Failures of traffic signals can lead to crashes and loss of productivity. As the road network gets more congested, the sustained operation of traffic signals becomes even more critical. The effective management of traffic signal assets therefore plays a vital role. This study developed guidance in the management of traffic signal assets to maximise level of service at a minimum life-cycle cost; mitigate risks to road users; and continually improve planning, maintenance and operations. To provide guidance, a template for an asset management strategy for traffic signals was developed which focusses on achieving a well-defined and broadly accepted level of service, recognises and manages risks to road users and assets, and uses whole-of-life costs as its criterion. Performance monitoring, review and feedback processes are also suggested to identify improvements in the planning process.

This issue contains 13 papers concerned with traffic control devices, visibility, and highway-rail grade crossings. Specific topics addressed include: “vehicle entering when flashing” signs; countdown-only pedestrian change interval displays; driver perception-reaction time under rainy or wet roadway conditions at the onset of yellow indications; improved dilemma zone identification; left-turning driver behavior during the permissive interval of protected-permissive operation; and expectancy violations on frontage and conventional roads at interchanges. Other topics discussed include: illuminance from LED luminaires; the impact of modern headlamp technology on design criteria for sag vertical curves; background complexity of overhead guide signs; nighttime visibility of in-service pavement markings; replacing roadway lighting with new lighting technologies; injury severity of motor vehicle drivers at highway-rail grade crossings; and advanced devices for preventing crashes and gate-breaking incidents at highway-rail grade crossings.

Flyer for Transportation Asset Management Conference, May 8, 2013, East Lansing, MI.

This webinar focused on chapter 2 of the AASHTO Transportation Asset Management Guide. The focus of this chapter is on setting direction for TAM. Steps covered: Setting agency goals and objectives; Self-assessment and gap analysis; Defining scope of TAM in the agency. Includes case studies of Iowa, OH, and North Dakota. Presented in Webinar: The Transportation Asset Management Book Club.

Discusses Asset Management Needs / Drivers, the Systems Required to Support Asset Management, and business processes for design and integration

Describes how to develop, implement and maintain standards, recommended practices and design guidelines to achieve safety, reliability and efficiency in transit system design, operation and maintainability.

Introduces key asset management concepts, presents a transit specific asset management framework and business model that defines and communicates “best practice” and provides guidance to advance asset management maturity within any agency. Describes tools and case studies that can support implementation.

UTA recognized the need for an overall Asset Management System and for outside assistance to develop a comprehensive system.

The final report in a series of five reports designed to familiarize members of the transportation community with risk and its role in the decision making process. This report addresses resilience, and how risk-based asset management can help an agency to approach external threats to their assets.

The fourth of five reports designed to familiarize members of the transportation community with risk and its role in the decision making process. This report details risk management of critical assets.
