Unformatted text preview: Final Lecture Intelligent Transportation Systems (ITS) and the Impact of Traveler Information & Emerging Themes in Transportation Economics and Policy Moshe Ben-Akiva 1.201 / 11.545 / ESD.210 Transportation Systems Analysis: Demand & Economics Fall 2008 Outline: ITS ● Introduction to ITS and its applications ● Dynamic traffic management ● The impact of traveler information ● Modeling and simulation for dynamic traffic management ● DynaMIT – Travel behavior models – Data and calibration ● Evaluating the impact of traveler information ● Appendices: Examples, Case Studies Useful reference on ITS: http://www.itsoverview.its.dot.gov/ 2 Introduction ● Intelligent Transportation Systems (ITS) combine advances in information systems, communications, sensors, and advanced modeling and algorithms to improve the performance of surface transportation. 3 Benefits of ITS ● Travel – Decreased travel time – Improved safety and security – Increased reliability – Decreased cost – Improved trip planning – Improved emergency response 4 Benefits of ITS (cont.) ● Economic – Increased productivity – On-time delivery ● Environmental – Decreased air pollution – Fuel savings 5 ITS Applications ● Advanced Transportation Management Systems (ATMS) – Network management, including incident management, traffic light control , electronic toll collection, congestion prediction, and congestion-ameliorating strategies. ● Advanced Traveler Information Systems (ATIS) – Information provided to travelers pre-trip and during the trip in the vehicle. ● Advanced Vehicle Control Systems (AVCS) – Technologies that enhance driver control and vehicle safety. 6 ITS Applications (cont.) ● Commercial Vehicle Operations (CVO) – Technologies that enhance commercial fleet productivity, including weight-in-motion (WIM), pre-clearance procedures, electronic log books, interstate coordination. ● Advanced Public Transportation Systems (APTS) – Passenger information and technologies to enhance system operations, including fare collection, intramodal and intermodal transfers, scheduling, and headway control. ● Advanced Rural Transportation Systems (ARTS) – Mostly safety and security technologies for travel in sparsely-settled areas. Reference: Sussman, Joseph M., Introduction to Transportation Systems , Artech House, 2000. 7 ITS Applications (cont.) ● This lecture will focus on dynamic traffic management , which integrates ATMS (network management) and ATIS (traveler information) applications. 8 Dynamic Traffic Management 9 Traffic Management Center Surveillance Control Information Traffic Conditions Supply Travel Demand Information Loop Control Loop Impact of Traveler Information ● Provide information to road users before and during a trip (through in-vehicle technologies) ● Public transport users can also benefit from information provided through: – Vehicle location systems – Scheduling systems (e.g. online journey planners) – Scheduling systems (e....
