Route management in Safer Transportation Network Planning

Safety principles, planning framework and library information


Hummel, Ton



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 ‘Route management report', the following reports have been published in this series: -Access management in Safer Transportation Network Planning (Hummel, 2001a); -Land use planning in Safer Transportation Network Planning (Hummel, 2001b); -Intersection planning in Safer Transportation Network Planning (Hummel, 2001c). The information in this report will be used to guide the structure and the programming of different parts of the Safer-TNP tool with respect to route management. 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. In this report, a method is described to persuade road users to use the safest possible routes in the network. A diagnostic tool is described to analyse the route-choice for the most important origin-destination relations in the network. If the chosen routes are not the safest (or most functional) routes in the network, techniques are described to redirect traffic by either increasing travel time on the undesired routes or by decreasing travel times on the desired routes.
