Definition, Objectives and Importance of ITS
Intelligent Transport Systems (ITS) apply information and communication technologies to transport. Computers, electronics, satellites and sensors are playing an increasingly important role in our transport systems. ITS as such are instruments that can be used for different purposes under different conditions. ITS can be applied in every transport mode (road, rail,
Infrastructure of Intelligent Transport Systems
ITS infrastructure is composed of many systems that work together to perform integrated functions. ITS infrastructure includes the following systems: 1. Traffic signal control systems 2. Freeway management systems 3. Transit management systems 4. Regional Multi-Modal traveler information system 5. Emergency management systems 6. Electronic toll
Traffic Information Dissemination Media
TV (full time versus conventional news cast), Easy access to traffic hotspots on UW2.TV, Channel 76 on digital cable, Low cost to public (user), Higher cost to disseminator, Short duration message, Misses details, some geographic areas, Only for pre-trip information, Generally not available on demand. Radio Low cost to public (user), Short duration message
Types of 'Timing of Information Delivery'
Information differs depending on what you want / expect to be done with that information General information (congestion/accident ahead) Routing (use alternative routes / modes – usually needs to include specific directions Potential effect is based on when you provide the desired information: Change route, Change mode (if P&R is viable alternative), Give up trip
Advanced Traveler Information System
ATIS for arterials provides information on arterial conditions (e.g., travel speeds, travel time, incidents) to motorists through such media as websites, radio, television, or personal devices. This limited dissemination is in part due to the lack of surveillance on arterial streets. Another challenge is the absence of a commonly understood method of describing
ITS Architecture / Hierarchy / Layers
It is a conceptual design that defines the structure and/or behavior of an integrated Intelligent Transport System (ITS). ITS Architecture provides a framework to guide the planning and deployment of ITS technologies. The program facilitates the ability of jurisdictions to operate
