Street appeal: The value of street improvements

The planning for and design of streets around the world have been undergoing a radical change via a move from a network efficiency model to a movement and place-based one. This is a fundamental change, and it is important to understand both the benefits and drawbacks that result. This research represents an attempt to capture and understand these impacts and to address the question, what is the ‘value’, in the widest sense of the word, of place-based improvements in street design. The key features of the approach adopted here were, the use of pairwise comparisons of five improved and five unimproved streets across London, a holistic analytical framework to represent the complexity of urban streets, and the use of diverse qualitative and quantitative data to understand the diverse forms of value that might accrue from interventions. As well as important methodological innovations and insights, the research revealed that in relation to street improvements in the sorts of mixed local high street locations investigated, investments in the quality of the street environment return substantial value to the everyday users of streets, and to the occupiers of space (to business) and investors in surrounding property in multiple ways.
