【正文】 transportation planning model, requiring the estimation of trip generation (how many trips for what purpose), trip distribution (destination choice, where is the traveler going), mode choice (what mode is being taken), and route assignment (which streets or routes are being used).More sophisticated forecasting can include other aspects of traveler decisions, including auto ownership, trip chaining (the decision to link individual trips together in a tour) and the choice of residential or business location (known as land use forecasting).Transportation engineering, as practiced by civil engineers, primarily involves planning, design, construction, maintenance, and operation of transportation facilities. Operations and management involve traffic engineering, so that vehicles move smoothly on the road or track. Older techniques include signs, signals, markings, and tolling. Newer technologies involve intelligent transportation systems (ITS), including advanced traveler information systems (such as variable message signs), advanced traffic control systems (such as ramp meters), and vehicle infrastructure integration. ITS (Intelligent transportation system)? ITS refers to efforts to add information and munications technology to transport infrastructure and vehicles in an effort to manage factors that typically are at odds (不一致) with each other, such as vehicles, loads, and routes to improve safety and reduce vehicle wear, transportation times, and fuel consumption. ? ITS es from the problems caused by traffic congestion(擁塞 ) and a synergy(協(xié)同增效作用 ) of new information technology for simulation, realtime control, and munications works.What is ITS?? 智慧型運(yùn)輸系統(tǒng)(ITS, Intelligent Transportation System)乃是應(yīng)用先進(jìn)的 電子、通信、資訊與感測(cè) 等技術(shù)，以整合 人、路、車 的管理策略，提供 即時(shí)(realtime)資訊以增進(jìn)運(yùn)輸系統(tǒng)的 安全、效率及舒適性 ，同時(shí)也減少交通對(duì) 環(huán)境 的衝擊。? 相關(guān)資訊傳送給用路人與相關(guān)道路管理單位，以達(dá)到運(yùn)輸效率最大化及運(yùn)輸安全之目的。^ WAN LAN信號(hào)柱無(wú)線通訊業(yè)者車輛子系統(tǒng) (OBC)聯(lián)外子系統(tǒng) (ISP)中心子系統(tǒng)DSRCDSRCWACWACWANWAN公司、家戶DesktopWAPPDA聯(lián)外子系統(tǒng)其他用路人 子系統(tǒng)智慧型公車站牌公車車載電腦定位承載率行車記錄交通資訊 接收到站訊息交通資料庫(kù)優(yōu)先號(hào)誌策略 資料融合資料交換 定位資料 WEB 伺服42APTS運(yùn)作示意簡(jiǎn)圖43目前應(yīng)用 APTS通訊系統(tǒng)之規(guī)劃u公車站牌動(dòng)態(tài)資訊顯示 u車上資訊顯示u公車定位輔助 u車隊(duì)運(yùn)作與管理 u大眾運(yùn)輸旅行安全系統(tǒng) 44先進(jìn)車輛控制及安全系統(tǒng)(Advanced Vehicle Control and Safety Systems, AVCSS)?
