Influence of weather on bus ridership

It's going to be another warm week here in Berkeley, as the Summer unofficially begins. A new article, "The influence of weather on local geographical patterns of bus usage" by Sui Taoa, Jonathan Corcoranb, Mark Hickmana, and Robert Stimsonc, in the Journal of Transport Georgraphy that looks at how weather patterns affect bus ridership. 

This paper broadens the research on weather and public transport usage by considering the micro dynamics of the effect that various weather conditions impose on micro geographic patterns of bus ridership in Brisbane, Australia. A smart card data set and detailed measurements of weather, allied with a suite of statistical and visual analytic techniques, are employed to capture the effect of weather on the local variations of bus ridership. While changes in weather conditions do not significantly affect bus ridership at the system level, some marked influence was found for rainfall, wind speed and relative humidity at a sub-system level. In addition, discernible variations of both the magnitude and direction of weather's effect were found at the sub-system level. Developing a more geographically detailed understanding of the effect of weather on public transport services serves as a critical first step towards establishing a more weather-resilient public transport system. This new understanding has the potential to contribute to an evidence base that can be used to proactively adjust public transport services in response to changes in weather conditions across different parts of the network. Further research is needed to assess how transferable our findings are to other public transport and climatic contexts.

We'll be closed Friday May 27 through Monday May 30th in observance of Memorial Day. We will resume our normal hours on Tuesday, May 31. 

Memorial Day kicks off the United States' summer travel season, which means more traffic. Much has been written about the correlation of highway crashes and holiday weekends. There's been some recent work on how to forecast holiday travel with seasonal traffic models. Other researchers have explored how integrated multimodal travel information services might help alleviate holiday traffic patterns

Whatever your plans are this weekend, have a nice one!

Uber and Lyft Leave Austin After Voters Reject Less Regulations on Ride-Hailing Apps.

This weekend Austin voters went to the polls vote on Prop 1, which if passed would have eased the regulation on finger prints and background checks for rideshare drivers in the city. The proposition failed, only garnering 44% of the Yes vote. Uber and Lyft spent $8million campaigning for Prop 1, but that may have left a bad impression on voters. If Prop 1 failed, both Uber and Lyft said they would leave Austin in a kind prisoners dilemma. True to their word, on Monday both companies announced they were halting service in the city. 

What does this mean for ride-sharing? Will more cities push for more fingerprinting and background checks for ridesharing drivers in the name of public safety? Does fingerprinting actually make riders safer

Research in this area suggests that rideshare companies don't need more safety regulation than taxis, but that they fit awkwardly into the existing regulatory framework.  Though how different is ridesharing to taxis? And can the industry be regulated to benefit consumers and drivers? Time will tell.
