With the acceleration of the national informatization process, the informatization of the transportation industry is showing a momentum of rapid progress. Guangdong Province, located in a developed coastal area, has played a leading role in the construction of highway network toll information. As an ITS system integrator, Guangdong Xinyue Transportation Investment Co., Ltd. has successfully implemented a highway networked toll system and related software and hardware systems on expressways in the five regions of Guangdong Province, including Western Guangdong, Eastern Guangdong, Northern Guangdong, Shenzhen, and the Pearl River Delta. And so on, and successfully carried out regional network toll; at the same time, summed up a set of highway network toll information construction overall solution, and successfully implemented in some areas.
Overall solution
The overall solution for the informatization construction of highway networked tolls in Guangdong Province includes systems such as networked tolls, networked tolls and escape fees, networked tolls emergency handling, road monitoring, decision-making assistance, and information security. The following briefly introduces the solutions and applications adopted by these systems.
◆Road network combined toll collection system (MTC+ETC)
The road network combined toll system realizes the computer management of the toll collection of passing vehicles on the road network by using non-contact IC cards (paper coupons as an alternative) as a pass. It is a closed expressway toll collection monitoring, control, A comprehensive information processing software system integrating auditing and management.
The starting point for the design of the combined charging technology scheme has fully considered the applicable conditions of the ETC automatic electronic charging method and the IC card manual semi-automatic charging method. The two technologies are organically combined through the mode of two-piece electronic tags and dual-interface CPU cards. In the entire road network, the most economical and effective means are used to achieve comprehensive goals such as accurate toll collection, traffic flow, and efficiency improvement. The combined toll technology solution truly realizes the compatibility of MTC toll and ETC toll. Users can choose to pass through MTC lane or ETC at the entrance and exit of the expressway by using a Yuetong card (stored value card or debit card) and two-piece electronic tags. Lane.
The biggest advantage of the combined network toll collection system is that it utilizes system resources, saves investment, and has a good application prospect in the field of highway toll collection in my country. The system has been successfully applied in the five areas of Guangdong Province’s western Guangdong, eastern Guangdong, northern Guangdong, Shenzhen, and the Pearl River Delta and the expressways of the whole province of Shanxi Province. It has been appraised by the Guangdong Provincial Department of Science and Technology and is considered to have reached the domestic advanced level.
◆Networked charging and anti-escape fee system
With the continuous expansion and improvement of the highway network, the distance of network tolls is getting longer and longer, and the corresponding tolls will increase. Toll evasion is a very prominent problem. In order to deal with the new problem of evasion and cheating under the new situation of network tolling, and to ensure the orderly progress of toll collection, the network toll prevention and evasion toll management system combined with the characteristics of expressway network toll is the first to propose a new type of anti-cheating using electronic and information technology in China. The technical solution integrates technologies such as dynamic timeout routing, collision principle recognition, evidence chain management, automatic license plate recognition system, card box management, etc., and establishes an anti-cheating system in a networked charging environment, which significantly improves the ability to detect evasion of tolls And efficiency.
At present, the system has been successfully applied in the northern area of Guangdong Province, and successfully passed the result appraisal of the Guangdong Provincial Department of Science and Technology. It is believed that the system is novel in design and advanced in technology. It is used in expressway network tolls to prevent and restrain toll evasion and inspection packages. Licensed cars have reached the leading domestic level.
◆Networked charging emergency handling system
The expressway emergency system is aimed at the need of expressway functional management departments for rapid response to various traffic accidents, holiday peak traffic, major disasters and other emergencies. It strengthens the supervision and management of subordinate expressways by functional management departments, and combines the current Advanced digital video, broadband communication, microelectronics integration and other technologies, targeted development of integrated solutions.
This system uses digital remote monitoring technology to enable users to monitor any monitoring pictures of subordinate road sections in real time, and they are well aware of various traffic conditions.
At the same time, for various emergencies that occur on the expressway, the system can be used to understand the on-site situation for the first time, which provides a guarantee for remote command and coordination. The emergency system collects traffic flow data and toll information of each road section in real time, and is processed by the data mining engine. It can learn the traffic status of each toll station in the subordinate road section in advance, and according to the preset warning value, it can check the toll station that has traffic jam. A warning message is issued, and it is automatically switched to the monitoring screen. It enables the functional management departments to conduct overall command of traffic evacuation at the level of the whole province.
For toll gates with traffic jams and road sections that require emergency dredging, emergency toll collection plans can be activated. The portable toll collection machine and handheld IC card toll collection machine supporting this system can increase the processing capacity of manual toll collection and speed up the efficiency of vehicle traffic; Monitoring, key IC card verification and other means can effectively prevent human cheating.
The emergency system is also a traffic emergency information release platform for the whole province. Through the information release website, the emergency information, traffic guidance information, travel route, traffic flow and other information on the expressway can be released to government departments, public security, and the public at the first time. You can also use the SMS platform to send mobile phone text messages and live images (MMS function) to senior leaders and road section managers, so that relevant personnel can quickly learn about the occurrence of emergencies no matter where they are, effectively improving the comprehensiveness of emergencies Coordinating processing capabilities.
At present, the six major regions of Guangdong Province, including Western Guangdong, Eastern Guangdong, Northern Guangdong, Shenzhen, Pearl River Delta, and Guangzhou, have activated emergency response systems to varying degrees. Emergency toll collection plans have been activated for traffic congested toll stations. Portable toll collectors and handheld IC card toll collectors speed up the efficiency of vehicle traffic, improve social satisfaction, and increase economic benefits.
◆Road network monitoring system
The highway network monitoring system is a kind of detection equipment installed along the highway to collect, analyze and process relevant traffic, environment and equipment status data, and make decisions according to certain rules; through information release equipment and traffic control equipment A comprehensive traffic command system integrating detection, control and management for road traffic command and dispatch.
The system can accurately count road traffic data; effectively monitor road traffic, weather, and environmental conditions; and timely grasp road operating conditions. At the same time, when an abnormal situation is discovered, the information release equipment and traffic control equipment can be used to perform speed limit, guidance, transfer, diversion, ramp adjustment, road closure and other traffic control processing, so that the highway traffic flow is always kept at the best The state of free flow, timely detection and handling of traffic accidents, reduce the incidence of accidents, and improve road traffic capacity.
As one of the three major mechanical and electrical projects of expressways, this system has been fully applied in expressways, tunnels, bridges and culverts in various regions of Guangdong Province.
◆Road network operation management and auxiliary decision-making
Network tolls not only improve the service quality and business operation quality of expressways, but also bring a large amount of high-quality operating data to managers. These operating data reflect a lot of information, such as toll income status and toll ratio status. , The distribution of traffic flow, the proportion of traffic flow composition, the traffic load status of each section and the work status of toll personnel at each station, etc. This information has important reference significance for the improvement of service quality, the effective use of resources, and the effective maintenance of road surfaces. However, what does not match the rapid development of these basic software and hardware facilities is that there are currently no effective tools to enable highway managers to easily extract information that is valuable for management and operation from operating data. In response to this situation, an auxiliary decision-making function has been creatively added to the networked charging system.
◇Online analysis and processing tools enable analysts, managers or executives to analyze a large number of historical operating data from multiple angles for the same subject, so as to quickly and interactively draw verification analysis conclusions for decision support.
◇Advanced analysis tools, providing dynamic trend analysis capabilities and static comparative analysis capabilities. Among them, dynamic trend analysis can enable managers to grasp the laws of various objects in expressway operations; static comparative analysis can clearly reflect the differences and similarities between different states to users.
◇Enterprise management assistant tool, which automatically acquires knowledge in massive data, and provides a practical, easy-to-use, and highly instructive management model to provide knowledge support for managers’ decision-making.
◇ Macro analysis tools can show managers an overall and general picture of operating conditions so that managers can grasp the overall situation.
◇Build a highway data warehouse to make it an open and easily expandable highway public information platform, which can effectively isolate applications and specific data sources, so that related applications can remain stable, and it is easy to integrate data in new applications.
As a subsystem of the networked toll collection system, the system has been applied to the 5 districts of Guangdong Province and the highways of Shanxi Province together with the networked toll collection system. It has achieved good application effects and provided certain decision-making support for highway operation and management personnel. .
◆Network Information Security System
With the continuous development of informatization construction of highway management companies, the continuous improvement of information integration between departments, and the continuous development of the public’s need for the release of traffic information resources, in the future, various application systems will inevitably need to be integrated to form a unified management company Internal network, and release rich traffic information resources to the outside world on the INTERNET through the company portals of various road sections. With the development of enterprise informatization and the realization of information resource sharing, network management and information security have naturally become important and inevitable topics.
In view of the hidden dangers of information security of different highway application systems, it is necessary to establish a security protection system with a “multi-level protection” security concept, and fully integrate the network management system to achieve effectiveness in three aspects: external intrusion, internal operation, and business management Management and monitoring. Mainly include the following functions: can monitor the network dangerous situation at any time, isolate the dangers related to system information security, and can control the danger to the minimum range; implement identity authentication, permission setting, and effective management of resource access; Dynamic or static audit of resources or users; automatically generate alarms or event messages for violations; implement password management (such as operator password authorization) to control unauthorized operators; key management; Related servers should be provided with key lifecycle, key backup and other management functions; redundant backup is to increase the safety factor of the network, and redundant backup of key information.
The system has been implemented in the western and northern regions of Guangdong Province, and has achieved a good anti-virus effect, enabling each application system to share information in a secure network environment.
The results and experience of the implementation of the plan
Through the implementation of the above-mentioned system engineering, the construction of highway network toll informationization in Guangdong Province has achieved remarkable results and obtained great economic and social benefits. Through the implementation of informatization construction projects, the management level and traffic efficiency of the road network have been improved, unnecessary economic losses have been recovered for the country, and economic benefits have increased significantly. At the same time, through the implementation of the emergency system and the information release system, more high-quality and efficient information services will be provided for public travel, and social satisfaction has been greatly improved.
However, the information construction project of expressway operation management is a comprehensive and complex task. In the process of project implementation, it is necessary to consider the coordination and cooperation of various sub-items and types of work, as well as the cross-construction of various systems and stages; both To ensure the implementation schedule, it is necessary to strictly implement relevant technical and quality management measures. Through the implementation of a series of informatization construction projects, we have also gained certain experience, that is, unified planning, step-by-step implementation, and localized services.
◆Unified planning
The implementation of the highway informatization construction project is a complex project, so the overall plan must be carried out first, and then it can be implemented step by step. Proceeding from actual needs, we will use modern management methods to standardize the management of expressways to improve the accuracy of information expression and the rationality and standardization of business processing. Starting from the strategic goals of the enterprise and the overall planning of the informatization project, formulate the overall plan and goals of the highway informatization construction. The implementation of the information system should be guided by the overall plan, the entry point for the implementation should be selected, starting from the areas where improvement is most needed, and the various modules of the system should be implemented step by step and stage by stage.
◆Step by step implementation
In order to be able to implement the information system smoothly, a roadmap solution was proposed. Roadmap is a project plan that describes in detail what stage and what to do and how to do it. Roadmap includes the stages of project preparation, business blueprint, requirement configuration, final preparation, operation and support.
◇The project preparation stage mainly involves the start-up meeting of the project, including the organization of the project, rough project planning and initial training.
◇Business blueprint stage, the purpose is to record customer needs, customers and demand analysts build their own business blueprint together to describe and analyze the business of the enterprise.
◇The requirement configuration stage is mainly based on the processes and problems recorded in the business blueprint, and configure the basic system according to the business blueprint navigator (business blueprint template) provided by us, delete unnecessary processes, and add new customer-oriented net value-added chain.
◇The final preparation stage includes the combined results of all the previous stages. Its purpose is to prepare the final system for use in the company, including the final system test, end user training, data entry, etc.; another task Is to establish a start-up strategy.
◇In the operation and support phase, the system needs to be reviewed to ensure that the system fully supports the business environment. Therefore, it is necessary to check business processes and technical parameters, and communicate with end users to understand the status of all aspects of system operation. At this stage, performance evaluation of the profits of the enterprises running the new system is also required to monitor the return on investment of the system.
◆Localization Service
The successful implementation of the networked charging information system also depends on having dedicated technical personnel to provide users with technical support within the scope of the system, including timely response to user problems, hotline Q&A support, and on-site problem solving.
Actively implement a localized service strategy, establish a professional service team locally, support after-sales service and maintenance of products, and achieve rapid response.
