    Application requirements and selection procedure for urban transport planning models for developing countries
    (University of Dar es Salaam, 2007) Bwire, Hannibal
    This study develops a unified framework for a model selection process that is suitable to systematically guide the selection decision process of a transport planning model that is most appropriate for a particular planning context. It is motivated by the notion that the ability to judge and select the most appropriate model is one of the most important elements of the contemporary urban transport planning process. Transport models have become important forecasting and decision-support tools in the transport planning process, and their use is well established in developed countries. Most developing countries, however, lack such capabilities mainly due to the lack of quality data and of a sufficient framework for the model selection and application. The lack of quality data is mainly associated with the lack of systematic assessment of data sources and methods of data collection. The lack of a sufficient framework for the model selection is due to the lack of appropriate model application requirements and the lack of suitable model selection process. To provide groundwork for achieving the study objectives, existing literature is reviewed and evaluated. Gaps in strategy for assessment of methods of data collection, in conceptual framework upon which models application requirements are derived and in model assessment and selection methodologies are identified. The study fulfilled these gaps by providing improved methodologies. Application and evaluation of the methodologies on the case studies and the case study area evidences their benefits and their applicability to the urban transport planning process in developing countries.
