The first time I counted bicycles in traffic was in 1988. There were rumors that Mayor Ed Koch was going to reinstate the Midtown bike ban that a judge had set aside the previous summer. As president of Transportation Alternatives, I dispatched a team of volunteers to Midtown avenues with clipboards and stopwatches. Our finding that bikes accounted for 8-10 percent of vehicles in Midtown traffic was independently confirmed by the city DOT commissioner. With cycling's presence statistically validated, talk of the bike ban faded.

Maybe it was the NYPD's revenge for the disgracing of rookie cop (and detective's son) Patrick Pogan, now on trial for his brutal takedown two years ago of Critical Mass cyclist Christopher Long. Or perhaps it was just the latest manifestation of the post-9/11 security state, in which everything -- parked bikes, basic mobility, even human life -- is sacrificed on the altar of authorities' notion of safety.

Work crews will soon start clearing dozens of downed trees from Henry Hudson Drive, the New Jersey road whose spectacular vistas and challenging hills have made it a prime destination for New York-area cyclists. If all goes well, it may re-open as early as next month. But the scale of the devastation along the eight-mile route from Edgewater to Alpine, just across the George Washington Bridge, is adding weight to concerns over the impact of climate change on landscape and infrastructure.

It’s not often that you get to see your work set off a Eureka moment for someone else -- particularly when that someone is from a different culture. But I had that experience recently, and it seems worth sharing on Streetsblog in light of the interest shown today in my analysis of the travel delay costs from FreshDirect deliveries.

The pending trial of alleged 9/11 mastermind Khalid Shaikh Mohammed has thrown lower Manhattan into a tizzy, for good reasons. Foremost, of course, is the dread of revisiting the horrors of that day, mingled with fears of new attacks linked to the trial. But there are also concerns that the NYPD's aggressive countermeasures will impede movement, worsen traffic and suffocate the economy of the area, pockets of which never recovered fully from police-ordered street closures and other 9/11 aftershocks. These concerns could be assuaged by a tough, zero tolerance stance on parking placard abuse by government employees.

A prime target of the early environmental movement was car tailpipes. And for good reason. Put a human in a garage with a running auto in the old days, and he or she would pass out within minutes and be dead in an hour. Run a few million vehicles daily in New York or Los Angeles, and the toxic air would kill thousands each year and sicken many more.

Outside of China, only two cities of more than a million people are known to have a bicycling mode-share over 30 percent: Amsterdam and Copenhagen. As Rutgers urban expert John Pucher has documented, cycling's vibrantly high percentage of urban trips throughout Denmark, the Netherlands and Germany was not the product of amorphous cultural factors. Rather, it came about through public policies that not only made cycling safe and convenient but also made driving costly and cumbersome.

Miles and miles of bike-friendly Westchester County roads may soon be scarred by a "safety enhancement" that could make cycling treacherous.

New Yorkers could spend a third of a million more hours a year stuck in traffic if the “grace period” for parking violations voted by the City Council this week becomes law.

The surcharge on NYC medallion taxi fares that took effect this month is a bit like a bases-loaded groundout that scores a run but kills a big inning: It does some good, but a ringing base hit could have done a lot more.
