Consult with the district traffic engineer for other acceptable means to protect the sign instead of the Type K temporary railing required by the specifications. Do not allow the contractor to use the double-stick butyl pads provided by the channelizer manufacturer; these pads do not meet Caltrans requirements. Temporary traffic control devices are divided into categories: The condition of temporary traffic control devices should comply with the most current edition of the American Traffic Safety Services Association (ATSSA) publication Quality Guidelines for Temporary Traffic Control Devices and Features. For conditions shown on the plans that need adjustment, discuss proposed changes with the district Traffic Operations Office.

Each advance warning sign shall be equipped Review sheet T3B of the Standard Plans for staking requirements. Portable delineators are paid for as part of the contract item for the traffic control system. When an AFAD becomes inoperable, notify the contractor to immediately replace it with an identical device, use a flagger with the appropriate-size advance warning sign and gate cones as shown in Standard Plan T13 or stop all construction activities that require the device to be in operation. 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. Also, when possible, use barrier vehicles or an impact attenuator vehicle between the approaching motorist and workers on foot. The project engineer should include adequate COZEEP funds in the project estimate. End-of-queue management is desirable at locations where traffic queues are anticipated. The cost estimate used in the plans, specifications, and estimate is based on the expected number of events needing COZEEP identified during project development. The COZEEP coordinator must verify invoices received from CHP against the tracking expenditures spreadsheet. Camino, CA 95709 When the work has safely progressed beyond the supplemental taper, remove the upstream taper and tangent.

Anticipated cooling times needed for asphalt concrete pavements before opening a lane, shoulder, or ramp to public traffic. Verify no-passing zone signs are removed when no longer required. 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. Consult your district COZEEP coordinator for a current estimate of hourly and mileage COZEEP cost. Basic instructions usually apply more to the planning and design phase of a project, but they also help provide construction personnel with basic concepts for safe and efficient traffic flow through a highway construction project. Similarly, certain striping operations require the operator to operate against live traffic because of clearances. Make sure that the contractor places the portable radar speed feedback sign systems as shown on Standard Plans T18, T19, T20, and T21 and as far from the traveled way as practical, where it is visible and legible to approaching traffic, taking into account any vertical or horizontal roadway curvatures. Clearly identify early-finish and late-finish milestones for every major activity. Major lane closuresthose expected to result in significant traffic effects despite the implementation of TMPs. Make sure your designated staff and other state staff involved with traffic control attend the meeting when possible. Once the district COZEEP coordinator receives the COZEEP daily reports, they should be logged into the COZEEP service summary to track COZEEP use. Verify that Category 3 temporary traffic control devices are on the Authorized Material List for Highway Safety Features. In Part 4, identify a Caltrans project supervisor, usually the resident engineer or an assistant resident engineer. Construction situations frequently require a lateral shifting of traffic in relation to the normal path of travel and may involve dropping a lane. The California Highway Patrol. During the planning and design phase of any project, an impact study is made for a proposed prolonged ramp closure. Do not allow the use of commercial pallets that exceed the maximum height.

The project has sufficient funds available to pay for the CHP support. Where possible, compensate for a required reduction of one by an improvement of another. Be aware that reductions in the width or number of lanes affect the capacity and flow of traffic. Verify that additional speed limit signs indicating the reduced speed limit are placed within the construction work zone as specified. Inform the Transportation Permits Unit 15 days in advance of the closure. The contractor bears costs and expenses for additional support from the CHP, and Caltrans deducts associated costs from monies due the contractor. Examples of unacceptable messages include Drive carefully, Have a Nice Day, and Thank you.. Initial placement of each barricade is paid for as a contract item at the time of placement. For example, compensate for a sharper curve with solutions such as increased lane width or a clear recovery zone. In that case, portable flashing beacons are paid for as part of the contract item for the traffic control system. For public convenience, such as routing traffic through detours when not shown on the plans and when ordered by the engineer, providing flaggers is change order work for which Caltrans pays 100 percent. Verify that the impact attenuator vehicle complies with all specification requirements. When necessary, ask the contractor to adjust placement or message content of signs based on changing project or traffic conditions. Drivers should be able to read the entire message at least two times before passing the sign. 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. Evaluate the COZEEP use criteria for complete highway closures and nighttime closures of one or more lanes on multilane highways. Pallets that exceed this height raise the sand in the crash cushions above an acceptable level.

The California Department of Transportation (Caltrans) and the California Office of Traffic Safety (OTS) today unveiled Safety Sam as their new safety cone mascot. The contract item price includes the costs of maintaining, replacing, and repairing channelizers. 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. Click on the Nextbutton at the bottom right to go to the next slide. Construction staff needs to complete the job-related temporary pedestrian facilities training within 6 months of assignment to inspect or administer contracts if they have not taken the online training within the previous 3 years. Caltrans Highway Information Network (CHIN) Incidents CHIN incidents that involve closed lanes are indicated by orange triangular markers. 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. The resident engineer must track COZEEP hours used and estimate expenditures each month. These Standard Specifications sections apply to pedestrian facilities: Verify that the contractor adheres to the following: At the preconstruction conference, discuss the need for temporary pedestrian facilities and ADA requirements. Advisory speeds are not enforceable by the CHP. How the contractor will meet the projected rates for material delivery to the job site. 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. Use an appropriate material, such as asphalt concrete, for the surface of all roadways and detours, except very temporary or minor facilities. During daylight operations, the vehicles facing oncoming traffic should have their headlights and their flashing amber lights turned on at all times. For details related to preconstruction conferences, refer to Section 5-003, Preconstruction Conferences with the Contractor, of this manual. Refer to Section 4-1202C (1a), Lane Closure System, of this manual. If you exit without completing the training, you will have to start over. 2.
