Contractor will collect 7 day 24 hour traffic counts from Caltrans. Confirm the contractor provides a temporary pedestrian access route (TPAR) nearby, off the traveled way, when the construction activities require the closure of an existing pedestrian route. Refer to Section 4-1202C (1a), Lane Closure System, of this manual. Pay special attention to the aiming of the sign whenever solar-powered signs are used. Confirm the contractor places portable flashing beacons according to the plans and removes them from the traveled way at the end of each nights work. If the portable signal system is out of operation, the contractor must provide flaggers to control the traffic until the traffic signals are in operation. Stationary closures on the shoulder are 10-97 before placing the first cone after the last advance warning sign, and 10-98 after removing the last cone before the advance warning signs. 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. Imposing a 24-hour-a-day regulatory speed reduction can be difficult to justify and obtain approval for. Verify that the weight of the attenuator and the weight of the support truck are within the specified limits as shown on the Authorized Material List for Highway Safety Features. Design for the speed that vehicles will travel. Pay special attention to locations where vertical or horizontal curvature restricts the sight distance. Maintain written records of orders given and actions taken. Do not allow the use of nonretroreflective portable signs during hours of darkness. If new asphalt concrete joins existing asphalt concrete, the difference in texture and color between them creates a taper in the new traffic lane that may convey the wrong sense of direction, especially at night or in rain. 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. Obtain a sample of the type of portable delineator to be used on the project. The majority of Caltrans road projects (including this SR 41 example) fall under this category. PCMS can be used in place of an advance flagger to remove workers from the roadway to improve worker safety from traffic. Unknown time of reopening. District Construction should review the traffic control plan before the district submits the plans, specifications, and estimate to headquarters. Consult with the transportation management center before temporarily closing a ramp not previously scheduled through the LCS. Traffic Control Plans (TCP) and/or Detour Plans are reviewed and managed by the Right of Way Management Section and are required for all construction work within the road right of way which modifies vehicular, bicycle and/or pedestrian traffic patterns and are necessary to ensure the safe and efficient movement of traffic through construction In metropolitan areas, this type of warning may be feasible with cooperation of the transportation management center. Hand digging is required unless the location is free of underground utilities. 3. ALT ALT Verify that construction area signs are placed outside the traveled way, do not block or protrude more than 4 inches into bicycle and pedestrian routes, and comply with Americans with Disabilities Act requirements. Temporary full freeway closures of all lanes in the same direction of travel. Direct the contractor to remove any temporary pavement delineation that conflicts with the permanent pavement delineation. 8 CCR 1599, Flaggers, requires illuminating flagger stations during the hours of darkness and lighting should be in compliance with 8 CCR 1523, Illumination, for nighttime highway construction.

Refer to Section 4-1202C (1a), Lane Closure System, of this manual. Verify staking of railing according to sheet T3B of the Standard Plans. To enhance night visibility, delineate material, equipment, excavations, or obstructions 15 feet or more from the traveled way. Require the contractor to anchor bases of traffic cones that do not have enough size and weight to keep the cones in an upright position. Establishing continuity is especially necessary if previous traffic shifts have created confusing or conflicting diagonal joints and have eradicated pavement markings. Verify the contractor notifies and cooperates with local authorities wherever the local authorities regulate traffic. Compare the traffic control plan to site conditions. SEE NOTE 2 END ROAD WORK G20-2 B 100' 10-20-10 48" x 24" 237 Confirm that the contractors closure requests comply with the closure charts. 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. Verify that covers placed on sign panels completely block out any messages so that the messages cannot be seen day or night. During the project initiation or planning stage, Caltrans considers TMP measures with associated road user costs and additional construction costs to the fullest extent feasible. Do not hide the taper of a traffic control system behind a vertical or horizontal curve. For example, compensate for a sharper curve with solutions such as increased lane width or a clear recovery zone. Such conditions may alter the apparent pattern of the roadway and cause an eradicated line to appear to be a lane line. Similarly, certain striping operations require the operator to operate against live traffic because of clearances. Verify the contractor offsets the approach end of Type K temporary railing by 15 feet minimum from the edge of an open traffic lane, according to Section 7-1.04 Public Safety, of the Standard Specifications. The following COZEEP use criteria do not form an all-inclusive list. Report an Issue. The project engineer should include adequate COZEEP funds in the project estimate. Traffic control devices, equipment, and other construction materials and features should not protrude into the usable width of the sidewalk, temporary pathway, or other pedestrian facility. Midblock worksites should not cause pedestrians to skirt the worksite or make a midblock crossing. Do not allow the use of power from private parties to power the temporary signal system. Signs and other devices mounted lower than 7 feet above the temporary pedestrian pathway should not project more than 4 inches into accessible pedestrian facilities. Acts as the focal point for development and implementation of TMPs. Review sheet T3B of the Standard Plans for staking requirements. Questions?

Facilitates review and approval of TMP measures and planned lane closure requests. The contractors responsibility to provide written notice 5 days before closing an existing pedestrian route. Whenever possible, allow traffic to have continued full use of the existing facilities. The special provisions specify the minimum penalty of $1,000 for each 10 minutes and can exceed the minimum depending on the duration of the delay, traffic volumes, and the highway facility. The Butterfly Lane Pedestrian Undercrossing in Montecito is open following a major improvement project. For their application, review the current California Manual on Uniform Traffic Control Devices (California MUTCD). The last level of review will be the COZEEP statewide coordinator. The LCS will send the contractors employees a unique password by email after the accounts are created. Verify removal of any temporary delineation that conflicts with any subsequent or new traffic pattern for the area. Allow the use of paint only if the temporary traffic stripe is not required to be removed. Frequently, the only exception to an otherwise clean roadside is a localized situation such as a partially completed drainage structure or a pile of rubble. Initial placement of each barricade is paid for as a contract item at the time of placement. File formats include CSV, JSON, TXT and XML. Flash flooding and mudslides have closed some stretches on I- 5 and SR-58. The resident engineer should determine which contractor activities might use COZEEP support. Avoid traffic splits if possible. 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. For temporary pedestrian facilities, do the following: https://dot.ca.gov/programs/construction/safety-traffic, Chapter 1 - Caltrans Construction Organization, 2-204B State Representative on Projects Administered by Others, 2-204C District Construction Safety Coordinator, 2-205 Guidelines for Traffic Control Plans, 2-206G Surfacing MaterialsColor and Texture, 2-212 Keeping the Roadway Clear and Clean, 2-214C (4) Construction Engineers, Resident Engineers, and Construction Inspectors, 2-215 Construction Zone Enhanced Enforcement Program, 2-215A (1) Estimating COZEEP Funding Requirements, 2-216B Requirements of the California Manual on Uniform Traffic Control Devices, CalOES: Power Outage and Fire Recovery Resources. Then install in sequence all remaining signs and devices in the opposing direction of travel. Urgent, unpredictable situationsminor or of short durationcan arise during the work and should be addressed using engineering judgment. If a change order is processed that requires COZEEP support, and it is estimated that existing state-furnished materials funding for COZEEP is not sufficient, include additional funding for COZEEP as part of the change order. When full use is not possible, accommodate traffic by verifying a continuous roadway throughout the length of the project, achieved by using one or a combination of the following: The newly constructed highway or portions of it, A detour where traffic, including pedestrians and bicycles, is diverted over a temporary roadway, Passage of traffic through the work in progress. A spreadsheet may be used for the summary. Verify that the contractor provides a Type 1 or Type 2 for each closure as shown on Standard Plan T26 and T27, respectively. To sign up for the training, submit a training request in Staff Central for this course by following the instructions on the Division of Construction's How to Request Training intranet page.
