Using the “left digit effect,” a group of researchers slowed drivers’ speeds with a simple change on speed limit signs.
Outcomes
Buffalo has reshaped mixed-use development by eliminating parking requirements
After eliminating its minimum parking requirements in 2017, the city of Buffalo, New York, has seen a notable drop in the growth of new parking, driven mostly by changes in mixed-use developments.
Road pricing reduces induced demand
A new study confirms that adding capacity to roads generates an exactly proportional increase in vehicle travel. Road pricing curbs this effect.
Bundling transportation projects can squeeze out smaller firms
Bundling projects can lead to less competition and can squeeze out smaller minority- and women-owned businesses in favor of larger national and international firms.
Using a transit route diversity index to measure spatial equity
A recent study by researchers at the Hong Kong Polytechnic University uses a route diversity index to measure resilience and accessibility on a fine scale for planned Mass Transit Railway expansions.
Inequitable street space for transit and cyclists common, even in urbanized areas
A new study shows that transit riders and cyclists have significantly lower surface area allocated to them for exclusive use compared to demand.
Seattle’s reduced parking minimums cut 18,000 stalls and saved over $500 million
Based on costs of providing parking in Seattle, the authors estimate the reduction in parking capacity saved some $537 million.
Fewer stop lines could help agencies save maintenance costs
A 14-year study from the University of Minnesota demonstrates that painted stop bars at intersections have little effectiveness in reducing collisions or influencing motorist stopping position.
Road Designers Can Protect Against Distracted Driving
Important new research shows that road design actually plays an important role in curbing the most dangerous consequences of distracted driving.
Cleveland MPO Will Consider Broad Economic and Equity Impacts of Interchange Projects
The Northeast Ohio Areawide Coordinating Agency (NOACA) has adopted a policy to evaluate whether to fund proposed highway interchange projects based partially on their regionwide economic impacts, which communities will benefit, and which may experience decline and other negative long-term effects as a result.
