WORK ZONE TRAFFIC CONTROL 1101 -1 TRANSPORTATION MANAGEMENT PLAN (TMP) Maintain traffic through work zones in accordance with the se Specifications , the MUTCD, Roadway Standard Drawings , 23 CFR 630 Subparts J and K and the Transportation Management Plan (TMP) . Below is a list of the possible TMP components:
A.Temporary Traffic Control Plan (TTC),
B.Transportation Operations Plan (TO), and
C.Public Information Plan (PI). A TMP will always have a TTC component. The TTC will contain the project notes, phasing, detail sheets and other supporting information. 1101 -2 TEMPORARY TRAFFIC CONTROL PLAN (TTC)
A.General Typically, phasing and drawings govern over project notes, and local notes govern over general notes. If a conflict arises in the TTC , refer to Article 105 -4.
B.Phasing Complete the requirements of each phase before proceeding to the next phase and the requirements of each step before proceeding to the next step unless the plans permit work to be performed concurrently. If a TTC phasing is broken into areas, work may be performed in more than one area simultaneously as described in the plan.
C.Project Notes Two types of project notes may be included in the TTC:
1.General Notes apply at all times during the project, and
2.Local Notes ap ply only for the specific times and locations that they are referred to in the phasing and detail sheets.
D.Alternate to Transportation Management Plan If desired, submit an alternate TMP a minimum of 30 calendar days in advance of the anticipated implementation to allow for adequate review time. Do not implement alternate plans for traffic control until approved in writing and properly sealed. No adjustment in compensation or extension of the completion date(s) will be allowed due to the review time of the alternate. If an alternate T MP is implemented, the Contractor shall be responsible for any unanticipated changes to subsequent phases and steps.
11-2 (E) Temporary Traffic Control Plan Not Ful ly Covered in the Contract
When the TTC does not cover a particular work function, notify the Engineer to allow for the development or modification of a sealed set of the Temporary Traffic Control Plans. 1101 -3 BLASTING ZONE When blasting operations are within 1, 000 f eet of a travelway , provide the appropriate traffic control as shown in the plans and/or the Roadway Standard Drawings . 1101 -4 CONSTRUCTION VEHICLE CROSSINGS Do not cross the median, ramps or loops with vehicles or equipment unless a specific location for crossing is approved and required traffic control devices are used as shown in the Roadway Standard Drawings . 1101 -5 ON-ROAD CONSTRUCTI ON VEHICLES When operating outside of a closed lane or haul road crossing in a work zone, on- road construction vehicles are subject to the Department’s Division of Motor Vehicle weight and safety regulations as commercial vehicles . Work vehicles must alwa ys use warning lights with at least 50% being amber in color attached to the vehicle as high as possible and in a manner such that they are not obscured by equipment or supplies. Vehicle hazard signals or lights may be used to supplement this requirement. This requirement applies to all work vehicles and equipment not inside lane closures or behind barriers. This requirement does not apply to dump trucks but it is encouraged. 1101 -6 EXCAVATIONS WITHIN TRAVELWAY During the process of excavating in a travelway where traffic is to be later maintained, make provisions to backfill and repair any excavated or damaged pavement before allowing traffic to proceed over the affected lanes. In low speed areas (35 mph or less) , metal plates may be used to cover excavated areas. 1101 -7 HAULING OPERATIONS Comply with the multiple and single vehicle hauling restrictions as shown in the TMP when performing hauling of equipment or materials to or from the project. Define “Multiple Vehicle Hauling ” as the hauling of equipment or materials to or from the project with delivery at intervals of less than 5 minutes o r results in more than one vehicle at a particular work site at a time. Define “Single Vehicle Hauling ” as the hauling of equipment or materials to or from the project with delivery at intervals of more than 5 minutes and results in no more than one vehicl e at a particular work site at a time. Do not conduct any hauling operations against the flow of traffic of an open travelway unless an approved temporary barrier or guardrail separates the traffic from the hauling operation. On multi- lane, controlled access roadways, haul vehicles shall not enter/exit an open travel lane at speeds more than 10 mph below the posted speed limit. Haul vehicle acceleration to within 10 mph of the posted speed limit shall only occur on paved surfaces. 1101 -8 MATERIAL AND EQUIPMENT STORAGE When work is not in progress, keep all personnel, equipment, machinery, tools, construction debris , materials and supplies away from active travel lanes that meets Table 1101 -1.
11-3 Table 1101 -1
MATERIAL AND EQUIPMENT STORAGE FROM ACTIVE TRAVEL LANES Posted Speed Limit (mph) Distance (ft) 40 or less ≥ 18
45-50 ≥ 28
55 ≥ 32 60 or higher ≥ 40 When vehicles, equipment and materials are protected by concrete barrier or guardrail, they shall be offset at least 5 f eet from the barrier or guardrail. 1101 -9 PARKING OF PERSONAL VEHICLES Provide staging areas for personal vehicle parking in accordance with Article 1101- 8 or as directed by the Engineer before use. 1101 -10 PROTECTION OF HAZARDS Mark all hazards with signs, barricades, drums or other warning devices. At each location where work is started which creates a safety hazard, continue the work until completed to the extent that the safety hazard i s eliminated. If the work is not pursued in a continuous manner the Engineer will not allow any other work on the project to be performed until the existing safety hazard is eliminated. 1101 -11 TEMPORARY LANE CLOSURES
A.General Operate all equipment and personnel within the designated work area during lane closures. Do not impede or stop traffic for the purpose of performing construction related work on the traffic side of the lane closure, except when called for in the TMP . Install lane closures with the traffic flow, beginning with devices on the upstream side of traffic. Remove lane closures against the traffic flow, beginning with devices on the downstream side of traffic. Vehicles used to install or remove lane closures shall have vehicle warning lights as described in Article 1101 -5.
B.Intersections When construction proceeds through an intersection, provide flaggers and all other necessary traffic control as required by the TMP to direct the traffic through the intersection. When an intersection is signalized, place the signal in flash mode and provide law enforcement or other adequate traffic control measure to direct traffic through the intersection before beginning work in the intersection. 1101 -12 TEMPORARY ROAD CLOSURES
A.Traffic Pattern Alterations Notify the Engineer 30 calendar days before altering the existing traffic pattern , unless otherwise stated in the TMP . Plan all traffic pattern alterations and m eet with the Engineer to discuss the implementation strategy before altering traffic. The Engineer will notify the proper authorities and other affected parties as necessary.
B.Detour Ensure that all required detour signing and delineation, including work done by others, are in place before placing traffic onto a detour.
11-4 (C) Traffic Stoppage
