SHRP 2 L11: Final Report<br />

Institutional Challenges<br />

To effectively manage the transportation system with a focus on reliability and <strong>to</strong> achieve the<br />

future concept of operations, transportation agencies will need <strong>to</strong> adopt an institutional structure<br />

that is more multidisciplinary, exercise horizontal integration across all focus areas, and facilitate<br />

effective interagency collaboration. The critical change will be <strong>to</strong> focus on systems operations,<br />

rather than on the his<strong>to</strong>rical focus of roadway expansion. A true focus on maintenance and<br />

preservation of the existing system is also essential <strong>to</strong> maintain mobility, since a deteriorating<br />

system could make it exceedingly difficult <strong>to</strong> manage reliability. Because it is unlikely that enough<br />

transportation revenue will be available in the next 20 years <strong>to</strong> replace and res<strong>to</strong>re all aging<br />

infrastructure, infrastructure moni<strong>to</strong>ring will be crucial. Delays due <strong>to</strong> <strong>to</strong>ppled luminaire poles,<br />

traffic signal light outages, bridge expansion, joint deterioration, potholes, and more serious<br />

structural failures could be major contribu<strong>to</strong>rs <strong>to</strong> reduced system reliability in the future.<br />

Infrastructure moni<strong>to</strong>ring systems are likely <strong>to</strong> be a critical part of any attempt <strong>to</strong> assure<br />

transportation system reliability. These moni<strong>to</strong>ring systems can also be used for security-oriented<br />

transportation infrastructure protection.<br />

Systems Management<br />

There are good reasons for systems management <strong>to</strong> be a business practice with supporting<br />

performance measures and outreach materials that report on the benefits of the program. Since<br />

many highway systems of the future are likely <strong>to</strong> be greatly dependent on pricing systems for<br />

revenue, congestion management, and data collection, it will be crucial that the system is managed<br />

with these aspects in mind <strong>to</strong> provide value <strong>to</strong> the traveler. A mo<strong>to</strong>rist who pays a premium <strong>to</strong><br />

arrive at a destination at a specified time (i.e., who pays for a trip of a certain travel time and<br />

reliability) will be a very disgruntled cus<strong>to</strong>mer if the system fails <strong>to</strong> deliver and the trip takes<br />

longer than expected. Depending on the operating policy, the <strong>to</strong>ll or fee for service may need <strong>to</strong> be<br />

refunded. Opera<strong>to</strong>rs of systems that consistently meet mo<strong>to</strong>rists’ expectations and deliver the<br />

expected value can be rewarded. Agencies may wish <strong>to</strong> consider ways <strong>to</strong> measure cus<strong>to</strong>mer<br />

satisfaction and reward efficient system management (possibly with more resources <strong>to</strong> further<br />

improve operations) and penalize inefficient system management (by sending non-performers <strong>to</strong><br />

lower status jobs as is done in the case of non-performing sports team managers.)<br />

Reliability will become even more crucial <strong>to</strong> freight movers. As a result, freight mobility deserves<br />

at least as much consideration as personal mobility. Agency planning procedures will need <strong>to</strong> look<br />

at a wider of range options, such as truck-only lanes, micro-cars, or other vehicles powered by<br />

alternative propulsion systems.<br />

The “Mobility” Agency<br />

This focus on system operations means that many agencies in the future will not only be concerned<br />

with managing the infrastructure that moves vehicles or people from A <strong>to</strong> B but also focus on the<br />

movement of information from A <strong>to</strong> B. Providing the information needed by commuters <strong>to</strong> make<br />

informed decisions on telecommuting based on real-time traffic and infrastructure conditions is an<br />

example of this change in emphasis. The “mobility agency” is envisioned <strong>to</strong> support mobility of<br />

people, things, and ideas. For some modes, it would be an infrastructure owner-opera<strong>to</strong>r, for others<br />

it would be a service provider or a provider of information only. In the new world of cus<strong>to</strong>mer<br />

orientation, this agency is expected <strong>to</strong> be even handed in providing service and advice. Thus, it<br />

would never be an information carrier, like a cell phone company, but it might tell people that<br />

telecommunications is an option. It would not be a central controller of land use, but it may inform<br />
