Using Big Data for estimating VMT and reliable travel patterns

By Saumya Jain For the longest time we’ve relied on the Highway Performance Monitoring System for understanding travel patterns and estimating vehicle miles of travel. But these estimates often have not been very accurate because of inadequacies in data collection. Big data is providing more

Forecasters guarded about EV share of VMT

By Michael Brenneis A smooth and equitable transition to a low-carbon global economy is an essential component in the mitigation of anthropogenic climate change. But migration away from a long-entrenched fossil energy system has its challenges. Adequate and consistent carbon emission reduction

LOS to play more limited role in California planning, according to survey

By Chris McCahill A new survey of planning officials in California finds that most are embracing the shift from highway level of service to vehicle miles traveled for evaluating the environmental impacts of new development projects. While some are ditching LOS altogether, however, many still rely

How might travelers behave with privately-owned AVs?

By Michael Brenneis In many ways, we can only speculate about a future with autonomous vehicles on the road. The effects on vehicle miles traveled are expected to be very different if AVs are privately owned versus shared. A recent post by Aaron Gordon on Jalopnick drew our attention to a

UK scientists warn of resource costs in transitioning to net-zero emissions by 2050

By Michael Brenneis The necessary transition away from burning fossil fuels for transportation could be quite resource intensive. So say leading UK scientists in a recent letter to the UK Committee on Climate Change, in response to their recommended target of net-zero greenhouse gas emissions by
