Plan level tools

The Plan level tool is the tool provided in the project VITRUV to support the second of three stages distinguished in the process of urban planning.

Three planning stages

The three planning stages in urban development

Departing from a concrete goal or problem, the first step in finding a fitting solution in the urban space is to investigate possible solution directions, utilising the Concept level tools.

The plan level involves the urban planner formulating, with an additional layer of examination, possible solutions to the problem or challenge at hand. These possible solutions are analysed in the context of relevant characteristics and a screening or feasibility assessment for each may be conducted. Arising from the results of this assessment, possible solutions are discounted, compared and ‘weighed up’, and the most appropriate option available (or combination thereof) is selected (which should, ultimately, accord with the proper planning and sustainable development of the city). The Plan level tools developed within the project VITRUV will support the urban planner in ensuring a holistic approach to his/her duties, by informing from him/her of the security (and connected safety) aspects.

After selecting one (or more) solutions, this is worked out and refined in the detail level, where the Detail level tool from the project VITRUV will assist.

Goal of the plan level tool

The goal of the plan level tool is to provide a susceptibility analysis for urban objects during the planning stage. It facilitates measures for probability of events and the extent of loss associated with an event being realised. It is an easy-to-use, fast-running computer tool consisting of a Window application for Windows and MAC operating systems. The goal of the plan level tool is to focus on crime and terrorism, with natural disasters a potential 'add-on' in future versions.
