when requested. Avoid placing entering transitions on or just beyond horizontal curves or the crest of a summit vertical. Click on any marker to get project details as of March 1, 2023. Ask the contractor to replace channelizers that are displaced or fail to remain in an upright position. Motorists who are forewarned of construction conditions may be more tolerant of delay and inconvenience and probably will be more alert and responsive to work zone traffic control. Click on the Nextbutton at the bottom right to go to the next slide. Samples of activities that may require a contingency plan: A construction contingency plan describes: The contractor verifies or updates the contingency plan at the same time as submitting the written schedule of planned closures. The contract item price also includes the costs of work necessary to restore channelizers damaged by public traffic. The statewide master agreement for COZEEP requires that all Caltrans requests for support be received by the supporting CHP area office during normal working hours and at least 72 hours before the time needed. Then remove the devices and signs in the reverse order of placement. Take the following steps before work begins: Discuss any flagging operation with the contractor before the operation begins. Caltrans is working to clear the roads in order to reopen them. Generally such projects are intermediate type projects that cause minimal/moderate work zone impacts. CHP invoices will include monthly charges for services provided. The CHIN incident layer is updated every 1 minute. All drums should use the same type and brand of retroreflective sheeting. All closure information is continually updated and subject to change. Check the exposed surfaces of Type K temporary railing to verify they have received a fresh coat of white paint before initial placement on the job. Verify all threaded rods or dowels are removed and the area is restored to its previous condition or constructed to its planned condition after removal of Type K temporary railing.

The design phase of a project considers accommodating pedestrians through or around the work zone. Users include motorists, bicyclists, and pedestrians within the highway, including persons with disabilities, defined by the Americans with Disabilities Act of 1990 (ADA). The project engineer should consult with the resident engineer to determine which specific construction operations should use COZEEP and use that as the basis of the initial funding. Verify the lights are not glaring into approaching traffic, especially truck traffic. Verify telescoping flag trees maintain an upright position when being used. After placing components of stationary closures, the contractor may place the impact attenuator vehicle in advance of the work area to protect workers and traffic. If the blunt end is within 8 feet, appropriate approved crash cushion protection other than sand filled modules should be provided. The contingency action plans should include detailed operations undertaken in case a major activity passes the late-finish milestone. Consider sight distance for drivers because of temporary features such as falsework impeding view of traffic signal systems. Make the environment like the approach highway. The Angeles FOREST Highway is under our jurisdiction and closures for this highway can be found on our website. Perform additional reviews periodically throughout the construction project, since changes may affect the facilitys effectiveness. Verify the contractor completely installs the traffic control system before commencing work. Also refer to Section 2-2, Traffic, of this manual, which provides guidance and a general overview of providing a safe and convenient passage of public traffic through the construction area and is complementary to this section. Verify that Category 3 temporary traffic control devices are on the Authorized Material List for Highway Safety Features. Check that the attenuator meets the test level requirement for the posted speed limit. Containment may require modestly increasing the spacing between signs or require the placing of additional signs. Coordination with the district COZEEP coordinator is needed to determine local CHP policies. Contact the district traffic manager for assistance with either of these tasks. During the preconstruction conference, discuss: https://dot.ca.gov/programs/construction/forms. Impact attenuator vehicles are paid for as part of the contract item for the traffic control system. Consider placing supplemental tapers within an existing closure. Visualize what effects changing conditions of visibility and lighting will create. The following guidelines apply to the color and texture of pavement surfacing materials: The following guidelines apply to speed zones: Frequently, special provisions restrict work on the existing traveled way to a specified period at night. Speed management is desirable at locations such as rural freeways and expressways where traffic has been flowing in a high-speed, free-flow way for a significant period before encountering the work zone. If the contractor cannot address the traffic safety issue and it is not safe to suspend the work, request that the contractor take all steps necessary to provide for traffic safety and allow only the work to continue that had started at the time the issue was recognized.
