Guidebook 47 Transportation Case Studies 1 Study Case Adaptive Control Software Lite Value to Sell: Publicprivate partnerships that advance signal software development. Context and FHWA would pay half of the development costs In the mid-1990s when new technologies were for the "bridging" software to connect the old and booming, one of the innovations that changed the new systems for each participating manufacturer. field was adaptive control technology. Adaptive This incentive offered a big reward--better control systems "teach" themselves by measuring product and low development cost--for the their own performance and adapting to improve risk of participating in the research with fellow based on changing conditions, making them good competitors. candidates to deal with the increasing congestion Content in urban areas. The Federal Highway Administration (FHWA)/Turner-Fairbank Highway Research Center The FHWA communicated that ACS Lite was the embarked on research to improve traffic signal best way to significantly reduce congestion because control. The research yielded a program called it was designed to keep the signal settings and Adaptive Control Software (ACS). ACS was well timing current. A second message was that ACS Lite, suited for large urban areas. However, in areas with through the incentives offered to manufacturers, small to medium population densities, installation could serve as a cost-effective retrofit for existing and maintenance costs kept the ACS system from systems, while requiring minimal equipment or gaining wide acceptance. Given these barriers, replacement for its use. FHWA identified a need to adapt the software to be Channel and Style suitable for use in small and mid-sized cities. The result was a new software tool called ACS Lite. The channel and style used in this case were personal, conversational contact. The FHWA had to Strategy reach out to policy makers, technical researchers, Two strategies were used to develop ACS Lite. First, and industry leaders to convey the industry-wide developers had to convey the message that ACS Lite benefits of ACS Lite and to gain acceptance of the was a product with the ability to solve a problem on new software. By communicating directly with a national scale. Second, the FHWA research team decision makers and industry influencers, the FHWA offered an incentive to the major industry players: was able to successfully carry out its strategies. they could obtain the ACS Lite software at no cost,
