    ...So much time has passed since the law was signed a year ago, after five vetoes in previous years, that some drivers might have forgotten about it, especially a key component. It becomes law Sept. 16. The version that will take effect does not allow drivers to cross a double-yellow line to pass. If they can’t abide by the new 3-foot rule, they must slow to “a safe and reasonable speed” when passing. Vetoed versions of the bill allowed drivers to cross double-yellow lines to pass bikes at a safe difference.

  • University of Utah researchers are getting a better picture of Utah's air quality thanks to mobile sensors. The launch of the new project this week follows two seasons of poor air quality on the Wasatch Front. In the winter, particulate matter gets trapped in the ugly inversions that we see. In the summer, ozone is the problem.

  • Q: Oh Mr. Wizard of all things traffic, I ask of you, with the new law stating I have to stay three feet away from bicyclists, how am I supposed to do this when they ride four abreast on a two-lane street, ignore stop signs, don't wear helmets and just ignore rules and regulations. I can be cited but they go unabated?

     What makes the Prius so fuel efficient? The hybrid drivetrain is a big part of it, yes, but put that into a box on wheels like the Mercedes-Benz G-Wagen or even a Kia Soul and it’s not nearly so helpful. The Prius can deliver 51 mpg in no small part because Toyota engineers toiled tirelessly at their computers and in the wind tunnel to ensure it slices through the air as effortlessly as possible. Yet compared to the Schlörwagen, a German experimental vehicle from 1939, the Prius is a brick.

  • A study of air pollution reduction measures over the past ten years in Taiyuan, China, shows more than 50% of health costs associated with loss of life and disability have been saved as a direct result of the regulations’ implementation. 

  • ...For the most part, the people who run the New York City's myriad transportation organizations still haven't figured out how to deal with the most important, most obvious innovation in transportation: the smartphone...While cities and transportation regulators have released data and encouraged innovation through contests andhackathons, no U.S. city has aggressively pursued development of an integrated app that enables users to plan, book, and pay for trips across multiple travel modes. Instead, it's the likes of Uber and Google Maps and CityMapper and RideScout that have demonstrated what is possible, and controlled the movement market to date.

    A big reason for opposition to bike lanes is that, according to the rules of traffic engineering, they lead to car congestion...But the general wisdom doesn't tell the whole story here. On the contrary, smart street design can eliminate many of the traffic problems anticipated by alternative mode elements like bike lanes. A new report on protected bike lanes released by the New York City Department of Transportation offers a great example of how rider safety can be increased even while car speed is maintained.

  • ...The FHWA monthly "Traffic Volume Trends" report shows that drivers traveled 261.7 billion vehicle-miles traveled (VMT) in June, which according to FHWA is the most since June 2010. Travel on all roads increased by 3.7 billion miles in June, 1.3 percent more than June 2013. June also showed the largest single-month gain this year and the fourth consecutive month of VMT growth.
