It can be challenging, he continued, to convince states to think about sustainable asset management. MAP-21 defines asset management as "a strategic and systematic process of operating, maintaining, and improving physical assets, with a focus on engineering and economic analysis based upon quality information, to identify a structured sequence of maintenance, preservation, repair, rehabilitation, and replacement actions that will achieve and sustain a desired state of good repair over the lifecycle of the assets at minimum practicable cost." MAP-21 requires that each state "develop a risk-based asset management plan for the National Highway System to improve or preserve the condition of the assets and the performance of the system." Gaj commented that this plan must include 1 The website for MAP-21 is https://www.fhwa.dot.gov/map21/.

There are also safety applications on the infrastructure side -- for example, data about timing of traffic light phases or the geometry and surface conditions on a curved road can be sent to the vehicle, and the vehicle understands its own dynamics and can make a decision about the appropriate speed to engage at that particular moment. If vehicles encounter 2 The website for the Federal Highway Asset Management program is https://www.fhwa.dot.gov/ asset/.

He estimated that it would take 40 years for a full build-out of the connected vehicle technology, if and when the National Highway Traffic Safety Administration develops a mandate. In response to a question from a participant about safety and the enforcement of traffic laws, Andersen noted that 35,000 people die each year on highways, and the Federal Highway Administration and all of the Departments of Transportation work hard to eventually reduce this number to zero.

Andersen concluded by encouraging workshop participants to go to the Intelligent Transportation Systems Joint Program Office website5 for more information about and training on connected vehicles. WORKSHOP WRAP-UP Matthews recapped his overview of national defense programs and reiterated his confidence in the ability of the current infrastructure and the current industry to deliver forces from their installations to their ports.

De la Garza noted that the most recent American Road and Transportation Builders Association newsletter cited 59,000 deficient bridges and wondered whether STRAHNET has the locations of those deficient bridges in place. Matthews said that that is an issue that needs to be reviewed, and he reiterated the importance of considering the many levels of potential effects when designing and acquiring new systems.

He also encouraged the Federal Highway Administration to spread this message so that there is political support for areas that need to be fixed. Andersen reiterated that the Federal Highway Administration does not own roads, and so he wondered whether the Corps evaluates proposed changes to AASHTO's Green Book (the guide for road design)

Li expressed concern that more durable roads could lead to faster driving, given that there will be fewer reconstruction zones. However, he emphasized that such concerns should not stop innovation.
