Use of Crowdsource Passive Data to Evaluate Effectiveness of Access Management Projects Proof of Concept

Implementation of access management projects has historically caused conflict between practitioners who support the safety and mobility benefits of access management and business/property owners who are concerned about the potential negative impacts of reduced access to adjacent properties. Elected officials who are responsible for supporting or approving project funding find themselves in a delicate balancing act in the debate between safety, economy, and mobility. Past evaluations of access management projects have been limited to manual traffic data collection, simulations, and evaluation of crash data many years after the project is implemented. In addition, evaluation of sales tax receipts before and after implementation of the project has been limited. The purpose of this project is to test the use of innovative data sources (Wejo connected vehicle data and SafeGraph point of interest data) to evaluate the safety, mobility, and economic effects of access management projects by comparing trips into adjacent development before and after implementation of the project. Wejo connected vehicle data is a rich data source that provides information about vehicle movements and vehicle events (e.g., hard braking, acceleration, etc.), so there are several aspects of this data that are beneficial to this evaluation. In addition, an economic analysis will be performed to evaluate the financial impacts on adjacent businesses.
