Cycle Zone Analysis: An Innovative Approach to Bicycle Planning

Cycle Zone Analysis is a new metric that can help planners and decision makers assess existing conditions and future potential for bicycling and develop strategies to maximize returns on financial investment through increases in mode share. This Geographic Information System (GIS) based analysis considers many factors known to influence bicycling activity, including: land use mix, roadway density and connectivity, bike way quantity and quality, topography, employment and population density. This analysis is similar to the traditional Transportation Analysis Zone (TAZ) based systems used for motor vehicle modeling currently performed at the local, regional and state levels. A second new analysis metric, the Bikeway Quality Index (BQI) is used to measure the quality of on-street bicycle facilities. The methodology allows evaluation of features unique to various types of bike ways (e.g. bike lane width and traffic calming along shared streets). Portland, OR planners used this tool to: better understand the impact of several individual factors on cycling potential in various parts of the city, create a composite picture of existing cycling quality, evaluate future potential for cycling and verify that increased cycling appears to roughly match quality ratings in each cycle zone. This tool was originally developed in a partnership between the Portland Bureau of Transportation and Alta Planning and Design for use in the update of Portland’s Platinum Bicycle Master Plan. Further applications of this tool in areas such as Greater Vancouver British Columbia will allow enhanced calibration and validation of this model as a predictor of cycling potential.
