capacity measures that are at the core of SO&M. Therefore, agencies need <strong>to</strong> institutionalize a<br />

commitment <strong>to</strong> delivering reliable services first and have the right, motivated people with the<br />

necessary resources <strong>to</strong> manage for reliability.<br />

Systems <strong>Operations</strong> and Management (SO&M) refers <strong>to</strong> the broad concept that transportation<br />

agencies can apply a set of known strategy applications <strong>to</strong> maintain and improve highway service<br />

in the face of recurring peak-period congestion and nonrecurring events. There are several best<br />

practice examples of SO&M applications on the part of state DOTs in a few major metropolitan<br />

areas in the United States. They include highly integrated incident management systems, wellmanaged<br />

work-zone control, and innovative traveler information programs. However, these<br />

examples obscure a more general reality: at the statewide level (even in states with the well-known<br />

examples), best practice is confined <strong>to</strong> only a few congested metropolitan areas. Even in those<br />

metropolitan areas, only a narrow range of strategies is applied. Therefore, this generally low level<br />

of implementation offers significant opportunities for improvement.<br />

Agencies are currently more likely organized <strong>to</strong> handle infrastructure improvements as the bulk of<br />

their work. With a SO&M structure in place, implementing and managing the various strategies<br />

and treatments discussed below is much more do-able. Agencies with more comprehensive<br />

strategy applications that are increasingly integrated, standardized, and comprehensive are<br />

distinguished from agencies with less-developed SO&M activities through four key institutional<br />

features (4) :<br />

• Systems <strong>Operations</strong> and Management Awareness<br />

• Systems <strong>Operations</strong> and Management Structure<br />

• Systems <strong>Operations</strong> and Management as High Priority Budget Item<br />

• Identify Opportunities for public-private partnerships<br />

The purpose of these strategies is <strong>to</strong> support transportation agency management <strong>to</strong>wards an<br />

institutional framework that increases and encourages the capability of supporting more effective<br />

management, organizational, and resource allocation structures. These strategies are specifically<br />

aimed at managing nonrecurring congestion.<br />

On the freight side, the literature (8, 9) shows that the effective adoption of in-vehicle transportation<br />

technology is accompanied by a system of regulation. Government often provides policy guidance<br />

<strong>to</strong> allow industry <strong>to</strong> make decisions <strong>to</strong> invest in technology. Significant productivity gains can be<br />

achieved from government-supported performance-based standards for trucks which allow trucker<br />

<strong>to</strong> more-flexibly respond <strong>to</strong> business needs.<br />

Table 6.2 provides a summary of the key strategies for the examples presented in this section.<br />

Note that all the strategies within this category are essential for managing the sources of<br />

congestion.<br />

Agencies need <strong>to</strong> moni<strong>to</strong>r travel-time reliability problems as they arise and <strong>to</strong> prepare <strong>to</strong> respond.<br />

Problems can be addressed by tracking travel trends, identifying innovative solutions, and acting <strong>to</strong><br />

implement those solutions. Smart use of resources, driven by good information and the ability <strong>to</strong><br />

decide and act, are all parts of the solution. Agencies may wish <strong>to</strong> make a case for increasing<br />

transportation funding levels that promote economic development and safety. Agencies may also<br />

train and elevate a new cadre of professionals who are focused on service quality, system<br />

management and technology innovation.<br />
