[snipped from the Executive Summary:]
This research, conducted between 2005 and 2009, aimed to investigate whether the implementation of new pedestrian facilities (or the improvement of existing facilities) led to increased pedestrian rates, and to record these changes in a standardised format that could be used in transport planning and project funding. This study also tried to develop an expected pedestrian-usage model, based on before and after data analysis, for planners and funding agents to use when planning new or improved facilities and evaluating projects. The final part of the project involved developing a monitoring database containing before and after pedestrian count data for various new and improved pedestrian facilities, along with a list of accompanying factors such as safety, delay and directness.
Results from the before and after pedestrian count surveys and analysis of the individual case studies showed that the implementation of improved pedestrian facilities resulted in increased usage at seven out of the eight sites analysed. The magnitude of these changes varied between sites, from 7% for the Moorhouse Ave signalised pedestrian crossing to 90% for the kerb extensions at Collingwood St. The reasons for the increases in flows were analysed in each of the individual case studies, and were found to be a mix of factors such as safety, delay and directness. Overall, it was observed that the construction of kerb extensions/refuge islands resulted in the largest increase in pedestrian numbers, followed by the installation of kea crossings.
