The following appendix illustrates the process used by the Maricopa Association of Governments (MAG).(57) The process starts with the development of goals (see table 32 ) and progresses to the development of initiatives to achieve these goals and the functions required (see table 33 ). Figure 70 shows the measures used to evaluate the goals.
Table 32. Development of goals.
Operational Categories | 3-Year Goal | 5-Year Goal |
---|---|---|
Freeway mobility | Limit the percent increase in average travel time to less than the percent increase in traffic volume. | Same as 3-year goal |
Arterial mobility |
|
|
Freeway incident management | Reduce
incident duration by 10 percent. |
Reduce
incident duration by 20 percent. |
Freeway arterial interface | Establish integrated freeway-arterial corridor operations on one corridor. | Establish
integrated freeway-arterial corridor operations on three corridors. |
Arterial incident management | Conduct a feasibility and planning study for a multi-jurisdictional arterial incident management program. | Implement a multi-jurisdictional arterial incident management program (based on outcomes of feasibility study). |
Arterial operations | Establish a regional standard for implementation of emergency vehicle signal preemption (EVSP). | Ensure adoption of the EVSP standard by each of the MAG member agencies and implement the standard on 100 percent of the traffic signals with EVSP. |
Transit mobility | Deploy a transit signal priority pilot project. | Deploy transit signal priority to bus rapid transit routes where beneficial. |
Computer system reliability |
|
No goal. |
Multi-agency coordination |
|
|
Travel information provision |
|

Table 33. Development of initiatives.
Operational Categories | Initiatives | Functions |
---|---|---|
Regional Traffic Signal Optimization Program | Improved traffic signal timing within cities and across jurisdiction boundaries will result from better regional traffic engineering collaboration. |
|
Arterial and freeway incident | Improved incident management can be achieved with better collaboration of the fire and public safety personnel with the transportation departments. | Freeways:
|
Shared maintenance resources | Improved system performance and significant cost savings to the region will result from sharing resources (staff and equipment). |
|
Freeway-arterial operations | An emphasis and focus on improving the operations of the arterials and freeways at traffic interchanges can be beneficial in optimizing the operation of the freeways and arterials. | Plan, deploy, operate, and maintain a freeway-arterial corridor operations pilot project. |
Emergency vehicle signal preemption | Preemption on a regional basis will be more effective and safer with a common set of standards for its implementation. | Develop regionally accepted standard for emergency vehicle signal preemption. |
Transit signal priority | The implementation of transit signal priority on a corridor will demonstrate the effectiveness of this concept for regional transit mobility. | Plan, deploy, operate, maintain, and evaluate a transit signal priority pilot project. |
Center-to-center communications | Better communications between agencies. | Establish center-to-center communications between agencies. |
Archived data | Collecting and storing data from implemented transportation systems will be an excellent resource for the region in planning operational enhancements. | Develop and implement a regional data archiving system. |
Local TMC and ADOT TMC operators | The effectiveness of TMC operators will be improved with better coordination and communication between themselves. |
|
Travel information | Improved travel information in the MAG region will benefit the regional mobility. |
|
Performance Measurement | The effectiveness of all the initiatives can be measured through a performance measurement program. | Develop performance measurement program. |
