Intelligent Traffic Signal Control System SW-UTC2010 Overview

system absorbs the advantages of Australian system (SCATS) and British system (SCOOT) in the aspects such as controlling model and strategy, system working mode and controlling mode, etc. The core control algorithm of the system not only absorbs the flexibility of selective configuration of SCATS system scheme, but also learns from the advantages of the real-time prediction and optimization of SCOOT system, which can make a good balance between automatic optimization of the system and experience configuration of traffic engineer, and can better meet the characteristics of Chinese mixed traffic and traffic control requirements of public security traffic administration department.

 

System Structure

The software technology of the system is the advanced software development technology with the most advanced networked, distributed, object-oriented and component software and others. The system has the very high maintainability and system reconstruction characteristics, and the system can conduct flexible configuration and reconstruction according to the different control scales and operation platforms.

6. Journal record and analysis

It records fault and state of running software and harSWare, and analyze system efficiency and performance. When system running out of way, it could assist locating source of error.

7. Traffic flow statistics and analysis

The    center software makes record, statistics, inquiry and analysis for detecting data.

       8.System users’ accounts management

       According to different priority levels of clients, the system display different operation surface and make different system operation.

       9.Database backup

       Automatically backup critical data from the database, and manually reserved all the database.

      System Features

     Run-time environment is WINDOWS operating system, with fully distributed network environment, easy installation, convenient usage and maintenance, and great expansibility.

     The setting of system operation mode and control mode is suitable for the complex characteristics of mixed traffic in our country, and automatic optimization control and          flexible means of intervention bring the system great practicability.

     The system adopts the advanced object-oriented and modular software development technology, and has flexible system structure and higher portability.

     The system has transparent interface, and great secondary development ability.

     The system has strong macroscopic and microscopic traffic statistics and report printing function.

     The centralized log management of the system is convenient for fault location and benefit analysis.

     The system and all front-end equipment are of intellectual property rights, and have higher performance-price ratio.

     The system supports serial port, cable network, 3G wireless network, etc.

     The system supports coil, video, microwave, terrestrial magnetism and other testing equipment, and can share with the electronic police.

 SW-TSC2010C brief introduction

 SW-TSC2010C central coordinated signal control machine is the structure simplification version of SW-TSC2010, simplifying functions not commonly used and improving the cost  performance. The product adopts the embedded harSWare and CAN bus structure, stable and reliable, and easy to expand. It has the largest 48-way lamp driving output, and has  many intelligent control functions such as single-point induction, single-point optimization, cable-free green wave drive-by-wire, pedestrian request button, tactical  changes and others, so it is very suitable for the particular traffic condition and traffic management mode in our country. It complies with GB25280-2010 - A level.
