Task 1: Conduct Literature Review, Engage Leadership, and Determine SOM Staffing Estimates Task 1 involved four major subcomponents. First, the research team built on the preliminary literature review by further investigating the results of NCHRP Project 20-77 and other current materials to more clearly understand the workforce trends impacting SOM occupations. Second, we engaged transportation leadership across the United States to describe current and anticipated future SOM employment needs and the technical knowledge requirements for SOM careers. Third, we reviewed U.S. Department of Labor (DOL) and Department of Transportation (DOT) information to determine if SOM staff positions are adequately addressed in employment statistics. This involved developing estimates of national and regional (e.g., by state) needs for SOM staff, for the years 2005, 2010, 2015, and 2020. Finally, we determined whether staffing needs represent new employment or reclassification of existing positions. Each of these four subtasks is described in this section. Subtask 1.1--Conducting the Literature Review. To fully understand SOM occupations, our team conducted a literature review to identify and assemble information from United States and international published research, technical reports, conference presentations, and case studies on SOM employment trends. An overview of the documents we reviewed is provided in Exhibit 1.

Exhibit 1 (Continued) Literature Review Sources Journals devoted to applied problems in Position description and skills databases, such as the organizations, such as Personnel Psychology, Academy Occupational Information Network (O*NET) and the of Management Journal, Public Personnel Management, National Transportation Training Resource. Journal of Applied Psychology, and Journal of Organizational Behavior. Industry journals, such as Transportation and Transportation Quarterly. The primary outcome of the Task 1 literature review was to establish a preliminary definition of past, current, and future SOM employment trends. This understanding informed subsequent project activities. Subtask 1.2--Interviewing Subject Matter Experts (SMEs). To further develop an understanding of the SOM workforce, specifically concerning the current and anticipated future SOM employment needs and the technical knowledge requirements for SOM careers, our team conducted interviews with a representative group of SOM subject matter experts (SMEs). These SMEs had at least 5 years' experience in various SOM careers and were identified through their involvement in one of the following: NCHRP Project Panel 20-86, AASHTO Highway Subcommittee on Systems Operation and Management, and/or NCHRP Project Panel 20-77. SMEs were also selected across diverse and geographically dispersed transportation agencies that further varied in size and community distinction (such as urban versus rural). All experts participated in a 1- to 2-hour telephone interview to discuss opportunities and obstacles they saw in careers in the SOM field. Using the preliminary literature review findings, we developed a protocol comprised of open-ended questions and probes that allowed for investigation of the factors that facilitate and challenge career growth, as well as the specific career paths that incumbents have followed to pursue an SOM career. For example, the protocol included questions regarding the types of jobs, work responsibilities, education, and training which helped SMEs progress toward their current SOM career. In total, we interviewed 24 SOM experts. Exhibit 2 provides the positions and represented agencies of the SOM experts who participated in these interviews.

To generate staffing estimates for SOM occupations, our team mapped SOM-related work functions to standardized occupational codes (SOCs or O*NET-SOC Code) developed by the Employment and Training Administration of the Department of Labor (DOL). This mapping exercise allowed our team to identify DOL standard occupations that include the knowledge, skills, and abilities (KSAs) characteristic of SOM occupations. KSAs are often designated as mandatory or desirable and are defined in the following manner: Knowledge statements refer to an organized body of information usually of a factual or procedural nature which, if applied, makes adequate performance on the job possible. A body of information is applied directly to the performance of a function. Skill statements refer to the proficient manual, verbal, or mental manipulation of data or things. Skills can be readily measured by a performance test or proficient manipulation of things where quantity and quality of performance are tested, usually within an established time limit. Ability statements refer to the power to perform an observable activity at the present time. This means that abilities have been evidenced through activities or behaviors that are similar to those required on the job. Next, our team generated and analyzed current and future occupational estimates for SOM occupations through the use of SOC codes. We conducted this analysis at the national, regional (i.e., Northeast, South, Midwest, and West), and state levels. Our historical estimates provide information on the change in SOM-related occupations during the time period between 2005 and 2010. Our future occupational reports provide information on projected changes for SOM-related occupations between 2010 and 2015, as well as 2010 and 2020. 4
