【摘要】：随着新疆各地区交通需求迅速增长,各类交通流量不断增加,导致交通拥堵、交通秩序混乱、交通事故增多、环境污染等问题也日趋严重。智能交通系统(Intelligent Transportation System,ITS)是当前解决上述交通问题最有效的办法。新疆个别城市根据自身交通管理需求建立了先进的交通管理系统(Advanced Traffic Management System,ATMS)。然而新疆各地区在ITS中处于基础的地位的ATMS平台的功能局限在交通监管和调度层面上,不能同时兼顾城市道路交通宏观和微观两方面的实时监控和管理。因此,将道路微型实景模型引入到ATMS中,与计算机大屏幕构成能同时监控城市道路路网中宏观和微观交通状态的ATMS平台具有较大的实际研究意义和价值。本研究中ATMS平台以克拉玛依市交通管理系统为研究背景,结合克拉玛依市区交通特性,归纳出了ATMS的主要用户及其对交通信息的具体需求。通过具体分析,构建依托于道路微型实景模型的ATMS逻辑框架和物理框架。研究设计建造道路微型实景模型作为路网宏观交通流模拟载体,其由物理支撑框架、底图层、线路层、透明板层以及景观设施层5个部分组成,主要有直观展现市区路网交通设施现状、提供当前市区路网交通流拥挤情况、信号控制系统工作状态、路灯控制情况、日常出行相关重要交通信息等功能。用STC12C5A60S2作为MCU开发电路板,设计交通状态控制器、VMS从机和信号机从机以满足交通流动态模拟的需要。研究开发平交口信息显示软件作为路网节点交通信息的显示窗口,包括UI和数据库,其中,UI采用DELPHI开发,数据库采用Paradox开发,用于存储平交口的各类信息。另外设计数据交换器作为平交口信息显示软件和道路微型实景模型上的各个平交口交通状态控制器间的数据中转站,并对通讯代码进行详细定义。
[Abstract]:With the rapid growth of traffic demand in various regions of Xinjiang, traffic congestion, chaos of traffic order, increase of traffic accidents and environmental pollution are becoming more and more serious. Intelligent Transportation system (Intelligent Transportation System,ITS) is the most effective way to solve these traffic problems. Several cities in Xinjiang have established an advanced traffic management system (Advanced Traffic Management System,ATMS) according to their own traffic management needs. However, the function of the ATMS platform, which is the foundation of ITS in Xinjiang, is limited to traffic supervision and scheduling, and can not simultaneously take into account the real-time monitoring and management of urban road traffic in both macro and micro aspects. Therefore, it is of great practical significance and value to introduce the road micro real scene model into ATMS, and to construct a ATMS platform which can monitor the macro and micro traffic state of urban road network simultaneously with the large computer screen. In this study, the ATMS platform based on the Karamay traffic management system as the research background, combined with the Karamay urban traffic characteristics, summed up the main users of ATMS and their specific needs for traffic information. Through the concrete analysis, the ATMS logic framework and physical framework based on the road micro real scene model are constructed. This paper studies the design and construction of the road micro scene model as the simulation carrier of the macroscopic traffic flow of the road network, which consists of five parts: the physical supporting frame, the bottom map layer, the line layer, the transparent plate layer and the landscape facility layer. It mainly shows the current situation of urban road network traffic facilities, provides the current urban road network traffic congestion situation, signal control system working state, street light control situation, daily travel related important traffic information and other functions. Using STC12C5A60S2 as MCU to develop circuit board, design traffic state controller, VMS slave and signal slave to meet the need of traffic flow simulation. This paper studies and develops the display software of horizontal intersection information as the display window of road network node traffic information, including UI and database. Among them, UI is developed by DELPHI and database is developed by Paradox, which is used to store all kinds of information of flat intersection. In addition, the data exchanger is designed as the data transfer station between the information display software of the flat intersection port and the traffic state controller on the road miniature real scene model, and the communication code is defined in detail.
