【正文】 , Stockholm, and London, where a congestion charge or fee is collected from vehicles entering a congested city center.Variable speed limitsVariable speed limits which change with road congestion and other factors. Typically such speed limits only change to decline during poor conditions, rather than being improved in good ones.Example variable speed limit sign in the United States.Emergency vehicle notification systems? The invehicle eCall is an emergency call generated either manually by the vehicle occupants or automatically via activation of invehicle sensors after an accident. When activated, the invehicle eCall device will establish an emergency call carrying both voice and data directly to the nearest emergency point. The minimum set of data contains information about the incident, including time, precise location, the direction the vehicle was traveling, and vehicle identification.Cooperative systems on the road? Communication cooperation on the road includes cartocar, cartoinfrastructure, and vice versa. Data available from vehicles is acquired and transmitted to a server for central fusion (結合 ) and processing. This data can be used to detect events such as rain (wiper activity) and congestion (frequent braking activities). ? The goal of cooperative systems is to use and plan munication and sensor infrastructure in order to increase road safety. 先進用路人資訊系統(tǒng)(Advanced Traveler Information Systems, ATIS)? ATIS係藉由先進資訊、通訊及其他相關技術，提供旅行者必要之資訊。大量的汽、機車排放廢氣，威脅大自然與環(huán)境的永續(xù)發(fā)展。Introduction? The planning aspects of transport engineering relate to urban planning, and involve technical forecasting decisions and political factors.? Human factors are an aspect of transport engineering, particularly concerning drivervehicle interface and user interface of road signs, signals, and markings.Technical forecasting of passenger travel usually involves an urban 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
