Research On Characteristic And Index System Of Comprehensive Transportation Demand

This dissertation is to study comprehensive transportation demand as well as its characteristics, and to establish describing index system. It is consisted of the following parts:1. Reviewed and analyzed current research situation and result, set forth purpose and emphasis of the dissertation based on domestic practice and feature of comprehensive transportation in China.2. Analyzed limitation of traditional definition of comprehensive transportation demand, put forward a new concept and explanation, and classify comprehensive transportation demand into lag status, adapting status and preceding status based on matching degree between transportation demand and supply, and bring forward meaning and attribute for every status.3. Deeply studied on generation principle of comprehensive transportation demand by analyzing original motility, accelerating condition and restraining condition of comprehensive transportation demand, along with transform process from unrealized demand to realized demand. Apply systems analysis method to distinguish main influence factors according to direct influence degree criteria.4. Described comprehensive transportation demand characteristics from the view of general, time, space and individual attribute in detail.5. Established quantitative and qualitative index system to describe comprehensive transportation demand characteristics, which includes total 20 indices composed by general indices, time indices, space indices and individual attribute indices, and illustrate the meaning and calculation methods.6. Applied method of circle fluctuation and spectral analysis to characteristic indices calculation at case study by surveying and collecting data, apply methods of circle fluctuation and spectral analysis on characteristic indices calculation, results testify the rationality and feasibility of the index system established by the thesis.
