Department Deputy Directive 60 (DD-60) requires Transportation Management Plans (TMP) and contingency plans for all construction, maintenance, encroachment permit, planned emergency restoration, locally or specially funded, or other activities on the State Highway System. Where several consecutive or linking projects or activities within a region or corridor create a cumulative need for a TMP, the Department coordinates individual TMPs or develops a single interregional TMP.
A Transportation Management Plan (TMP) is a method for minimizing construction activity-related traffic delay and accidents by the effective application of traditional traffic handling practices and an innovative combination of public and motorist information, traffic demand management, incident management, system management, construction strategies, alternate routes and other strategies. TMP. Guidelines are provided by the Division of Traffic Operations, Office of Systems Management Operations and may be accessed on their Intranet website.
All TMPs share the common goal of congestion relief during construction by managing traffic flow and balancing traffic demand with highway capacity through the project area, or by using the entire corridor. A blanket TMP. is a generic list of actions that would be taken to keep delay below the delay threshold when performing activities on highways and are usually for maintenance and encroachment permit activities. Each district Maintenance and Encroachment Permit office should have a list of activities to which blanket TMPs apply.
Generally, a high-impact project requires a major TMP to be developed by a Traffic Management Team comprised of Caltrans representatives from Public Information, Project Development, Construction, Traffic Operations, Public Transportation, Maintenance, Structures, California Highway Patrol, FHWA, and other involved agencies (employers, merchants, developers, transit operators, ridesharing agencies, neighborhood and special interest groups, emergency services, and Transportation Management Associations). Appropriate members of the PDT should also be members of the TMP team.
Compared to standard traffic control systems and blanket TMP’s, a major TMP is typically in place over a longer period of time and is customized to meet the unique needs of the impacted corridor, sometimes implemented up to a year or more prior to the start of actual construction, with specific elements often implemented to coincide with construction phasing.
Prior to PID approval, the project engineer sends conceptual geometrics to the District Traffic Manager or District TMP Coordinator for evaluation. The District Traffic Manager or TMP Coordinator estimates the extent of the TMP required and determines whether potential traffic delays are anticipated that cannot be mitigated by traditional traffic handling practices or well-planned construction staging. The District Traffic Manager or TMP Coordinator must sign-off on the TMP DATA SHEET to be included in the PID. A TMP cost estimate should be developed for each alternative being considered. The cost of a TMP could range from a small percentage of the overall project cost, to 20 percent or more.
Some Districts have a pre-established TMP team and TMP preparation process, and requests for a TMP are sent to and prepared by the established team. For Districts that do not have an established TMP process and team, the project engineer must consult with the District Traffic Manager to form a TMP team. The TMP team prepares the TMP but the project engineer with the support of the TMP team is responsible for the cost estimate.
