Thanks to federal funding from Safe Streets and Roads for All (SS4A) and changes to the MUTCD, #MadisonWI is moving forward with a series of asphalt art projects. The first one will hit the streets in September.

States rethink a long-held practice of setting speed limits based on how fast drivers travel Road safety activists and some states are pushing to depart from a longstanding rule that sets speed limits in the United States based largely on how fast drivers actually travel.

States are rethinking a long-held rule that often calls for speed limits to be *raised* on roads with excessive speeding.

#MadisonWI is one community taking a different approach, says @apnews.com.

One noteworthy detail: the typical community that benefited under the previous Justice40 initiative was around 52% Trump supporter. Under the proposed new policy, that moves to 73%.

How SUVs Are Making Traffic Worse As larger, taller sport utility vehicles took over US roads, they also aggravated highway congestion, according to a new study. It’s yet another ill effect of β€œcar bloat.”

A groundbreaking new study found that the surge in SUVs from 1995 to 2019 reduced Minnesota's highway lane capacity by 9.5%.

Less lane capacity --> More congestion

Many states are counting on strong electric vehicle sales to meet ambitious climate goals. Without federal incentives, reaching those targets will require much more local effort.

NYC Sees Pedestrian Traffic Increase in Congestion-Pricing Zone Pedestrian traffic on New York City’s busiest streets increased in January even after motorists began paying a new toll to drive into those same neighborhoods.

And the latest reports suggest the number of people walking inside New York's congestion pricing zone increased 4.6%, compared to last year. This increase is almost three times larger than outside the pricing area.
