Since 2017 the Wuhan Transportation Development Strategy Research Institute has been producing and publishing reports on bicycle mobility using data from the city's Mobike bicycle share service, and CityPhi for data analysis and dynamic display of the mobility data. Using data through March 2020, the recently published "Epidemic Riding Report" illustrates changes in bike mobility during the quarantine period.
After the City of Wuhan instituted quarantine measures on January 23, buses, subways and taxis were suspended and motor vehicle use was restricted. Many of the frontline medical workers turned to bicycles, including those from the Mobike service to maintain their posts. Volunteers who provided essential services also used the bikes, as did the general public to replenish groceries and supplies during their allotted pre-scheduled shopping trip times.
The bike share played a key role for medical workers and volunteers to access hospitals. The following image compares spatial distribution heatmaps of Mobike start and end points from an average working day in 2019 (right) to a cumulative distribution from January 24 to March 12, 2020 (left) during the quarantine period. The blue locations indicate hospitals and medical facilities around which the bicycle activity is heavily concentrated, with other areas reduced as compared to a normal work day.
The same trend is seen when displaying Mobike origin-destination lines between pickup and return. The normal work day (right) reveals a pattern with multiple clusters throughout the city, but use during the quarantine (left) was mainly concentrated on access to medical facilities and hospitals.
Bike traffic data reveals hospital-related cycling routes.
The top 50 locations of hospital-related cycling accounted for 41.5% of active vehicle use during the period from January 24 to March 12, 2020.
It is expected that after the epidemic the bicycle road network in Wuhan will be upgraded systematically, and shared bicycles will be respected and protected towards the city's goals of long-term green, healthy and sustainable development.
