1. John T. Snow The University of Oklahoma Session 8: Keys to Success: Creating Synergy in All Components of Surface Transportation Weather Applications Where the Weather Meets the Road: Reflections, Synthesis and Editorial Comments

2. Road Weather As An Interdisciplinary Endeavor An interface problem  working at a boundary –On the physical side – between the atmosphere and the surface –On the human side – at the edge of several traditional disciplines Pushing the boundaries in several areas of science, engineering, and technology

3. Need More Innovation In Sensing Systems Snow, ice, rime, frost – presence and accumulation Blowing, drifting snow (also dust, smoke, clouds of insects) Night, dusk and dawn The video camera as a present weather sensor and platform for other instruments –Opportunity to leverage large public investment

4. Plan for Worst Case Life safety issue A robust system is essential  service when it is really needed; tied to credibility –Most needed in worst case situations –Power, comms, servers, C&C  “weather proof” –Argues for a decentralized, distributed system with lots of backup, redundancy Adaptive to the weather, traffic situation

5. Legal Issues Need model legislation package for states, federal government that promotes sharing of data, and addresses directly liability questions Are there legal impediments that hinder transition to operations; private sector involvement?

6. Road Weather Observing Systems In Context 1 Integral part of a regional 4-D meso- and micro (urban)-scale environmental monitoring system –Overlap with other federal programs (e.g., NIDIS) Not a Federal system, but rather a National one  composite of regional/state/local contributions by government, private sector Key federal roles: –Setting standards to guarantee seamless of date/metadata and comms  compatibility, interoperability –Facilitating the leveraging of resources of many partners

7. Need several regional scale test beds –Important step in transition from R&D to operations  proving ground for science, for technology, and for delivery vehicles –Demonstrate effectiveness, seamlessness –Large enough and with a life-time long enough to attract private sector, but not so large as to be unmanageable Road Weather Observing Systems In Context 2

8. ~1000km Major Cities Included: Dallas-Ft. Worth; Houston; Austin; Oklahoma City; Amarillo; Lubbock; San Antonio; Corpus Christi; Shreveport; Tulsa; New Orleans; Mobile; Little Rock; Jackson;........ ~1500km The Chisholm Network: A Prototype Regional Scale Environmental Monitoring System

9. To demonstrate effectiveness of road weather improvements, facilitate nationwide implementation of research results, and provide a seamless stream of road weather information to users and developers One running north- south (e.g., I-35) One running east-west (e.g., I-80) National Demonstration Corridors

10. Movement to Operations “Demonstrate value, leave it to the field” Regional Research Centers –To develop new technologies, foster technology implementation on regional roadways, and facilitate interaction between governments, the private sector, and academia –Should bring together weather and transportation researchers, and practitioners/service providers in the public and private sectors

11. Communicating To Users Social/Psychological/Behavioral Issues –A “last mile” problem: (technology – solvable; response --??? –May be THE central issue, since will control “demand” for services  an issue in common with many other information delivery services –Complicated by the diversity of the audience: e.g., drivers, operators, dispatchers, dontrollers  very different sets of customers Development of “credibility” is one step  perception is reality –Accuracy + recent successes (what have you done for me today?) –Timeliness (latency in link from “obs” to “service” in second, not minutes) A Test
