Transport engineering aims to ensure the safe and efficient movement of people and goods.


The planning aspects of transportation engineering relate to urban planning, and involve technical forecasting decisions and more difficult political factors. Technical forecasting or urban passenger travel presently involves what is called the four-step urban transportation planning model, requiring the estimation of trip generation (how many trips for what purpose), trip distribution (destination choice, where are you going), mode choice (what mode is being taken), and route assignment (which streets, transit routes are being used).


The design aspects of transportation engineering include the sizing of transportation facilities (how many lanes or how much capacity the facility has), determining the materials and thickness used in pavement, designing the geometry (vertical and horizontal alignment) of the roadway (or track).


Operations and management involve traffic engineering, so that vehicles move smoothly on the road or track. Older techniques include signs, signals, and markings. Newer technologies involve Intelligent Transportation Systems, including Advanced Traveler Information Systems, such as variable message signs, and Advanced Traffic Control Systems, such as ramp meters. Human factors are an important aspect of transport engineering, particularly concerning driver-vehicle interface and user interface of road signs, signals, and markings.

Transport Engineering (397 words)
Singapore's transport engineering sector comprises the aerospace, marine and offshore engineering, and land transport industries.
To ensure the continued availability of skilled manpower to support the transport engineering industries, Singapore has initiated new education, recruitment and RandD programmes, including establishing the Centre for Offshore Research and Engineering (CORE) to encourage research collaborations with industry in the area of oil and gas and offshore engineering technologies.
In addition, Singapore's highly reputable mechanical engineering capabilities have been, and continue to be, vital to the development of the transport engineering industry in ensuring high value-added manufacturing, and headquarters and distribution activities.
