【摘要】：隨著新疆各地區(qū)交通需求迅速增長(zhǎng),各類交通流量不斷增加,導(dǎo)致交通擁堵、交通秩序混亂、交通事故增多、環(huán)境污染等問題也日趨嚴(yán)重。智能交通系統(tǒng)(Intelligent Transportation System,ITS)是當(dāng)前解決上述交通問題最有效的辦法。新疆個(gè)別城市根據(jù)自身交通管理需求建立了先進(jìn)的交通管理系統(tǒng)(Advanced Traffic Management System,ATMS)。然而新疆各地區(qū)在ITS中處于基礎(chǔ)的地位的ATMS平臺(tái)的功能局限在交通監(jiān)管和調(diào)度層面上,不能同時(shí)兼顧城市道路交通宏觀和微觀兩方面的實(shí)時(shí)監(jiān)控和管理。因此,將道路微型實(shí)景模型引入到ATMS中,與計(jì)算機(jī)大屏幕構(gòu)成能同時(shí)監(jiān)控城市道路路網(wǎng)中宏觀和微觀交通狀態(tài)的ATMS平臺(tái)具有較大的實(shí)際研究意義和價(jià)值。本研究中ATMS平臺(tái)以克拉瑪依市交通管理系統(tǒng)為研究背景,結(jié)合克拉瑪依市區(qū)交通特性,歸納出了ATMS的主要用戶及其對(duì)交通信息的具體需求。通過具體分析,構(gòu)建依托于道路微型實(shí)景模型的ATMS邏輯框架和物理框架。研究設(shè)計(jì)建造道路微型實(shí)景模型作為路網(wǎng)宏觀交通流模擬載體,其由物理支撐框架、底圖層、線路層、透明板層以及景觀設(shè)施層5個(gè)部分組成,主要有直觀展現(xiàn)市區(qū)路網(wǎng)交通設(shè)施現(xiàn)狀、提供當(dāng)前市區(qū)路網(wǎng)交通流擁擠情況、信號(hào)控制系統(tǒng)工作狀態(tài)、路燈控制情況、日常出行相關(guān)重要交通信息等功能。用STC12C5A60S2作為MCU開發(fā)電路板,設(shè)計(jì)交通狀態(tài)控制器、VMS從機(jī)和信號(hào)機(jī)從機(jī)以滿足交通流動(dòng)態(tài)模擬的需要。研究開發(fā)平交口信息顯示軟件作為路網(wǎng)節(jié)點(diǎn)交通信息的顯示窗口,包括UI和數(shù)據(jù)庫(kù),其中,UI采用DELPHI開發(fā),數(shù)據(jù)庫(kù)采用Paradox開發(fā),用于存儲(chǔ)平交口的各類信息。另外設(shè)計(jì)數(shù)據(jù)交換器作為平交口信息顯示軟件和道路微型實(shí)景模型上的各個(gè)平交口交通狀態(tài)控制器間的數(shù)據(jù)中轉(zhuǎn)站,并對(duì)通訊代碼進(jìn)行詳細(xì)定義。
[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.
