2.0 Identifying Candidate TMCs for Weather Information Integration

This section describes the process to select TMCs for participation, the TMCs selected, and the specific plans developed for each TMC to conduct the self-evaluation. The selection and planning processes were carried out to:

  1. Identify criteria by which TMC’s would be evaluated and selected for project participation
  2. Identify candidate TMC’s and recommend a limited number to participate
  3. Define a project deployment plan for following up with each TMC selected

The deployment plan was completed in April 2009 as an internal project document. It contained a list of all TMCs contacted and their levels of interest in weather information integration.

Five TMC candidates were selected because it was felt they would significantly benefit from enhancing weather information integration in their operations and were interested and motivated to participate. These candidate TMCs were grouped into two tiers and received different levels of assistance from the consultant team to work through the Guide and develop a weather integration plan.

The five selected TMCs are a good representation of TMCs across the country with varied geographic locations, types of operations, and weather conditions that impact their respective transportation systems. Also, the TMCs varied in their current levels of weather integration and therefore offered good opportunities to identify and evaluate different integration strategies.

2.1 TMC Site Selection Process

The goal of the selection process was to identify TMCs that the consultant team could support to 1) conduct a self-evaluation that is responsive to their needs and results in weather integration strategies suitable for deployment, and 2) prepare a weather integration plan.

2.1.1 Selection Criteria

Selecting the most appropriate TMCs was essential to the success of the project. The consultant team established and used the following criteria to screen a long list of potential TMCs and select those that would receive assistance to work through the Guide and develop an integration plan.

  1. Region – a balanced representation of TMCs across the country
  2. Operations – variety of operational types with at least one focused on arterial management
  3. Weather impacting transportation system – variety of weather types
  4. Level of weather impacts on transportation system – significant weather impacts
  5. Current level of availability and use of weather information in operations – range from low to high to reflect the circumstances of TMCs across the country
  6. Interest in integrating weather information into TMC operations – strong interest in enhancing their level of weather integration
  7. Potential to be national case study example of weather information integration – high potential to serve as a national example
  8. Extent of institutional and/or technological barriers – indication of low barriers to weather integration
  9. Willingness to participate in the project – Strong willingness to participate

It was important that a TMC indicated a strong interest in participating in the process; however, the focus was on identifying TMCs that could demonstrate the benefits of integration and were diverse in the types of weather integration they sought and the weather and operational characteristics of their TMC location in order to enhance the potential marketing insights and benefits. Additionally, diverse types of transportation operations were also important, with the goal of including at least one TMC that managed an arterial network. Table 1 summarizes the selection criteria and defines the anticipated variation in each of the criteria and desired outcome for each of the TMCs. Recognizing that it would be difficult to find TMCs that are ideal with respect to every criterion, the selection process sought to identify TMCs that most closely met the project goals.

2.1.2 Identifying Candidate TMCs

The process to identify candidate TMCs began with the development of a list of potential candidates, considering the selection criteria described above and the following components:

This resulted in a list of thirty-nine potential TMCs. Of the original thirty-nine, the consultant team discussed the potential project participation with personnel from twenty-three TMCs. Once enough TMCs were identified, the consultant team stopped contacting TMCs.

The consultant team contacted the TMCs by phone to learn more about their operations and interest level, asking a set of questions based on each of the selection criteria to determine their suitability for participation. The results of these discussions and recommendations of TMCs to work through the self-evaluation and integration planning processes are presented in the next section.

2.1.3 Selection of the Most Promising TMCs

Based on the responses during the phone interviews, the TMCs were categorized as follows:

These five TMCs, along with their strong interest, exhibited the right conditions to benefit from enhanced weather integration. Additional phone conversations were conducted with these TMCs to learn more about the possibilities of their involvement and to ensure their full commitment to the self-evaluation process and development of an integration plan centered around their selected weather integration strategies (from the Guide).

This project was scoped to originally identify and work with three TMCs (Tier 1). In order to be responsive to the interests of the remaining qualified TMCs, the consultant team, in consultation with FHWA, recommended adding a second group (Tier 2) of TMCs to the project. These two tiers are defined as follows:

The Tier 2 concept was new to the project, and offered an opportunity to determine whether TMCs can be expected to seek out the Guide on-line and successfully carry out a self-evaluation and planning process essentially on their own and without assistance. These Tier 2 TMCs would also serve as alternates to the Tier 1 group should an event arise that would prevent one of them from completing the project, and the opportunity to expose more TMCs to the Guide and obtain further input regarding its usefulness.

Table 2 identifies the five TMCs selected for project participation and their responses to each of the selection criteria.

2.2 Deployment Plans for Selected TMCs

The three recommended Tier 1 TMCs received extensive support from the consultant team as they implemented the self-evaluation and integration planning process. The two Tier 2 sites went through the same process mostly on their own, with a reduced level of interaction with the consultant team. During this process, the consultant team’s objectives were as follows:

2.2.1 Tier 1 TMCs

The consultant team worked closely with each of the Tier 1 TMCs to work through the self-evaluation Guide, identify weather integration strategies, and develop an Integration Plan. As part of this assistance, the consultant conducted up to four site visits to provide structured support to the TMCs, as follows:

In addition to these site visits, the consultant conducted monthly (or as needed) phone discussions with the TMC lead contact to review progress, answer questions, and provide assistance to ensure the TMC maintained focus on the tasks and adhered to the agreed upon schedule.

Specific deployment plans were prepared and focused on each TMC that defined the activities to be conducted as part of the project tasks. Table 3, Table 4 and Table 5 provide the deployment plans. Some schedule alterations were made to ensure a smooth project implementation.
