The DTM calculates the delay penalty during the design phase of the project. California code are designated by (CA). Imposing a 24-hour-a-day regulatory speed reduction can be difficult to justify and obtain approval for. The change order that authorizes the extra work should reflect these costs. The closure requests are stored with a SAVED status. Verify that the sign complies with the requirements of Section 12-3.32, "Portable Changeable Message Signs," of the Standard Specifications, including number of lines and characters in a line, display modes, power source, and devices to plumb and level the trailer. Every five minutes LCS reports all approved closures planned for the next 7 days, plus all current lane, ramp, and road closures due to maintenance, construction, special events, etc. Unknown time of reopening. Consult with the district traffic manager for assistance with these items. DES-PPM&OE - Bidder Inquiries Viewing - California The California MUTCD Part 6 contains figures that can be adapted for traffic-handling plans. In addition to adjustments for ordered changes, process change orders that adjust compensation when increased or decreased closures are required because of underruns or overruns in the engineers estimated quantities. Additional devices are placed in sequence, moving in the direction of the traffic flow. If advanced flaggers or additional flaggers are not shown or specified, then Caltrans pays 100 percent by change order. Request an impact study for ramp closures of short duration where the possibility of adverse results or sufficient public concern exists to identify effects on adjacent businesses. Compare the traffic control plan to site conditions. QuickMap Know before you go. Traffic queuesContain traffic queues completely within the advance warning signs of any closure. Review Section 12-3.11, Construction Area Signs, of the Standard Specifications for additional requirements. Anticipated cooling times needed for asphalt concrete pavements before opening a lane, shoulder, or ramp to public traffic. Do not allow the contractor to mix different types of temporary traffic control devices on the same alignment. 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. Acts as a resource for the resident engineer, the DTM, and the TMP manager during TMP implementation. A G20-2 "END ROAD WORK" sign, as appropriate, shall be placed at the end of the lane closure unless the end of work area is obvious or ends within a larger project's limits. Review the closure requests for compliance with the closure requirements charts and other contract requirements. Consult with your CSC, construction traffic manager, and DTM to discuss 24-hour-a-day speed reductions. If differences exist, try to make them readily apparent. Themmbm.net DA: 11 PA: 37 MOZ Rank: 60. Antelope Valley Freeway SR-14 Traffic & CHP Incidents in California For example, a project that will occur Monday through Thursday for the next week would require only one task order. District Construction should review the traffic control plan before the district submits the plans, specifications, and estimate to headquarters. 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. 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. Verify telescoping flag trees maintain an upright position when being used. Verify that no fixed objects, such as cabinets or poles, will reduce the path width at any point. Pedestrians, including persons with disabilities, need to be accommodated through and around work zones. Consider suspending work for the next shift until a written plan is provided to address future public safety. Do not allow the use of commercial pallets that exceed the maximum height. They require lane closure charts that specify when and how many lanes may be closed for construction. For their application, review the current California Manual on Uniform Traffic Control Devices (California MUTCD). Stationary closures on a traffic lane are 10-97 before placing the first cone on the traffic lane, and 10-98 after removing all the cones from the traffic lane. Take the following steps before work begins: Discuss any flagging operation with the contractor before the operation begins. Length of closureAvoid long closures with no evidence of activity. CHP policy and the COZEEP agreement require that a sergeant or higher ranked officer be assigned to oversee COZEEP officers if there are more than 4 officers assigned to a project. The selected speed should be what a driver exercising due care would drive in normal conditions of light and weather. The last level of review will be the COZEEP statewide coordinator. If a change order modifies the plans, construction engineers should take steps necessary to verify that the modified plans are adequate to provide the highest level of traffic safety and service consistent with conditions actually encountered. The purpose of the gaps is to allow drivers and passengers of vehicles to get behind the barrier in case of a disabled vehicle. Review the specification requirements and sheet T4 of the Standard Plans. Do not use a reduced regulatory speed limit as a substitute for other means of creating a safe roadway. Section 124 of the California Streets and Highways Code authorizes Caltrans to close or restrict the use of any state highway whenever it considers such actions necessary for these reasons: Closures may also be necessary after major earthquakes or other natural disasters. Restore all signs and signals to normal operation. Allow the use of paint only if the temporary traffic stripe is not required to be removed. The pending file for the project maintained by the resident engineer should include the basis of that estimate. Retroreflective bands on portable delineators. In the daily report, enter a description of the services the CHP provided, such as traffic breaks, stationary patrol upstream of the work area, or circulating patrol, and complete the CHP officer and CHP vehicle information. Providing for exit ramp traffic within the coned-off area may be difficult. Feb 26 *State Route 39 in Angeles National Forest* SR-39 is CLOSED starting at East Fork Road until further notice due to snow, ice & a rock slide in one spot. Confirm the sign is placed where it is most visible to approaching motorists. The path must be stable, firm, and slip resistant. Use tangent diagonal crossing in preference to reversing curves. 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. Obtain a contact cell phone number for the contractor before starting activities that require a portable changeable message sign and arrange for an inspection with the contractor before the first deployment. Directs the termination or modification of active planned lane closure operations when traffic delays become significant, without compromising traveler or worker safety. 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. 3. If the bid item is not included in the project, process a change order to provide a TPAR. Refer to Section 7-1.04, Public Safety, of the Standard Specifications, and Topic 902, Sight Distance and Clear Recovery Zone Standards, of the Highway Design Manual. Results will display in a new window. Verify attendance of subcontractors and other contractors personnel involved with traffic control. The contractor bears costs and expenses for additional support from the CHP, and Caltrans deducts associated costs from monies due the contractor. The resident engineer administers the COZEEP program on the project. The contract item price also includes the costs of work necessary to restore channelizers damaged by public traffic. During the preconstruction conference, discuss: https://dot.ca.gov/programs/construction/forms. In urban and suburban areas with high vehicular traffic volumes, place the signs at intersections. In accordance with Caltrans policy, no undelineated roadway can be opened to unrestricted or uncontrolled traffic. The following are typical situations in which field adjustments are necessary: If long closures are unavoidable, protect the active work area by placing barricades or drums across the closed lanes, upstream of the work area. Ideally, the assistant resident engineer should be able to communicate directly with the contractors maintenance person by radio or cell phone. For guidelines on publicizing information, refer to Section 1-206, Relations With the Media and Traveling Public, of this manual. Traffic control costs in support of extra work are to be paid as part of the extra work. The status in LCS will change to APPROVED. The LCS will notify the contractor by email of the approval or rejection. For continuous construction work zone speed limit reduction, verify that advisory warning signs are posted to alert motorist of the roadway condition as specified and as shown on the standard plans. For conditions shown on the plans that need adjustment, discuss proposed changes with the district Traffic Operations Office. Verify that the color of the portable transverse rumble strips is black or orange and arranged in accordance with Standard Plan T13. 2 Comments. When work activities are complete for the day, verify that the contractor removes or covers the signs. If this equality is not possible, confirm that the design speed differential is no more than 10 mph. Verify the contractor installs Type P or Type R markers when required. Closures are reported and managed using the web-based Lane Closure System (LCS) Mobile application. Verify temporary pavement delineation is maintained until it is replaced with the permanent pavement delineation. You may also consult the district Traffic Operations office. San Bernardino County Transportation Authority (SBCTA) Please visit SR 210 Base Line Project's website for the latest news regarding the 210 freeway construction. The following is a list of CalTrans lane closures, road construction, and blocked lanes that are active or plannded for on Highway SR-17 Updated Mar 02, 2023, 9:33 AM CalTrans Lane & Road Closures SR-17 Request the user interface software and provide it to the Transportation Management Center for installation. Perform additional reviews periodically throughout the construction project, since changes may affect the facilitys effectiveness. Caltrans - Division of Construction - California Review sheet T3B of the Standard Plans for staking requirements. The between the L tapers required for each closed traffic lane; Lane Closure Report for the week of 7/29/19 - 8/2/19 Inyo, Mono & Eastern Kern Counties - The California Department of Transportation (Caltrans) would like Alert Caltrans Traffic Map Chain Control Map Route Conditions State Route Closures CHP Incidents TMC ALERT Interstate 10 (I-10) is closed between Route 86 and Route 177 due to storm damage. Under the agreement, Caltrans pays the CHP for furnishing officers and cars for construction zones. 2.0 Work Zone Impacts Assessment Process Example Verify the contractor follows the notification and signing requirements before setting up any traffic control systems. Evaluate the COZEEP use criteria for complete highway closures and nighttime closures of one or more lanes on multilane highways. Record inspection dates and conditions observed in the project records. Document the reasons for COZEEP use. The Transportation Management Plan Guidelines describe the roles and responsibilities of the construction traffic manager who works in cooperation with the CSC. The following COZEEP use criteria do not form an all-inclusive list. Verify the contractor uses an impact attenuator vehicle as a shadow vehicle in moving closures and during placement and removal of components in stationary closures. The statewide agreement requires that cancellations be made during normal working hours and at least 24 hours before the time that the CHP is to arrive on the project. Each flag shall be at least 16" x 16" To establish the geometry, markings, devices, and signs that existed during the project, maintain in sufficient detail a record of the placement into service, the changes, and the discontinuance of roadways and detours. Review Sections 12-4.04, Temporary Pedestrian Access Routes, and 16-2.02, Temporary Pedestrian Facilities, of the Standard Specifications for the temporary pedestrian facilities requirements. Contract managers direct their respective separate contracts or agreements, such as for rideshare activities, transit activities, and public awareness campaigns. Verify that pedestrian facilities comply with the Americans with Disabilities Act. Check that portable transverse rumble strips are not placed on sharp horizontal or vertical curves or through pedestrian routes. 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. Verify Type K temporary railing is placed on a firm, stable foundation uniformly graded throughout the entire length of the railing. As early as possible, verify that all Department-furnished equipment is available at the location specified. The public distribution of the environmental document includes local businesses that may be affected and notifies them of any public hearing. Remind the contractor to notify the regional notification centers before digging for the installation of signposts. Night construction activities, such as replacing pavement slab, replacing bridge joint seals, and replacing pavement markers, that can create an unexpected condition for driverseven those familiar with the highway. Please use an alternate route. Changes to any of these plans may alter the need for temporary crash cushion modules. A square joint is even more necessary when asphalt concrete joins concrete, because at night and during rainy weather, the joints often stand out more prominently than traffic lane lines. Verify that the impact attenuator vehicle complies with all specification requirements. Confirm the contractor uses the long-term temporary pavement marker for 180 days or less and the short-term temporary pavement marker for 14 days or less. Consider driver expectation and ambient light in the area of the crossover for temporary lighting. A general time-scaled logic diagram displaying the major activities and sequence of planned activities that comply with special provision requirements. The maintaining traffic special provisions for capital projects provide for compensating contractors for early pickup. Caltrans reimburses CHP officers who provide COZEEP services on overtime at time and a half. Based on traffic counts, the district traffic operations office determines times for closures and for night work. Confirm that changeable message signs, highway advisory radio, and other media tools provide accurate and timely information to motorists regarding closure times. Lane Closure System (LCS) Mobile Statusing - California Flashing beacons shall be placed at the locations indicated for in size and shall be orange or fluorescent red-orange in color. Safety reviews conducted during the projects development may identify other deciding factors. Verify that Category 3 temporary traffic control devices are on the Authorized Material List for Highway Safety Features. Process, justify, and document the request the same way as any other fund request. Confirm that advance warning signs for the new taper are located correctly. Lane Closure System - California Verify the contractor conducts a meeting with all involved parties to discuss the operation of the impact attenuator vehicle. For this reason, district coordinators should not return an invoice to the CHP because the billing rates shown on the invoice do not agree with the rates in the contract. Road Information - California Impact attenuator vehicles are paid for as part of the contract item for the traffic control system. An impact attenuator vehicle must be used for the placement and removal of temporary traffic control devices when required by the contract. 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 local CHP contact person will note in the cancellation form if Caltrans is being charged a cancellation or 4-hour overtime fee. Caltrans should order early pickup only when traveler and worker safety will not be compromised. 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. For all project work, the lump sum payment for the traffic control system includes payment for all labor, equipment, and materials to install, maintain, and remove the traffic control system as shown on the plans or Standard Plans. Do not sever or move a pedestrian route for nonconstruction activities such as parking for vehicles and equipment. Confirm compliance with the minimum legibility distances. Verify the crash cushion array is in place before opening traffic lanes adjacent to the protected obstacle. Move the workers and equipment onto the closed lanes only after all system components are in place. Do not allow the use of sandbags. Significant traffic effectan individual traffic delay of 30 minutes or more above normal travel time during recurring congestion on the existing facility. The following procedures are intended to assist resident engineers in obtaining and tracking COZEEP services and to help Caltrans reconcile the CHP billing system and facilitate payment to the CHP. CHP Careers. Obtain the information of trained contractor representatives, including whether they will be requesting or providing a status of closures, or both. Allow only the use of sandbags when it is necessary to weigh down sign standards to prevent the wind from overturning them. It is an enhancement tool for construction zones and is not intended as a replacement for other temporary traffic control measures. Confirm the contractor maintains barricades in good condition and keeps the reflective surfaces clean. Verify portable radar speed feedback sign systems comply with the requirements in Section 12-3.37 Portable Radar Speed Feedback Sign Systems of the Standard Specifications. Chapter 2: Safety and Traffic, Section 2: Traffic. Design for the speed that vehicles will travel. 2. Form CEM-2303, Temporary Pedestrian Access Route Sidewalk Detour Inspection Report, may be used by the engineer and the contractor to report weekly inspections if the temporary pedestrian access route is provided using an existing pedestrian route. Visualize what effects changing conditions of visibility and lighting will create. The resident engineer must track COZEEP hours used and estimate expenditures each month. Include the district TMP manager, the DTM, and the public information officer as appropriate in preconstruction or work planning meetings. 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. Initial placement of each barricade is paid for as a contract item at the time of placement. 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. Damaged barricades should be repaired at the contractors expense, regardless of the cause, including damage by public traffic. Unstable snow conditions have prompted closure of Highway 32 between Humboldt Rd in the Lomo area of Butte County and the Highway 36 junction in Tehama. When severe congestion is forecast because of capacity reductions, include plans for using the media to notify the public, Construction Zone Enhanced Enforcement Program (COZEEP) services, alternate route development, metering by upstream ramp closures, changeable message signs, radar feedback speed signs, highway advisory radios, and monitoring the end of the traffic queue. Be aggressive in seeking changes to improve the situation. Verify that all the necessary signs, cones, drums, and other equipment are on hand before the system is set up for the first time. Document this inspection in the daily report; indicate weather, traffic conditions, and time of inspection. Inspect TPARs weekly to verify that they are clean and unobstructed and comply with the Americans with Disabilities Act and the work plan required by the specifications. Reviewing the needs and control of all road users is an essential part of highway construction, utility work, maintenance operations, and the management of traffic incidents through a work zone. 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. It is not necessary to restudy impact previously studied during planning and design unless significant commercial development has occurred in the area in the interim. Include compensation or credit in the change order when an ordered change in the work affects the contract item for the traffic control system.
