NYSTA ITS Field Equipment
NYSTA ITS Field Equipment consists of physical installations of ITS equipment such as Closed-Circuit Television cameras, Dynamic Message Signs, and Road Weather Information Systems (RWIS). The NYSTA Variable Length Barrier allows changes to lane configurations to accommodate variations in traffic flows based on time of day. The barrier can also be opened to release traffic that is "trapped" in a queue due to an unplanned event or incident. NYSTA Lane Use Signals (or lane control lights) are a specific type of traffic light used to manage traffic on a multi-way road or highway. Typically, they allow or forbid traffic to use one or more of the available lanes by the use of Green lights or arrows (to permit) or by red lights or crosses (to prohibit). When used, they are usually repeated at regular distances to provide a continuous reminder of the lane status to drivers. Reversible lanes and their associated field devices allow for the control of traffic flows and mitigates congestion on NYSTA roadways. NYSTA Access Gates are used to control and restrict vehicular traffic from NYSTA roadways in times of severe weather or other unplanned incident.
