Reference marker

In New York, a reference marker is a small green sign mounted approximately every one-tenth mile on highways maintained by the New York State Department of Transportation. This was initiated in response to the Highway Safety Act of 1966 enacted by Congress, in an effort to monitor traffic and identify high-accident locations. New York's system inventories and indexes all touring and reference routes, in addition to service and rest areas, ramps, and reservation roads. New York's system is similar to California's postmile system in maintaining the state's highways and route logs. The New York State Thruway Authority adopted its own reference system for the New York State Thruway system, including I-287. There is a similar reference marker system in use in neighboring Vermont.
