Connecting Sacramento

accessibility4

Connecting Sacramento is the first study to incorporate both accessibility analysis and tripmaking data, including data from multiple sources, and assess how they can be used together to guide transportation- and land use-related decisions. This study focused specifically on opportunities to improve first- and last-mile connections to light rail transit in Sacramento, but its findings are widely applicable. Read More >

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.

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...

Multimodal transportation and income equity fit hand-in-glove

One recent study finds that cities offering diverse transportation options have the lowest income inequality, while another study finds that transit systems may begin to struggle as lower income families are pushed away from the city center. These works demonstrate that preserving access to multimodal options for disadvantaged populations is essential for cities’ economies, the viability of their transportation systems, and the wellbeing of families.

FL city tickets black population, misses on pedestrian safety

A new report by ProPublica and the Florida Times-Union details how efforts to ostensibly improve pedestrian safety in a Florida city consistently ranked as one of the most dangerous places to walk in the U.S. have actually resulted in inequitable ticketing of the city’s black population. The report points out that this is especially unfortunate because the same black and low-income neighborhoods where a majority of tickets were issued also lack safe pedestrian facilities: transit access is poor and many bus stops do not sidewalk connections.

California blocks parking requirements where housing needs aren’t met

In an effort to streamline affordable housing development, a new California law (SB-35) will preclude cities from requiring parking on certain projects, beginning January 1. Parking can drive up housing costs considerably and often isn’t needed. Read More >

Access to jobs by transit is on the rise

In most large metropolitan areas, the typical worker could reach more jobs by transit in 2016 than in 2015, according to the newest Access Across America report from the University of Minnesota’s Accessibility Observatory. Accessibility increased in 36 out of 49 regions. These annual reports let individual regions track changes in accessibility over time, scan for accessibility issues within the region, and compare their own performance to other regions. Read More >

Cities and airports look to develop best practices for rideshare pick-ups and drop-offs

As the demand for ridesharing services such as Uber and Lyft is exploding in many U.S. cities, pick-ups and drop-offs in high-traffic locations with limited curb space can create safety and congestion concerns for passengers, drivers and other street users such as bicyclists. Cities are beginning to experiment with solutions by creating dedicated zones for pick up and drop off of passengers. Read More >
