摘要：	The project 'Data Analysis for Local Roadway Assessment' conducted systematic road-safety assessment and identified major risks that can be eliminated or reduced by practical road-improvement measures. Specifically, the primary task of this project was to collect and code detailed data on key roadway and traffic control characteristics for 100-meter roadway segments from Internet-based photos on Google Street View®. From November 1, 2013, to April 30, 2014, data on more than 50 key safety-related design characteristics were carefully collected and documented for 1,566 100-meter road segments in Boone County, 3,941 in Champaign County, and 2,545 in Vermilion County. Data were collected at an average rate of 4.16 kilometers per hour. This report summarizes the main activities (training, data coding, and communication), management and control (internal and external supervision), and key results of this project.
