Comprehensive Safety Analysis Of Vulnerable Road User Involved Motor Vehicle Crashes, Farah Jazi Al-Mahameed

Theses and Dissertations

This dissertation explores, identifies, and evaluates a multitude of factors significantly affecting motor vehicle crashes involving pedestrians and bicyclists, commonly defined as vulnerable road users (VRUs). The methodologies are guided by the concept of safe behavior of different parties that are primary responsible for a crash, either a pedestrian, a bicyclist or a driver, pertaining to roadway design, traffic conditions, land use and built environment variables; and the findings are beneficial for recommending targeted and effective safety interventions.

The topic is motivated by the fact that human factors contribute to over ninety percent of the crashes, especially the ones involving …

Exploratory Spatial Data Analysis In Traffic Safety, Amin Azimian, Dimitra Pyrialakou

International Journal of Geospatial and Environmental Research

This paper presents an exploratory spatial data analysis (ESDA) of road traffic crashes at different severity levels in West Virginia (WV). Although ESDA can support transportation safety decision-making by helping planners understand and summarize crash data, it is underutilized in practice. This paper describes the application of five representative easy-to-use method to identify crash patterns and high crash-risk counties in WV. Analysis of crash data from 2010 to 2015 indicated that traffic crashes in WV were not spatially correlated. However, crash severities were found to be positively correlated.

Theses and Dissertations

ABSTRACT

PUBLIC TRANSIT AND MICRO-MOBILITY: IDENTIFYING THE IMPACTS OF BIKESHARE ON PUBLIC TRANSIT RIDERSHIP IN THE CITY OF CHICAGO

The variation of transit and bike share access amongst the communities in Chicago, in terms of their social, ethnic and economic segregation was investigated. The findings identify the area suitable for implementation of micro mobility as a first and last mile option. Based on transit connectivity and population mix, the communities are ranked into five groups: 1) Central: excellent transit and bike share access serving the micro mobility purpose; 2) North Side : good transit access which can be improved further …
