Bus lanes are travel lanes that are restricted to buses during certain hours of the day. All bus lanes have signs posted along the route with specific regulations; lanes marked "Bus Only" and /or painted red. Bus lanes help to keep buses from getting stuck in traffic, generally making travel for bus riders faster and reliable and improving the overall traffic flow of a corridor. Each record represents a segment of a bus lane based on the LION geographic base file of NYC streets. User may use the SegmentID field in this dataset to join with the LION data for more information.
