Renewable Energy in the Right of Way

massdot-solar-3-shot

At SSTI’s first Sustainability Directors Community of Practice meeting in June 2015, attendees discussed their states’ interest in siting solar and other renewable energy generation facilities in the highway right-of-way but cited uncertainty regarding FHWA rules and unfamiliarity with the business side of renewable energy production as major hurdles. In an effort to support these efforts and allow interested states to learn from others, SSTI has gathered the technical documents gathered here, under the headings below, comprise a living repository for state DOTs and others to use as examples as they develop their own ROW renewable energy projects.

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...

U.S. gets “F” for design and policy to support walking while pedestrian fatalities rise

A national coalition of prominent health organizations issued a failing grade to the country as a whole and the vast majority of states when they looked at whether community designs and policies support walking. At the same time, recently-released traffic safety data show a rising number of pedestrian fatalities at a time when driving is increasing. Read More >

Is congestion pricing equitable? Data suggests “yes” in the Portland metro region

Critics of congestion pricing sometimes raise equity as a concern. They question whether charging a higher fee during congested times of day places a disproportionate burden on lower-income individuals who may have no choice but to travel during those times. Economist Joe Cortright recently tested this claim using data from the Portland metropolitan region and found the opposite: according to Cortright, the data suggests that peak hour road pricing would primarily impact individuals with the highest incomes.

Traffic enforcement observations target Uber and Lyft drivers as largest offenders

A recent scan from San Francisco’s Police Department found that Uber and Lyft drivers were responsible for nearly 65 percent of traffic infractions in bike- and transit-only lanes. The overwhelming majority of these tickets, for all vehicles and for Uber and Lyft vehicles, cited San Francisco Code 7.2.72 TC (see below), “Driving in a Transit Lane,” which comes with a $69 fine. There were also three felony and 29 misdemeanor arrests associated with this traffic report, indicating more serious incidents. Read More >

FDOT to deploy innovative transportation technologies for increased safety

The Orlando area has received a grant of close to $12 million to utilize innovative transportation system technologies to improve the safety of pedestrians and bicyclists and to ease congestion. The grant was awarded by an FHA that seeks ideal deployment sites for large-scale installation and operation of advanced transportation technologies. The program’s goals are to improve safety, efficiency, system performance, and infrastructure return on investment. Read More >

Distracted driving: a silent killer?

Representatives from the Property Casualty Insurers Association of America and NHTSA called distracted driving a “serious public safety concern” and a “crisis.” Yet there still doesn’t seem to be any compelling evidence linking the surging death rate to distracted driving. AAA reported earlier this month that in-vehicle touchscreens and voice activated systems could pose new problems. But the newest numbers from U.S. DOT—released the same week as the AAA report—show deaths related to distracted driving dropped 2.2 percent in 2016, while traffic deaths increased 5.6 percent overall.
