Pedestrian Ramps Surveyed


A detailed inventory of New York City’s pedestrian ramps has been completed as of October 2019. We used high definition, street level imagery, ground-based LiDAR technology, and car-mounted equipment to collect terrain and image information on two or more recorded runs for the data collection.

How Are We Going to Use This Data?

NYC DOT is now in the process of assessing the data extracted from LiDAR and imagery data collected for each pedestrian ramp. We will determine whether a ramp needs an upgrade based on design standards of the Americans with Disabilities Act. We will start with ramps that are on newly resurfaced streets and ramps in connection with complaints. Next, we will combine survey data with demographic information to determine where to continue our work on a priority basis. We will complete the full assessment by October 2020. DOT’s continued assessment and quality assurance work on the survey data until October 31, 2020 may change the number of ramps published at the survey end date.


Survey Map

The map below illustrates the location of ramps where a survey of a pedestrian ramp has taken place. As of May 31st, 2019 there are a total of 215,416 ramps surveyed across all 5 boroughs. For an accessible version of the map visit the Find Surveyed Ramps by Street Intersection section. Please note the map does not reflect results of the survey only if a location has had a survey.



The information above shows locations with existing, surveyed pedestrian ramps. If a dot is not shown, the location was not surveyed or has no pedestrian ramps. DOT will add additional locations to the map on a rolling basis throughout the ongoing survey. Locations that do not have ramps will be evaluated for installation following completion of the survey. Please note that this information may contain errors and may not be complete.
