Traffic Signal Program Model
State of the Practice
Relating the Capability Maturity Assessment to Traffic Signal Programs
This Five Minute Assessment tool is designed to help organizations assess their organizational capability and maturity as a valuation of the risks presented to the attainment of the programs goals and objectives. This assessment is modeled after the AASHTO Transportation Systems Operations and Management Guidance which is founded on the Capability Maturity Model using the following six dimensions of capability:
- Business Processes,
- Systems and Technology,
- Organization and Workforce,
- Performance Measurement, and
However, this assessment has been modified to specifically address traffic signal programs. To apply the outcome of the assessment it is helpful to relate each of the preceding dimensions of the capability maturity to program areas that are typical of organizations responsible for the management and operation of signalized intersections. The figure below provides a simplified model of a traffic signal program, it includes four program areas, Systems and Technology, Business Processes, Workforce, Management and Administration and demonstrates the interrelatedness of each program area. The performance measurement area is a resource to measure how effectively each area of the program is supporting the attainment of the goals and objectives of the program. By combining the CMM assessment technique with the traffic signal program model the presence of gaps in capability become an indicator of risk within any of the four program areas to the attainment of program goals and objectives.
Systems and Technology
The infrastructure and systems that apply strategies and tactics to attain operations and maintenance objectives. The system owner interacts and affects system users through the systems and technology area. The program area includes:
|Mast Arms||Traffic Signal Controllers||Traffic Responsive|
|Signal Displays||Central Control Systems||ATSMPs|
Workforce characterizes the people within the organization. They carry beliefs, attitudes and behaviors that are influenced by their education and training to produce knowledge. The workforce possess the skills and experience that are required to carry out tasks, interact with systems and technology and provide the information that is critical to the management and administration program area to prepare for and address resource needs. The elements of the workforce area includes:
|Positions||Knowledge, Skills and Abilities|
Business processes are the activities performed by the program to plan, design, construct, operate and maintain the systems and technology area. The business process area also contains processes and activities to support management and administration activities such as procurement, performance reporting and so forth.
Tasks: Connect Strategies and Tactics in task areas to Goals and Objectives. Assessment of capability via CMM.
Management and Administration
The management and administration program area is responsible for setting the overall direction of the program, ensuring that adequate resources levels are sustained to support program functions, to interact internally and externally to report outcomes, to collaborate to achieve program goals, to establish and/or evolve organizational culture, and ensure the satisfaction of the programs customers and stakeholders. Routine assessments of the programs capability and maturity is a function of the management and administration area of the program.
