A Micro-Scale Analysis of Cycling Demand, Safety and Network Quality

The 2008 California Complete Street Act delivered a mandate to carry out long range planning for cycling, walking and transit, in addition to vehicular-oriented systems, when any local government embarks on a general plan update. Two major challenges exist for implementing this mandate, including a lack of consistently collected bicycle and pedestrian data, and importantly, a lack of standardized metrics and planning tools for assessing infrastructure needs related to walking and cycling. The proposed research builds from recent advances in the San Diego region in the arena of both active travel data collection and long-range planning methods. Specifically, this project seeks to define relationships between cycling demand, bicycle network indices, network quality and safety. The project draws upon rich cycling count data collected between 2012 and 2017 in San Diego County from automated counters, as well as from about 400 short duration manual counts conducted during the same period.
