Cycling is growing in Australia. The number of bike trips to work in the Greater Melbourne area has increased from 12,124 in 1991 to 25,572 in 2011. Despite the growing interest in cycling, bike safety has remained a concern.
In this project, we visualize 5 years' worth of bicycle crashes from 1/7/2008 to 1/7/2013. We used the Strava Global Heatmap as the background layer. Strava is a cycling app which allows users to track all their rides. The Global Strava Heatmap includes more than 200 billion data points from users showing where people (or more precisely Strava app users as an imperfect sample of population) ride. The number of bike crashes alone does not give a complete picture of the safety characteristics of a location. Crash rate is actually a better measure determining the relative safety considering the bicycle traffic volume. Since bicycle traffic volume data is scarcely available, we have used the Strava Heatmap to fill the gap.
The Donut chart on the right shows bicycle crash severety distribution. Also, the line chart below shows the number of crashes per month since 2008. Seasonal effects are clear.
This project is funded by the Faculty of Engineering Seed Funding and the Immersive Analytics Project at Monash University.
