Summer is upon us so the library will be closed next week, June 13-17, for a quick vacation. We will resume with normal library hours on June 20th. See you then!

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.

ITS Library Closed 5/27-5/30 for Memorial Day

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. 

Bay Area Bike Share Rolling Into The East Bay

Bay Area Bike Share is expanding with new stations in San Francisco and San Jose, but also its first deployment in the East Bay with 34 stations. The Phase 1 expansion sites are clustered around the UC Berkeley campus and down Telegraph towards 12th Street BART. What impact will these new stations have on mode choice in the East Bay? In the last 5 years bikeshare systems in the U.S. have greatly matured, and have come a long way from early implementations.  The current literature is very robust. 

Alaska Airlines buys Virgin America

After some brief speculation, it was announced this morning that Alaskan Airlines' parent organization bought Virgin America for $2.6 billion in cash. This acquisition will bolster Alaskan's presence on the West Coast and particularly in California. Virgin's chairman Richard Branson wrote about the brand's history and his thoughts on the future

It's expected this deal won't experience regulatory hurdles that faced the American Airlines and US Airways deal because their market shares are much less. Given the geographic idiosyncrasies of airline mergers, it will be interesting to see how this deal plays out. What will be the implication for consumers? Initial impressions have been kind of negative

FHWA Announces new Bicycle-Pedestrian Safety Performance Measures

Today FHWA issued a press release announcing new safety performance measures, including for the first time new measures for bicycle and pedestrian safety. The final rules will be published on FHWA's Highway Safety Improvement Program website soon, but can be found here in the Federal Register.  

SafeTREC researchers have worked with Caltrans to develop data collection systems for California to make it possible to monitor system performance for bicycles and pedestrians. This data will be critical to implementation of these new performance measures. 

Stay tuned. 

New TRB Special Report on Technology-Enabled Transportation Services

Last week TRB Special Report 319: TRB Special Report 319: Between Public and Private Mobility: Examining the Rise of Technology-Enabled Transportation Services was released. The report looks at how transportation network companies (TNCs), such as Uber or Lyft, have disrupted mobility. The report, its appendices, and a video presentation of the findings can be found here

Friday ITS Transportation Seminar! Location: A Persistent Framework

It's a new school year, and new semester, and a new series of the ITS Transportation Seminars! Kicking things off this week is Jane Macfarlane, Head of Research for HERE. She give a talk on "Location: A Persistent Framework".

Advances in the Internet of Things (IoT), Networking and Connected Car technologies are radically transforming how maps are created and used. Currently, devices are collecting and delivering location data at a scale greater than ever. Although cloud computing provides the computing scale and power required to process these data, new mapping and analytic frameworks are needed to extract useful and actionable knowledge effectively from the data produced by IoT and connected cars. This discussion will provide examples of location data and some of the analytics that HERE uses to transform this data into a higher level understanding of road network dynamics. We will also show how new types of ecosystems are being created by analytics around location data, IoT, and mobility services. Finally, we will discuss how location as a persistent framework will continue to support the very human part of mobility which is Context.

The seminar takes place today, September 4th at 4:00 PM in 290 Hearst Memorial Mining Building with a reception to follow. Cookie Hour will be at 3:30 PM in the same location.

See you this afternoon!
