Eyes on the Street: New 30 MPH Speed Limit Signs on Riverside Drive

According to DOT, as of November 7 the maximum legal speed on 90 percent of city streets is 25 miles per hour or lower. Regarding the criteria for exceptions to the new 25 mph default speed limit, a DOT FAQ sheet reads as follows:

One street that now has a 30 mph posted speed limit is Riverside Drive, which is lined with residences and parks for most of its length, from the Upper West Side to Washington Heights. The above photo was taken this week at Riverside and W. 114th Street, in Morningside Heights. This was no DOT oversight. The sign, along with other 30 mph signs posted on Riverside, were installed this week.

According to crash data mapped on Transportation Alternatives' CrashStat, just about every Riverside intersection saw at least one motorist collision with a pedestrian or cyclist between 1995 and 2009. In 2005 a driver killed a cyclist at Riverside and W. 115th Street, less than a block from where this photo was taken.

As the DOT FAQ says, "Data shows that driving at or below 25 MPH improves drivers’ ability to avoid crashes. Pedestrians struck by vehicles traveling at 25 MPH are half as likely to die as those struck at 30 MPH." With a 30 mph speed limit, Riverside Drive is not as safe as it could be.

"Riverside is a major commuting and recreational cycling route, and is plagued by speeding," wrote the reader who sent us the photo. "Who decided that this cycling thoroughfare and neighborhood street should have a higher speed limit than most of the rest of the city?"

DOT is closed for Veterans Day. We emailed to ask what the rationale was for 30 miles per hour on Riverside, and will update here if we get a response.
