Engineers at the Virginia Department of Transportation (VDOT) are studying a new type of asphalt mixture, called recycled plastic modified asphalt mixture (RPM), that could replace traditional asphalt mix. While limited research on the technology says it is a win-win for both improving longevity of roads and redirecting plastic waste from landfills, VDOT wants to confirm that the new mixture does not result in microplastic entering the environment through water runoff.
By Chris McCahill There is an important growing consensus around the need for achieving net zero carbon emissions by 2050. The White House, Ford Motor Company, and many state and local governments seem to be …
By James Hughes More state and local agencies are investing in high-capacity transit lines to ease pressure along busy corridors. While the added capacity can relieve traffic congestion in the short-term, new research suggests that—just as with new …
By Michael Brenneis Changed travel behavior during the COVID-19 pandemic has reduced congestion and vehicle miles traveled (VMT), even while traffic deaths continue to rise. Evidence shows that open roads, speeding, and other dangerous driving behaviors …
State DOTs are essential participants in the fight against climate change, but also face competing demands. For the Colorado DOT (CDOT), that means navigating its responsibilities to maintain and improve existing highways, improve rural access, and reduce congestion, all while reducing greenhouse emissions.
Transportation agencies in California and Minnesota made major advancements, planning for VMT reductions and mitigations as a part of their sustainability and climate change plans.
Despite frequent claims to the contrary, a study from California demonstrates that telecommuters often drive more often, and for longer distances, than those who commute to work.
A surprising impact of the evening commute: traffic noise and other human-made sounds significantly disrupt the mating behavior of crickets.
Amid talk of electric and fuel efficient vehicles, one change proved fast and effective at cutting emissions: traveling less.
More research is emerging showing that EVs are not the “silver bullet” in reducing transportation climate emissions.
