ance system planning key technology research, which for a large population of large cities have a more positive farreaching significance. I have to report the contents of the 20042005 issue of Beijing39。本文從停車誘導(dǎo)系統(tǒng)總體規(guī)劃設(shè)計(jì)的角度,結(jié)合智能交通系統(tǒng),討論建立了出行前子系統(tǒng)的框架結(jié)構(gòu),提供了利用互聯(lián)網(wǎng)、通信技術(shù)和媒體等不同渠道分別傳輸發(fā)布出行前停車信息的具體功能設(shè)計(jì)。結(jié)合現(xiàn)代化高科技發(fā)展所引導(dǎo)的未來演變趨勢(shì),采用Internet、通信和媒體3種傳輸渠道,構(gòu)建出行前子系統(tǒng)框架如圖1所示。按照通信技術(shù)的特性,分為無線通信和有線通信兩種傳輸方式。它還可以利用ITS的各種技術(shù)和手段,實(shí)現(xiàn)停車場(chǎng)的現(xiàn)代化管理,動(dòng)態(tài)地為出行者提供指定區(qū)域附近地停車場(chǎng)泊位/類型和停車費(fèi)用等信息,為駕駛員選擇合適地停車場(chǎng)提供決策依據(jù)?! 〕鞘型\噲?chǎng)的專用有效停車泊位數(shù)據(jù)庫的建立應(yīng)體現(xiàn)以下的三條原則: ?。?)數(shù)據(jù)庫的建立應(yīng)盡量體現(xiàn)城市中的所有停車場(chǎng)的有效停車泊位數(shù)據(jù)的歷史數(shù)據(jù)。現(xiàn)代化城市的交通離不開停車設(shè)施的建設(shè),而停車難又一直是世界各國所共同困擾的難題。因此,如何合理地解決好停車問題,已經(jīng)迫在眉睫。比如車牌號(hào)碼的記錄采用智能IC卡技術(shù),即省去了手工輸入車牌號(hào)碼的工作以及可能出現(xiàn)的手工輸入錯(cuò)誤,并增加進(jìn)出停車場(chǎng)操作的管理工作效率。其中產(chǎn)業(yè)化政策、收費(fèi)價(jià)格、信息化系統(tǒng)及管理的體制和機(jī)制是由我承擔(dān)的,大家可能也知道產(chǎn)業(yè)化政策、收費(fèi)價(jià)格二者是相互影響的,所以在講產(chǎn)業(yè)化政策的時(shí)候收費(fèi)價(jià)格也會(huì)提到一些?! ⊥恋爻杀咎?。經(jīng)過測(cè)算停車設(shè)施最大的費(fèi)用還是土地的價(jià)格,政府要合理的控制好土地的價(jià)格,才可以吸引企業(yè)來投資。本文提出的為改善交通環(huán)境而建立智能停車誘導(dǎo)系統(tǒng),以及進(jìn)行智能停車誘導(dǎo)系統(tǒng)規(guī)劃關(guān)鍵技術(shù)研究,這對(duì)于人口眾多的我國大城市具有更加積極深遠(yuǎn)的意義。 3 本系統(tǒng)適用于小型的停車場(chǎng)管理使用,即使只有一個(gè)管理人員也可以很方便的使用計(jì)算機(jī)來進(jìn)行停車場(chǎng)的管理工作。工業(yè)化對(duì)城市交通的影響、經(jīng)濟(jì)的迅速發(fā)展、城市(非)機(jī)動(dòng)車保有量的猛增、特別是大量私有汽車的出現(xiàn),使得包括中國在內(nèi)的很多國家的大城市的停車問題日趨嚴(yán)重。本文給出了基于歷史數(shù)據(jù)的和實(shí)時(shí)數(shù)據(jù)的兩種神經(jīng)網(wǎng)絡(luò)方法用于預(yù)測(cè),實(shí)踐證明,預(yù)測(cè)效果良好。2 有效停車泊位的含義 智能化的停車誘導(dǎo)系統(tǒng)中的有效停車泊位,是指正在開放的公共停車場(chǎng)內(nèi)未被車輛或者其他物品占用,可以用來停放車輛的停車泊位。 【正文】1 引言眾所周知,城市化進(jìn)程的加快帶來了城市人口的激增,進(jìn)口汽車關(guān)稅大幅下調(diào)以及我國汽車制造業(yè)的大發(fā)展必然帶動(dòng)汽車保有量的逐年增加,停車設(shè)施規(guī)劃滯后,管理混亂,建設(shè)受到用地緊張、資金短缺的制約,造成目前很多大中城市停車供需矛盾突出,停車問題已成為嚴(yán)重的城市交通問題。 通信傳輸停車信息 除了直接利用Internet外,現(xiàn)代化的通信手段也為停車信息提供了理想的傳輸途徑。由此,有必要對(duì)城市停車準(zhǔn)備出行前誘導(dǎo)信息系統(tǒng)進(jìn)行簡(jiǎn)單的簡(jiǎn)介。 5, financial subsidies, the use of injection of funds, to promote the development of public welfare. 顯示對(duì)應(yīng)的拉丁字符的拼音字典 查看字典詳細(xì)內(nèi)容169。s growing parking problem in big cities. Motorists to travel at the same time enjoy the freedom, they had to face due to lack of resources caused by the search for parking spaces in distress. Especially for the driving experience is short, travel, or are not familiar with a limited number of motorists who travel destination, if the destination before the trip did not understand the distribution of parking facilities nearby, it may be confused and convoluted, Park Patrol embarrassment. On the other hand, some car parks are set up in the ground, position a bit more, park paths far, newly built and other factors were not concerned about or even unknown, even in peak times, no one cares. Thus, it is necessary to prepare before the trip of Parking Guidance and Information System for simple profile. Prepare Pretrip parking information transmission system In order to meet the wishes of characteristics of drivers, taking into account the economic levels of different classes of drivers, knowledge, skills and information needs of the situation before the trip difference to modern hightech tools and traditional methods bined strengths to build multilevel useroriented and prehensive realtime parking information services the city before the trip information transmission system. Combined with modern hightech development trend of the future evolution of the guide, the use of Internet, munications and media transmission channels 3, subframe building before the trip shown in Figure 朗顯示對(duì)應(yīng)的拉丁字符的拼字典 查看字典詳細(xì)內(nèi)容It should be noted that the implementation of the scheme before the trip the main subsystem is twoway transmission, the subsystem can either finishing the traditional function of the passive receiving parking information, while the control center to pass the initiative to send the data, reflecting realtime parking information, and the city the ideal individual will of the user interface. Prepare the subsystem functional design before the trip To facilitate data exchange at all levels, PGIS and travel into the city before the subcentral control center, area control center, user 3 levels. The following were discussed by Internet, munications, media in the preparation of these 3 ways to stop transmission of information before the trip function design and implementation of conditions. Internet transmission query Parking Information Is actually the second generation of traveler information system of the ATIS, already has assisted in the trip before the trip and travel on the way decisionmaking functions. Is not difficult to conclude that before the trip as a subbranch PGIS to Internetbased, relying on the working platform embedded GIS, called subsystem management with electronic maps of the city39。s growing parking problem in big cities. From the parking guidance system of the angle of the overall planning and design, bined with intelligent transportation systems, discuss the establishment of a subframe structure before the trip, providing use of the Internet, munications and media, travel different channels were released before the transfer of specific functional design of parking information . Keywords: parking。s growing parking problem in big cities. From the parking guidance system of the angle of the overall planning and
