  1. A Distributed Smart Signal Architecture for Traffic Signal Controls Dustin DeVoe Richard Wall, PhD University of Idaho Moscow, ID USA

  2. Motivation for Distributed Control • Reduce Complexity • Enabling technologies • Promotes open architecture • Encourages development of new technologies and services • Overcome legacy technology and practices • Less expensive installation • Easier to tune • Reduce misinformation • Improve service to all users Univerity of Idaho Engineering

  3. Research Goals • Identify Suitability • New control devices • New instrumentation • Identify Advantages • Access • Safety • Reconfigurable • Upgrades Univerity of Idaho Engineering

  4. Evolution of Traffic Control Mechanical Switch Traffic Controllers of 1924 Univerity of Idaho Engineering

  5. Evolution of Traffic Control NEMA TS1 Standard - 1976 Univerity of Idaho Engineering

  6. US Approach - Distributed Control? NEMA TS2 Standard - 1992

  7. Application of Distributed Standard • Implementation of IEEE 1451: Plug and Play Arbitrary Network Univerity of Idaho Engineering

  8. Current Traffic Control Design NEMA TS2 Controller System NTCIP: National Transportation Committee for Intelligent Transportation Systems Protocol Web Based Configuration Interface Univerity of Idaho Engineering
