The paper describes the development and application of a new approach to planning and designing urban streets, based on their ôLinkö and ôPlaceö functions, which include transport performance, economy and environmental indicators. As a Link, a street is for movement and designed for users to pass through as quickly and conveniently as possible, in order to minimise travel time; while as a Place, the street is a destination in its own right, where people are encouraged to spend time taking part in activities. Both functions have their own sets of design requirements. This approach has led to the development of new ways of: 1. Classifying all urban streets, using a two-dimensional Link/Place matrix; 2. Measuring street performance and identifying aspects that are underperforming; 3. Prioritising areas for improvement; 4. Comprehensively assessing design area requirements; 5. Developing design options; 6. Appraising design options. The approach has been applied in several English cities, in a wide range of applications, from assessing the performance of LondonÆs strategic road network, and engaging stakeholders in the redesign of busy shopping streets, to specifying maintenance requirements in an area-wide private finance initiative highway contract.
