A Traffic Control Plan (TCP) in Alhambra, also called a work zone traffic control plan, temporary traffic control plan, construction work zone traffic control plan, work zone traffic control plan, or temporary traffic control plan, consists of well-planned written instructions, and often accurately-designed engineered drawings, that a contractor uses to construct a project on a roadway while guiding and protecting traffic passing through or around a construction work zone.
The primary function of a temporary traffic control plan is to provide safe and efficient movement of the traveling public in Alhambra through or around work zones while protecting on-site workers, incident responders, and equipment. A temporary traffic control plan in Alhambra must provide for the efficient construction and maintenance of the highway. The needs, control, and safety of vehicular traffic, bicyclists, and pedestrians through a work zone are essential to a well-designed work zone traffic control plan.
Therefore, the four primary functions of a work zone traffic control plan are to provide:
- Enhanced Safety
- Minimized Inconvenience
- Efficient Traffic Flow
- Adequate Mobility for All Road Users
Planning a work zone traffic control plan in Alhambra should start as early as possible, preferably in the project planning and development phase, especially for larger, significant, and more complex projects. A well-designed temporary traffic control plan in Alhambra must consider a variety of staging options for the construction work zone traffic control plan including options where the separation between workers and the traveling public can be maximized.
At AHTC, our traffic engineers regularly communicate with the project team members and use all available resources when optimizing the temporary traffic control plan particularly resident engineer’s staff and the contractor to address constructability issues.
What Do Traffic Control Plans Include?
A temporary traffic control plan in Alhambra should include project-specific instructions sheet(s). The plan sheets are used as a graphical representation of the construction area’s work zone traffic control plan. The instruction sheets provide the contractor with additional information and instructions showing how to set up or stage the construction work zone area in Alhambra for a project while still providing safe and efficient passage for live traffic.
For smaller projects in Alhambra that do not need staging, the project may be constructed without the need for involved stages and detours. Therefore, they may not need a temporary traffic control plan.
What factors are used in developing a temporary traffic control plan in Alhambra?
The following are specific factors that can influence the design of a temporary traffic control plan:
- Traffic data obtained in Alhambra – Existing traffic volumes, street capacity, 85th percentile speeds, truck traffic volume, crash history, and problem areas within the project limits.
- The highway characteristics – Horizontal and vertical alignments, number of traffic lanes, lane and shoulder widths, pavement types and conditions, sight distances, surrounding terrain, and local environs (e.g., urban, rural, commercial, residential, etc.).
- Traffic control devices – Signs, striping, structures, traffic signals, roadside barriers, pavement markings, lighting, and other traffic control devices.
- Construction details and timing – Materials used for the finished product, excavation quantities and locations, project durations, available right of way and work area separation from traffic, and the number of accesses adjacent to work areas.
A construction work zone traffic control plan in Alhambra is designed and typically arranged as follows:
- Cover Sheet(s) – Include instructions and information for construction activities, customized temporary signs, and other unique devices and products.
- Plan and Detour Sheets – Display construction staging drawings identifying the portions of the work area in Alhambra used by live traffic and those available to the contractor for construction. Includes details for the location, type, and quantity of traffic control devices required to guide and protect traffic through the work zone. Display designated route(s) for traffic to circumvent the work zone using existing alternate routes in Alhambra. Includes details for points of closure, detour-specific signing, devices, and other detour route conditions, restrictions, and information.
