There hasn’t been a new highway tunnel built in California in 50 years, but new tunnels that will provide an alternative to a slide-prone stretch of the Pacific Coast Highway will be very impressive when they open.

One-way or two-way streets more efficient? It depends on what you measure
The debate over one-way versus two-way streets has been ongoing for more than half a century in American cities. Counter to prevailing engineering wisdom, a new study finds two-way streets may be more efficient, if one is measuring getting people to their destinations.
New York City’s subway train operators taking unilateral action to prevent fatalities at stations
Following two widely publicized incidents of waiting passengers being pushed into the path of oncoming subway trains, the Transit Workers Union has directed its subway train operators to slow trains to 10 mph when entering station areas to enable them to stop if riders are on the tracks. This and other solutions to accidental and intentional falls onto tracks are being examined in New York and cities around the world.
Measuring the Street: New Metrics for 21st Century Streets (New York City DOT, 2012)
This report discusses key approaches to street design projects, and how results can be measured against goals for safety, serving all users and creating great public spaces while also maintaining the flow of traffic.
Increasing bicycle mode share leads to growing need for bicycle-specific traffic signals
As the popularity of transportation bicycling continues to grow, traffic engineers, planners, and lawmakers are recognizing the need to incorporate bicycle-specific infrastructure into intersection designs. Bicycle-specific signals are being used in 16 U.S. cities, and the signals are being included in traffic control manuals. NACTO has excellent guidance for how and where to install these signals.
Kansas City faces public backlash over traffic signal removal plans
Kansas City, Missouri, is facing public backlash after embarking on a project to replace 144 of its aging traffic signals with stop signs at intersections where traffic has declined.
Solving the critter crossing problem
When state Departments of Transportation address safety concerns related to motor-vehicle/wildlife crashes, the agencies save lives and reduce economic costs. Crashes involving larger animals – including deer, elk, moose, and bear – are on the rise, and many states consider addressing this safety concern an integral part of their mission. Some states are using innovative approaches to keep wildlife off the roads.
Bike boxes and lanes may increase “right hook” crashes in some circumstances
A preliminary analysis of bike crashes at intersections in Portland with painted bike lanes, bike boxes, and bicycle-related signage has indicated that when placed on a downhill section of road, they may actually increase the number of bicycle/motor-vehicle crashes, especially during “stale” green lights.
Fighting transit fear with transit facts
While per-capita traffic casualties are declining with increasing transit ridership, many people still harbor an irrational fear of public transit—making them less likely to use transit or support increased transit service. Todd Litman of the Victoria Transport Policy Institute (VTPI) released a new study last month that delves into this issue.
“War on cars” (or bicycles) isn’t new
A recent NPR story asked if there was really a “war on cars.” This idea seems to appear in newspaper comments, on radio talk shows, and as opinion pieces. But this question is not new, nor are complaints about rude bicyclists or clueless pedestrians. We have been arguing about access and safety in the public right of way for over a century.
