Summary: | 碩士 === 國立臺灣大學 === 土木工程學研究所 === 93 === The supply of transportation is the essential element for enhancing economy. As the growth of economy, the more travel demanded, the more energy needed. The problem of conventional transportation planning process, that is, starting from travel demand forecasting process, which based on socio-economic activity, and then to create the transportation building alternatives to enhance the transportation efficiency. Resulting from this procedure, more socio-economic activities require more energy consumption consequently. The public and government are facing the
dilemma of growing the economy or protecting the nature.
As the result of actual traffic flow and road condition, the fuel efficiency surveyed laboratory field is consequently unequal to the efficiency operated on the actual roads. This research combines each kind of conditions of transportation
planning and the energy consumption, which established.
In this paper, a new thinking way to revise the planning procedure is presented. A model, called energy efficiency oriented transportation planning is proposed. It is based on a reversed planning structure concept. Applying the model, various transportation system supply structures under the constraint of energy consumption
can be investigated.
It can be applied to check the possibility of serving more travel demand and to satisfy similar socio-economic activity, but consuming the same energy amount, especially when the travelers use more energy efficiency transportation modes, such as public transport, or the energy efficiency of each mode is enhanced. Under some energy consumption policy or energy saving goals, this model can build a system and estimate its level of service by applying transportation planning to check whether its supply can meet the demand, the demand derived from economy
development.
The model can illustrate the possible way of transportation supply to match with the demand that derived from socio-economic activities in certain energy conservation policy. It also can be taken as a tool to investigate the potential way and check the policy execute, whether it had made it. In brief the initial idea provokes a new concept that revises the transportation planning procedure to start
from the energy concern and then to fulfill travel demand.
