We are currently conducting a detailed survey to evaluate the condition of existing pedestrian ramps using high definition, street level imagery and ground-based LiDAR data to extract measurements of each pedestrian ramp. We are taking various measurements for each ramp and will use this data to plan construction work accordingly. The pilot phase of the survey is nearing completion, with full, citywide data collection slated to begin this summer. By the end of 2019, all pedestrian ramp surveys will be completed, an unprecedented achievement for the City of New York.
