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

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...

Texas DOT considers major highway removal in new plan for Dallas

Earlier this month, the Texas DOT released CityMAP, a document outlining how the agency might handle Dallas’ aging highways over the next 24 years. Most notably, it could lead to the removal of two major freeways from the downtown entirely. Read More >

Montana approves digital billboards amid continuing national debate

The Montana Transportation Commission recently voted 4-1 to allow digital billboards along highways in areas zoned commercial or industrial. However, they are subject to a number of restrictions aimed at reducing their distraction to drivers—prohibiting movement and flashing, requiring a minimum display time of eight seconds, limiting brightness, keeping them away from intersections, and setting spacing requirements between signs. While digital signs are getting the go ahead in Montana, they are facing opposition in other parts of the country. Read More >

Report summarizes Wisconsin bicycle and pedestrian crash circumstances

A report released by University of Wisconsin-Milwaukee researcher Robert Schneider looks at crashes involving pedestrians and bicyclists throughout Wisconsin from 2011-2013 to determine the conditions behind the most serious crashes, those resulting in fatalities and serious injuries. Schneider details the type of roadway, time of day, traffic controls, presence of bicycle or pedestrian facilities, and direction of travel for the parties involved. He also looked at age and gender and whether alcohol was involved. Read More >

FHWA encourages ROW solar facilities

As DOTs look to meet environmental goals and bring in revenue, several have turned to using building roofs and surplus ROW to site solar-electric generating systems. To help give practitioners a grounding in some of the issues they may encounter, FHWA has published a new online guide: Renewable Energy Generation in the Highway Right-of-Way. Read More >

Breathe easy: Sleep apnea and transportation safety

In a step towards establishing rules specific to obstructive sleep apnea—a condition that can cause daytime drowsiness and reduced reaction time—the Federal Motor Carrier Safety Administration and the Federal Rail Administration have issued an Advance Notice of Proposed Rulemaking to address the challenge of finding a balance between government’s interest in protecting public safety on highways and the industry’s workforce concerns about the ability of truckers to earn a living.
