Operations, decision support, electronic toll collection, emergency rescue and other fields; the travel process involved includes pre-travel, in-travel and return transportation services, etc.; the service levels involved include basic services and special services.
System function and framework: The Shanghai World Expo Intelligent Transportation System is composed of “one center, six application systems”, and the overall structure is shown in the figure:
World Expo Intelligent Transportation System Application Framework
One, a center
The Shanghai World Expo ITS Center is the overall control and coordination center of each application system, which realizes the interconnection, data exchange and sharing of each application system, and performs data exchange and connection with the Shanghai Transportation Comprehensive Information Platform and other ITS systems. The nerve center that guarantees the effective management and information service of Expo traffic.
Two, six systems
1. The Expo Travel and Transportation Comprehensive Information Service System, referred to as “travel information”
The comprehensive travel information service system is to provide comprehensive traffic information covering all modes of transportation for tourists. It can provide visitors with different travel modes, different places, and different preferences for a comprehensive understanding of the traffic conditions of the World Expo, before they travel, during travel, and in the park. Throughout the process, comprehensive traffic information can be obtained, and services can be provided in a simple manner such as “one website, one phone”. The comprehensive travel information service system is the most basic transportation information service provided by the Expo organizer for tourists. The Expo Travel Comprehensive Information Service System is composed of the following subsystems:
(1) Expo transportation website
(2) Traffic information service for mobile phone users
(3) Expo hotline
(4) Traffic information service methods such as dedicated channels for traffic radio stations and TV stations
2. Expo traffic monitoring system, referred to as “traffic monitoring”
As an integral part of the intelligent transportation system, the intelligent traffic monitoring system plays a huge role in ensuring the safety and smooth flow of urban traffic. It can be used as a window to understand traffic conditions and public security conditions, and is an indispensable subsystem of the public security traffic command system. The purpose of establishing a video image monitoring system is to timely and accurately grasp the traffic of vehicles and pedestrians around the monitored intersections, road sections, and traffic security conditions. The area of traffic video surveillance is mainly the main roads in the city. The focus is on intersections, road sections and accident-prone points with heavy traffic. All surveillance video information is sent to the monitoring center. This feature determines that the traffic video surveillance network is point-to-multipoint decentralized In a network structure, each point is close to or far away from the monitoring center, and the far point is as long as ten kilometers to dozens of kilometers. The system consists of a three-level monitoring system with high-performance, multi-faceted detection means, intuitive digital detection display, image monitoring, perfect emergency telephone alarm function, and a monitoring system that can issue warnings and induce information in a timely and dynamic manner.
3. The Expo Intelligent Public Transportation System, referred to as “smart bus”
Public transportation carries more than 85% of the Expo direct passenger flow and is the most important mode of transportation for the Expo. The public transportation information service system is based on the public transportation operation dispatching information system, and provides convenient, efficient, comprehensive and thoughtful, interactive and transparent transfer and connection information services, arrival forecasts and estimated travel time information services for the majority of tourists who use public transportation. , Strive for public transportation to be fast, punctual, convenient and comfortable, and to minimize delays and congestion caused by poor information. The Expo Public Transport Information Service System includes four sub-systems: rail transit information service system, Expo bus dedicated line information service system, water bus information service system, and taxi information service. Expo public transportation should be separated from normal public transportation as much as possible in terms of transportation organization and information services. The two passenger flows should be appropriately separated in time and space, and differentiated guidance services will be implemented. This will greatly improve operational efficiency and protect the World Expo. Convenient and unobstructed transportation for tourists. In order to effectively organize and manage public transportation and guide the public transportation passenger flow of the Expo in an orderly and rapid manner, these public transportation information systems that provide specific services for Expo visitors must be planned and constructed in a unified manner and incorporated into the planning and construction of the Expo transportation information service system framework. Scope.
4. The Expo Transportation Decision Support System, referred to as “decision support”
According to the demand analysis of the Shanghai World Expo, the traffic decision-making system will solve the following traffic problems: conduct traffic flow surveys, predict traffic flow, analyze congestion attributes, make decisions on traffic congestion, command decisions on emergencies, and provide relief based on traffic conditions Stressful Expo strategy, etc. Among them, flow monitoring, dredging decision-making and decision-making are mainly realized by the human-computer interaction subsystem calling models in the model library, and model library management, pre-plan library management, and strategy library management are implemented by various subsystems. The system framework is shown in the figure.
