Abstract

PROJECT IDEA: Urban roads are under great pressure due to the need to accommodate increased mobility levels and 'just in time' deliveries and servicing, at the same time that governments are putting increased focus on developing attractive spaces to support active modes of transport and encouraging place activities, all within fixed road widths. However, decisions to reallocate roadspace are usually made on an ad-hoc political basis. In particular, the option generation stage tends to be omitted. PURPOSE AND OBJECTIVES: We developed two web-based tools for generating options for reallocating roadspace. The tools assist planners to explore feasible solutions that consider the needs of all road uses (both movement and 'place') and a range of economic, social, and environmental objectives. FINDINGS AND ORIGINALITY: The Policy Interventions tool generates options for the static or time-based reallocation of roadspace, selected from a library of 210 types of interventions. It shows information on design, suitable context, examples, and empirical evidence on effects. The Road Designs tool generates detailed roadspace allocation designs, in cross section, combining different design elements. The tools were created with input from road user groups representing pedestrians, cyclists, and public transport users. Five European cities (London, Lisbon, Budapest, Malmo, and Constanta) applied the tools to generate options for the redesign of busy roads, and evaluated the tools, providing feedback that was used to refine the tools. CONCLUSION AND POLICY IMPLICATIONS: The developed approach improves the process of roadspace allocation, as it generates a wider range of options than what are usually considered, providing solutions that reduce possible conflicts among different users, by making better use of space and time. The tools were validated by its use in real-world scenarios in the five cities and are now available for wider use in other cities.
