Trip-making and accessibility: New tools, better decisions (SSTI, 2016)

Madison access pic

Transportation researchers and practitioners have long sought other tools to complement or perhaps replace conventional methods—tools that would better analyze trips rather than speed at points in the system, speak to non-auto modes of travel, address land use solutions as well as highway infrastructure, and so on. Fortunately, new sources of data and emerging methods, as well as new-found interest in performance and scenario planning, are yielding the types of tools that the field needs. Read More >

Effects of Parking Provision on Automobile Use in Cities: Inferring Causality (McCahill, Garrick, Atkinson-Palombo and Polinski, 2015)

parking3

Automobile use has been on the rise in cities for nearly a century and so has the supply of parking. Because driving often seems unavoidable, policymakers, developers and the public push endlessly for more parking to meet demand. That push, however, might only be making matters worse. SSTI Senior Associate Chris McCahill’s research suggests that abundant parking in cities causes people to drive more, shedding important light on the question of cause and effect. Read More >

Trip-making data, TDM, and connectivity in Northern Virginia (SSTI and Michael Baker International, 2016)

Commercially available GPS data offers valuable new insight about trip origins, destinations, and routes, including short trips that travel demand models often cannot capture. Using this data, SSTI worked with Michael Baker International, the Virginia DOT, and local stakeholders to identify opportunities for managing travel demand and improving connectivity throughout Northern Virginia. This final report describes the full data set and 17 selected case studies, along with recommended projects and policies, estimated costs, and benefits for each. More Resources...

Crash fatalities climbing faster than VMT

Recent data indicate that the total number of traffic deaths in the U.S. in 2016 will be significantly higher than in 2015. The growth in fatalities represents an increasing death rate relative to population and miles traveled. The most striking increase occurred in the South Gulf region. Pedestrian and bicyclist deaths have been increasing even more rapidly. Untangling the causes behind the increasing number of road deaths overall, as well as bicycle and pedestrian deaths specifically, is difficult. Whatever the cause, traffic safety, particularly for vulnerable road users, is an increasingly pressing issue. Read More >

September webinar: A guide for complete transportation—Arizona DOT’s new design guide

In case you missed our September webinar: In February, Arizona DOT published its much-anticipated Complete Transportation Guidebook, which ADOT views as a conversation about integrating sustainable transportation practices into the planning, scoping, and design of the project development process. The guide seeks to incorporate multiple transportation modes and is meant to be accessible to government agencies at all levels that work on transportation projects. By providing guidance on available infrastructure choices with a complete transportation approach that covers the planning, scoping, and design of transportation improvement projects, ADOT is hoping to instill sustainability practices both inside and outside the agency. A recording is available on our website. Read More >

California’s new fee on hazardous railroad shipments being challenged by railroads

California’s new fee on rail deliveries of certain hazardous chemicals, including crude oil, is being challenged in federal court. The new state regulation, set to take effect this year, requires railroad companies to collect a $45 fee from their customers for each rail car carrying any one of 25 hazardous materials into the state. The funds are to help the state pay for improvements to its emergency response capabilities so it can better respond to spills resulting from train derailments. Read More >

Building the infrastructure for zero emissions and alternative fuel vehicles

A variety of electric and alternative fuel vehicles are increasingly available to consumers, which should be good news for efforts to reduce greenhouse gas emissions. However, adoption of these new, cleaner technologies is hampered by inadequate infrastructure needed to support fueling of these vehicles. Recognizing this challenge, the FAST Act directs the Secretary of Transportation to designate alternative fueling corridors for EV and alternative fuel vehicles. Read More >

Study: One-way car-sharing reduces VMT, GHG emissions, and vehicle ownership

A recent study done by researchers at University of California-Berkeley has answered several questions many have had since car-sharing began by showing that car2go members in five North American cities reduced both their annual vehicle miles traveled and also their greenhouse gas emissions. Members also sold or delayed purchasing vehicles, resulting in each car-sharing vehicle removing seven to 11 private vehicles from the road. Read More >
