| Summary: | 碩士 === 國立臺北大學 === 都市計劃研究所 === 99 === Facing the issues of climate change, global warming and energy consumption, it awakens human beings to revise and examine their lives once again. The consciousness of environmental protection and sustainability has then been raised and gradually involved in daily lives. In order to moving toward a sustainable future, the vogue of lifestyles of health and sustainability associated with the promotion of Taiwanese film, Island Etude in 2007, leads to the craze of bicycle grand tour island wide. A bicycle does no longer simply play the role as one of transportation modes, but it becomes a kind of green recreation equipment. Bicycling recreation in Taiwan has easily associated with the concepts of LOHAS and eco-friendly living styles due to the propagandas and promotions from the media. Since then bike riding has been promoted as one of good and brand new options for pastimes. Along with the rapid growth of biking in Taiwan and planning to boast the trend for biking, the government has aggressively developed and built island-wide bikeway networks. However, the current bikeway network planning practices are considered not well-organized, unable to satisfy the demand of active planning, lack of systematical and practical planning tools and dependent on planners’ professional experiences or instincts.
For these reasons, the purpose of this study is to develop a layout planning model for bikeway networks and service stations in a recreation area by using of mathematical programming approach. First of all, through the literature review, the study summarized the important elements for planning bikeway networks and defined the decision-making problem of bikeway network design. Furthermore, based on reviewing the literature, the study formed a framework to plan bikeway networks in a recreation area. Next, the research proceeded to interview different stakeholders to clarify the decision-making contents and questions, and developed the model by mathematical programming approach. The model is designed as a multi-objective 0-1 programming problem, and the ε-constraint method was applied to solve the problem to search non-dominated solutions as alternatives. Finally, the developed model was applied on the Sanzhi area in ‘North Coast & Guanyinshan National Scenic Area’. The case study collected realistic data for model parameter values and created concrete network alternatives for verifying the applicability and rationality of the developed model.
The case study resulted in four alternatives, which performed significant trade-off relationships among objective values except for the first objective. In addition, the model planning results are superior to the existing bikeways. Through scenario analyses, simultaneously adjusting the measurement of the safety parameter and the construction budget indeed changed the network and service station layouts and objective values of alternatives . This research provides bikeway planning aids in recreation areas to planners. The process of case study can be applied as a reference for model applications in other recreation areas. The planning results of case study offer concrete recommendations to the administration of ‘North Coast & Guanyinshan National Scenic Area’ for further upgrading the existing bikeways.
