23. atlas – can re-locate sensors where most needed (in case of monitoring congestion points) Each sensor is not constrained to be located at one point – can provide information on the WWW FRAMEWORK FOR ITS + REMOTE SENSING SO, HOW DOES REMOTE SENSING HELP? – can move with the “flow” (in security applications the sensor can follow suspicious movements) Can provide up-to-date traveler information, especially at disruptions and incidents – can provide information to en-route motorists in in-vehicle ATIS

24. atlas – for evacuation management during floods and disasters Can be deployed and re-deployed when fixed detectors fail FRAMEWORK FOR ITS + REMOTE SENSING SO, HOW DOES REMOTE SENSING HELP? (contd.) Can get better spatial measures such as turning ratios platoon dispersion, discharge rates, and travel times – better measures for wide-area dynamic traffic management (DTA-ATIS) – even better OD route volumes for transportation planning – for incident management

25. atlas  Acceptance -- by users, by providers, by operators. CHALLENGES There are three major challenges  Technical -- to integrate these sensors, computers, communication systems, people, infrastructure  Cost: Will the benefits justify the costs?
