NACTO releases safe speed limit guidance

As the transportation field gradually moves away from its singular focus on high motor vehicle speeds and its reliance on motorist behavior to set speed limits, NACTO has just released comprehensive guidance on speed limits on surface streets in metro areas.

Destination access bills introduced in U.S. House

A trio of U.S. House members along with 10 co-sponsors have introduced a pair of bills that would set destination access as a national performance measure. Both bills describe destination access, aka “accessibility,” in terms of travel times by auto, transit, walking, and biking, with consideration for traffic-stress levels on the active modes. One of the bills focuses on access to employment, while the other focuses on access to non-work destinations such as shopping and schools.

Planning for an uncertain future

Traffic forecasts and other projections are often presented as a single line on a graph or number in a chart. But we know—now more than ever—that these predictions are full of uncertainties. The Sacramento Council of Governments (SACOG), for a new study in JAPA, puts hard numbers to some of those uncertainties in order to plan better for them.

Sweden and Virginia: Messaging and variable tolls can influence mode choice

Two recent studies demonstrate two approaches to reducing driving. A Swedish study looked at what types of messages influence the choice to drive, while a report from Virginia shows that tolls on the I-66 corridor outside Washington have made a difference in both mode choice and when drivers travel.

Framing resilience for state DOTs

The mission of many state DOTs has evolved beyond the traditional “highway department” to include protecting the quality of life of the people of a given state, and the integration of all travel modes to safely move people and goods. Resilience has come to mean more than the quick and cost-effective restoration of roads after a disaster. Acknowledging this, a new paper in Transportation Research Part D focuses on resilience in theory and practice, and explores a framework for the discussion of resilience within state DOTs and the development of resilience strategies.
