Initial placement of each barricade is paid for as a contract item at the time of placement. In urban and suburban areas with high vehicular traffic volumes, place the signs at intersections. For construction projects awarded after June 30, 2021, all records are to be stored electronically in the Caltrans Falcon electronic document management system (FalconDMS). The traffic control system for flaggers should follow Sheet T13 of the. The transition should be accessed before such features. Confirm that the contractors closure requests comply with the closure charts. When the work has safely progressed beyond the supplemental taper, remove the upstream taper and tangent. Consider suspending work for the next shift until a written plan is provided to address future public safety. CHP Careers. The Department has standardized its road and lane closure reporting into a statewide Lane Closure System (LCS). If you authorize the devices for use, record the authorization in the daily reports. Section 12, Temporary Traffic Control, directs the contractors attention to the. 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. Refer to Section 7-1.04, Public Safety, of the. Verify removal of any temporary delineation that conflicts with any subsequent or new traffic pattern for the area. The ideal transition is on a horizontal tangent with a slightly rising grade at the end of a level approach. If this equality is not possible, confirm that the design speed differential is no more than 10 mph. While the Caltrans' charts did not explicitly dictate that a contractor must perform work during nighttime hours, the charts functionally required that any work requiring a lane closure could only be performed at night. Do not allow the use of power from private parties to power the temporary flashing beacon system. When estimating COZEEP hours, take the following CHP operating policies into account: The detail estimate will show the initial funding level provided for COZEEP as supplemental funds for state-furnished materials and services. Dated photographs or video recordings, particularly of points of transition, may be especially valuable. 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. This notification allows Caltrans to coordinate work within the highway corridor. Municipal Code. If the equipment is not available, make other arrangements as soon as possible. Verify visibility and legibility requirements. 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. TMP strategies are designed to maintain additional delays below this maximum threshold, that is, less than 15 or 20 minutes. Inspect crash cushion modules to confirm they comply with the specification and manufacturer requirements. The contractor should develop a plan for handling emergencies and emergency vehicles in the control zone. Include these considerations for conditions requiring minor changes in the field: The following guidelines apply to crossover transitions: For temporary modifications of existing ramps, review acceleration and deceleration lanes. All closure information is continually updated and subject to change. Visualize what effects changing conditions of visibility and lighting will create. SignsReview sign line of sight visibility and verify it complies with Section 12-3.11, Construction Area Signs, of the, Vertical and horizontal curvesVerify tapers are visible for their entire length to approaching traffic. Capital projectsif insufficient funds are available in both supplemental work funds and contingency funds, propose a fund request. As funding and operations allow, consider providing COZEEP for the following situations: Generally, COZEEP is not necessary when only one lane is closed on freeways with four or more lanes in the same direction of travel. SEE NOTE 2 END ROAD WORK G20-2 B 100' 10-20-10 48" x 24" 237 Establish reduced regulatory speed limits in accordance with procedures in the. Verify the base is shaped to prevent delineators from rolling if stuck by vehicles. Work zone activities can disrupt the publics mobility and access. This will speed the placing of closures and allow for a more consistent taper alignment. Key personnel involved in traffic control have responsibilities as follows.

Consideration for worker safety and the safe movement of traffic through work zones starts with planning. Describe the work by length, width, and unit of measure conforming to the appropriate progress pay items. Remember that the motorist has no knowledge of the traffic control plan and is entirely dependent on the system for warning and guidance. 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. During construction, district construction directs the implementation of TMP elements that are part of the contract or encroachment permit. The contract item price also includes the costs of work necessary to restore channelizers damaged by public traffic. If the contractor fails to reopen the highway according to the closure charts, suspend work and request a detailed written construction contingency plan demonstrating that the highway will be opened as soon as possible. Do not allow the contractor to close two adjacent ramps in the same direction of travel unless necessary because of the operation or project conditions. The contractor bears costs and expenses for additional support from the CHP, and Caltrans deducts associated costs from monies due the contractor. You may also consult the district Traffic Operations office. Be aware that reductions in the width or number of lanes affect the capacity and flow of traffic. Verify barricade construction complies with Section 12-3.10, Barricades, of the Standard Specifications and sheet A73C, "Delineators, Channelizers, and Barricades," of the Standard Plans.

Initiate and obtain CHP sign-off of Form CEM-2101, COZEEP Daily Report. At the end of each day, report to the district COZEEP coordinator the COZEEP services used during that week. Confirm the sign is placed where it is most visible to approaching motorists. Verify that traffic handling devices meet the visibility and legibility requirements. Time and mileage are based on officers starting and stopping times at their reporting station and include travel to and from the project. The design and construction at the contractors expense, when the contractors means and methods require the closure of an existing pedestrian route. If automated flagger assistance devices (AFAD) bid item is not shown on the bid item list, providing AFAD is change order work. Cold storms bringing wind, rain and low-elevation snow heavy at times are forecast through early March. Follow the districts instructions for distributing news releases. In addition to required openings through falsework, provide accessible pedestrian facilities during pile driving, footing, wall, and other bridge construction activities where an accessible route was available before construction began. Any part of the project within the limits stated in the order becomes a legal speed zone when signs are placed. District Construction should request an impact study for proposed prolonged ramp closures not formally considered in the planning or design phase. Evaluate the COZEEP use criteria for complete highway closures and nighttime closures of one or more lanes on multilane highways. If the contractor is to place the traffic control system repeatedly in the same place, the contractor can request to mark on the shoulder the locations of advance warning signs, cones, and drums. Discuss the contingency plan at the project partnering or preconstruction meeting. Achieving this transition is worthwhile, even though it may extend the traffic control system farther than the minimum necessary to clear the work zone. Consider use of changeable message signs in advance of the work, in addition to the signs and warning devices shown on the plans for traffic control systems. The reviewer should determine that the plan can be implemented and that it adequately facilitates the movement of trafficincluding bicycles, motorcycles, and pedestrians. Avoid blinding drivers in approaching vehicles when adequately lighting work areas. In general, closures on two-lane highways and daytime closures on multi-lane highways do not require COZEEP. The request may be processed under the G-12 process or require a California Transportation Commission supplemental vote. Determine the methods and equipment the contractor will use for closing lanes, ramps, and roadways, and for flagging and controlling one-way traffic. Also confirm it in writing using Form CEM-2103, COZEEP/MAZEEP Cancellation Form. Once contact is made, the CHP coordinator will return the completed cancellation form. Refer to Part 6, Chapter 6D, "Pedestrian and Worker Safety," of the California MUTCD.
