In working with transportation agencies across the U.S., our team often faces questions about the role of safety in accessibility analysis. While we know the safety and comfort of streets clearly impacts access for people on foot or bicycle, the effects of accessibility on overall safety haven’t been clear. Fortunately, leading experts in both accessibility and traffic safety recently teamed up to answer this question.
A study of out-of-home participation in social and civic activities among Canadian senior drivers and non-drivers sheds light on the problems faced by both individuals and communities to keep older adults engaged and healthy. Of particular concern was the finding that non-driving seniors in rural areas and small towns had a significantly higher decline in out-of-home activities when they no longer had a driver’s license.
A trio of U.S. House members along with 10 co-sponsors have introduced a pair of bills that would set destination access as a national performance measure. Both bills describe destination access, aka “accessibility,” in terms of travel times by auto, transit, walking, and biking, with consideration for traffic-stress levels on the active modes. One of the bills focuses on access to employment, while the other focuses on access to non-work destinations such as shopping and schools.
In choosing where to live, people strive for a combination of short driving commutes and good transit access, according to a new study spanning three large regions: Atlanta, Seattle, and Detroit. Walkable neighborhoods are also a plus, depending on the region.
A new study by SSTI and the Traffic Operations and Safety Lab at UW-Madison provides a partial roadmap to the future for transit in smaller cities. The study gave Eau Claire, Wisconsin—a city nearing 70,000 people—a look into emerging transit technologies and insight on their residents’ perspectives toward transit. SSTI also laid out a dozen future scenarios, evaluating each one using accessibility metrics.
The Accessibility Observatory at the University of Minnesota recently released a one-of-a-kind report that ranks the country’s 50 largest metropolitan areas (by population) according to accessibility to jobs via bicycle. The report is a product of a multi-year study, where the researchers analyzed land use and transportation systems to measure accessibility to destinations via different modes. The researchers also incorporated traffic stress and bicycle comfort in measuring accessibility.
As in the United States, many rail transit lines in Sydney, Australia, have imperfect connections to the local street and pedestrian networks. In Sydney, 44 of 178 rail transit stations have entrances on only one side, necessitating long walks for unlucky travelers seeking to get to the hard-to-reach platform. A new report calculates the potential benefit from adding missing links between stations and local networks at those 44 stations. They calculate the increase in accessibility to the platforms from surrounding neighborhoods, then they estimate the effect in ridership from that change.
DOTs and planning agencies interested in measuring access to destinations have a growing number of packages and data sources to choose from. Folks not looking to reinvent the wheel are turning to shiny products like Citilabs’ Sugar Access, Conveyal, and Remix. But those with tighter budgets and a little more technical expertise can build on existing platforms like OpenTripPlanner, UrbanAccess, and now the Accessibility Toolbox for R and ArcGIS, featured recently in Transport Findings.
With the constant rise in obesity numbers and health concerns, planners and designers around the world are trying to bring back physical activity in day-to-day commuting behavior. Addressing health concerns through active transportation solutions not only brings us a step closer to a healthier community, but is also cost effective. Improving walking access to public transit stations is one such solution and was the theme of a paper published in the May issue of ITE journal.
Transportation agencies and metropolitan planning organizations often wrestle with how to properly value transportation investments, especially when it comes to things that can’t be measured in terms of vehicle delay, such as multimodal access and environmental justice. Some of these challenges are tackled in a new issue of Research in Transportation and Business Management, edited in part by SSTI. Those familiar with SSTI’s recent work in the development and implementation of accessibility metrics may be interested in a paper describing a new measure of non-work accessibility.
