【正文】 his document examines a wide range of these technologies, but focuses on those monly known as advanced vehicle/highway systems (AVHS) and on related technologies that affect or plement AVHS. The term AVHS refers to advanced technologies that are applied to motor vehicle transportation and traffic operations, such as technologies for: automatic vehicle identification and billing。 advanced traffic signal control and optimization。 and tune the radio to the AHAR frequency. Teletext and videotex systems, which have been used in Europe for route planning, are usually accessed from the home or office and provide travelers with written information on traffic conditions. interactive versions of such systems allow drivers to query databases for optimal path information and to receive written route instructions. Vehiclebased navigation systems automatically track vehicle location, and some, using puterized map bases, show the current location on an electronic map display of the surrounding area. When the driver enters origin and destination information, these systems can provide detailed advice on which streets to follow and when to turn. Enhanced versions of such devices that have 蘇州大學(xué)本科生畢業(yè)設(shè)計（論文） 26 munication links to the infrastructure are being developed。 and automatic vehicle spacing – both steering (lateral) and headway (longitudinal). AVHS does not include technologies used in vehicle manufacture, road construction, or mass transit system design and operations. Domestic research in most areas of AVHS was active in the 1960s, but tapered off during the 1970s as funding and interest declined. Recently, AVHS has received renewal attention in the United States for several reasons. As air pollution and traffic congestion have worsened, many see AVHS as tools for increasing road safety, reducing traffic delay and incident response time, and increasing traffic capacity. Since a large portion of congestion is caused by accidents, significant benefits can result from reducing both the number of accidents and the time it takes to clear the roadway after an accident occurs actions that do not require AVHS, but can be made easier by them. Others see AVHS as a means for reducing fuel consumption and air pollution, making mercial shipping more efficient, and easing the driving task for physically limited drivers. But perhaps the major reason for the renewed interest is the high level of attention being given AVHS by European and Japanese researchers. Europe and Japan both have highprofile 蘇州大學(xué)本科生畢業(yè)設(shè)計（論文） 25 governmentsponsored research and development programs under way which include participation by industry and academia. As . participation in these foreign programs is limited and, in some cases, prohibited – automobile manufacturers and technology experts familiar with AVHS raise concerns that the United States is falling behind in research and technology development. . manufacturers fear that they will beat a petitive disadvantage relative to foreign firms when AVHS “products” enter the motor vehicle market. Advanced Driver Information (ADI) Systems ADI systems give drivers current information on road and traffic conditions so that they can plan their routes to avoid areas of congestion. ADI systems range from oneway audio munications to interactive video munications, and some of the more advanced systems plan routes automatically after the driver has provided origin and destination information. The systems can be home, office, or vehiclebased. While they can operate independently, they are much more useful with information about the transportation infrastructure current roadway and traffic conditions. Traffic reports on mercial radio stations represent the most basic of the ADI technologies. in limited use, highway advisory radio and its variations use dedicated frequencies (usually at the ends of the broadcast spectrum) to transmit traffic information. Tested, but never implemented, automatic highway advisory radio (AHAR) can automatically do some or ail of the following: signal the driver that an advisory notice is about to be broadcast。 collision warning and avoidance。 collision warning and avoidance。只有兩者兼?zhèn)洌缆返耐ㄐ心芰υ黾?，交通堵塞減少，才能逐漸滿足多數(shù)人的需求?？梢越邮茏?，就不要開車了；實在接受不了的，能與別人搭車的，就選擇搭車的方式。 司機(jī)通過接收到的信息及時調(diào)整行車路線，因事故造成的擁堵就會減少很多 ，時間能是能大把大把的節(jié)省下來 。 由于交通工具的載體是人，所以從根源上來說，改變?nèi)说某鲂?、通行意識才是最根本的問題。這些措施是從路面部分改善交通狀況。即使是平常情況之下，車間距也不會刻意保持在 4~8m 之內(nèi)。 謝謝我的父母，沒有他們辛勤的付出也就沒有我的今天，在此將最崇高的敬 意獻(xiàn)給他們！ 本文參考了大量的文獻(xiàn)資料，在此，向各學(xué)術(shù)界的前輩們致敬！ 學(xué)業(yè)有盡而學(xué)無止盡，由衷感謝給予我?guī)椭拿總€人。設(shè)計， 2021，第 5期 [14] 馬青、丑萬錦、田芳，城市公共交通發(fā)展的政策探討，沈陽建筑工程學(xué)院學(xué)報，1999，第 15卷第 2 期 [15] 郟紅雯、盧勇，交通心理學(xué)， 2021， 2021 年 9 月第 1 版，中國人民公安大學(xué)出版社 群眾出版社， 216217 蘇州大學(xué)本科生畢業(yè)設(shè)計（論文） 18 [16]馬社強(qiáng)、劉東、路峰， 車速對交通安全的影響及管理研究，公路交通技術(shù)， 2021，第 5 期， 139142 [17]郟紅雯、盧勇，交通心理學(xué)， 2021， 2021 年 9月第 1版，中國人民公安大學(xué)出版社 群眾出版社， 160163 [18]顏桃為、馬健霄、魏永平，信號交叉口 運行狀況評價研究，山東交通學(xué)院學(xué)報，2021，第 18卷第 1 期， 2225 [19] Bo Chen/ Harry H.
