Mapping bicycling exposure and safety risk using Strava Metro

Mapping cycling patterns and trends using Strava Metro data in the city of Johannesburg, South Africa

Plans for smart mobility through cycling are often hampered by lack of information on cycling patterns and trends, particularly in cities of the developing world such as Johannesburg. Similarly, traditional methods of data collection such as bicycle counts are often expensive, cover a limited spatial extent and not up-to-date. Consequently, the dataset presented in this paper illustrates the sp...

Sidewalk Bicycling Safety Issues

Bicycle route and safety datasets for 2963 commuter cyclists in Ottawa and Toronto, Canada containing cyclist characteristics, collision and fall history, and regular commute route, are used for this analysis. Previous analyses found sidewalk collisions, fall and injury rates significantly higher on sidewalks versus roads or paths. Of the 52 events reported on sidewalks none were reported to po...

A probabilistic approach for safety risk analysis in metro construction

Identification and Analysis of Metro Foundation Construction Safety Risk Based on Fault Tree Analysis

Fuzzy theory and Bayesian network theory were based on the fault tree. The fault tree analysis method improved the fault analysis to obtain number of event's exact problem. Considering the characteristics of the fuzzy risk analysis at the same time, it also solved the problem of scale fault analysis modeling. The theory is applied to the cost of construction shield tunnel risk analysis, floatin...

Utilizing Crowdsourced Data for Studies of Cycling and Air Pollution Exposure: A Case Study Using Strava Data

With the development of information and communications technology, user-generated content and crowdsourced data are playing a large role in studies of transport and public health. Recently, Strava, a popular website and mobile app dedicated to tracking athletic activity (cycling and running), began offering a data service called Strava Metro, designed to help transportation researchers and urba...
