Back in January the city’s Department of Transportation published a report that seemed to indicate the overwhelmingly beneficial effects of the epically disputed Prospect Park West bike lane, like dramatically reduced speeding, fewer accidents and virtually no additional gridlock. Auto-dependent borough president Marty Markowitz wasn’t buying it; nor was the small group of well-connected Park Slopers currently suing the city to have the lane removed, who were quick to dispute the apparent benefits. Now the NIMBY group is picking apart specific stats from the DoT report.
The New York Daily News reports that the lane-haterz are calling into question several figures from the report and the methods used to obtain them. Among these they note that the two locations on PPW where the speed of cars was measured to have dropped to an average of 26.6mph overstate the difference from the pre-lane average of 33.8mph measured at three locations. The Daily News notes: “Using all the locations would have shown a more modest speed drop.” But modest drops≠sufficient drops, the group seems to be suggesting.
The group also alleges that by measuring speeding over only one year—whereas it concluded that accidents plummeted (still a benefit, right?) based on three years worth of evidence—the DoT report claimed a 21.3% drop in the average car speed on Prospect Park West while, measured differently, the numbers suggest a speed reduction of only 2.6% on the stretch.
In other words, it’s all insanely nit-picky and suggests that perhaps extremely positive effects of the two-way bike lane on Prospect Park West may only be moderately beneficial results, which is definitely a shortcoming worth suing over, right?
