Land use planning in Safer Transportation Network Planning

This report is one in a series of publications, used in the development of the network planning tool ‘Safer Transportation Network Planning' (Safer-TNP). The publications were used to guide the development of planning structures, diagnostic tools, planning recommendations, and research information in the computer tool Safer-TNP. Safer-TNP is a design tool that guides network planners in designing safe transportation networks (or improving safety of existing transportation networks). It provides the practitioner with diagnostic tools, and guiding information. At the moment of publication of this report, Safer-TNP is still being developed. Besides this ‘Land use planning report', the following reports have been published in this series: -Access management in Safer Transportation Network Planning (Hummel, 2001a); -Route management in Safer Transportation Network Planning (Hummel, 2001b); -Intersection planning in Safer Transportation Network Planning (Hummel, 2001c). The information in this report is used to guide the structure and the programming of different parts of the Safer-TNP tool with respect to land use planning. Described is, in a step-by-step procedure, what information is needed, and in what way the information should be processed. In the last chapter of the report, background information is provided to give users of the tool guiding information. Because of the specific purpose of this report, its structure and style deviate somewhat from regular research reports. Because the different chapters are used in different stages of the development of Safer-TNP, there is some repetition of information. Furthermore, the information is written in telegraphic style, to simplify the electronic packaging of information in Safer-TNP. Land use planning may have an important influence on both mobility and traffic safety. This because the number of generated trips, the modal choice, the length of trips and the choice of route are to a large extent determined by the spatial organisation of land use. In this report, effects on road safety of the following land use decisions are discussed: -Distribution of origins and destinations -Density of land use -Urban growth patterns -Safe network shapes -Size of residential areas -Provisions for alternative modes.
