Abstract: Abstract The motivation for this chapter stems from a 15-year collaboration between the California Department of Transportation (Caltrans) and the Western Transportation Institute, and now Utah State University. Ian Turnbull, recently retired from Caltrans, set the standard of “accurate, timely and reliable” for all projects he was involved with, particularly those in remote, rural areas of California, and related collaborations. Ian’s team, now headed by Jeremiah Pearce, is responsible for the operation of a vast field sensor network and the provision of weather sensor data, CCTV images, chain control messages, changeable message sign (CMS) messages, and just about every other type of traveler information related to Caltrans District 2, particularly in remote, rural areas of Northeastern California. In turn, Sean Campbell, also from Caltrans, makes this and similar data from the rest of the state available to third-party providers of traveler information and other related applications. The experience gained in working with Ian, Sean, Jeremiah and others on the provision of traveler information and the development of systems for DOT operations and maintenance personal has been invaluable for recognizing the need for and the challenges of providing quality spatio-temporal data.
