Field Systems Engineers:
We hope you have enjoyed the first year of our publication as much as we have enjoyed presenting it to you.
We here in the NYC, NJ and Long Island areas have “weathered” some tough times with Super Storm Sandy in this last quarter of 2012 and hope that those of you who were affected by this overwhelming storm are headed for a brighter year in 2013.
We wish all of our TSI friends a happy, healthy and prosperous new year.
For more than a decade, Traffic Systems, Inc. has partnered with Polara Engineering as their exclusive New York State distributor. Traffic Systems Inc. has successfully placed Polara equipment in NYSDOT, NYCDOT, Suffolk County, Nassau County and Monroe County.
Polara is an organization dedicated to producing the highest quality products through stringent design, development, and production techniques. Polara utilizes its expertise in design, production, and assembly to produce the highest quality products that perform in the most demanding applications. Best of all, all products are built in the USA!
Polara's Navigators Installed in New York City
Polara's EZ Communicator Navigator APS was recently installed in 21 intersections across New York City. New York City has plans to install equipment at an additional 25 intersections across the five boroughs by year-end. The newest Navigator APS was installed at the intersection of 7th Avenue and 23rd Street in Manhattan, one of New York City's most dangerous intersections for pedestrians. New York City news station NY1 reported that from 2005 to 2009, 21 pedestrians had been injured at the intersection, and one had died.
At a recent press conference held at this same intersection, residents of the neighborhood and advocates of street safety applauded the ADA-compliant upgrade. A few individuals with visual impairments were also on hand to applaud the installation and encourage the city to continue their efforts to meet the needs of all pedestrians. In all, New York City has over 11,000 intersections. Installing Polara's Navigator APS would help ensure the safety of all pedestrians in New York City.

Polara's Navigator Featured on ABC's Extreme Makeover Home Edition
Polara's Navigator Accessible Pedestrian System (APS) was recently featured on Extreme Makeover Home Edition. The home in the episodewas remodeled to accommodate a visually impaired individual. As part of the remodel, Polara's Navigator APS was installed at an adjacent intersection frequented by the individual. After remodeling and upgrading the home of the individual with a visual disability, the producers of Extreme Makeover contacted the city to upgrade the nearby intersection with an Accessible Pedestrian System specifically outfitted for blind and visually impaired pedestrians.

NYSDOT, in cooperation with Rensselaer Polytechnic Institute is preparing to install a Traffic Adaptive Traffic Signal System using Siemens' ACS Lite Traffic Adaptive Firmware.
The project corridor is on Wolf Road in Albany. There are 9 intersections in the system and the limits are from Central Avenue to the entrance to I-87 N, approximately 2 miles. The project will utilize the existing infrastructure including 2070 controllers, Model 330 cabinets and peripherals.
The existing controllers will have the Siemens’ Traffic Adaptive ACS Lite firmware installed. The controllers will communicate via an Ethernet communications link to a field installed Master computer. The local controllers will receive detection inputs from both main and side street detection. The information will be transmitted to the Master computer. The Master computer will then determine the system splits and offsets for each local intersection based upon demand.
The detection technology deployed consists of in-pavement sensors which are wireless magnetometers manufactured by Sensys Networks. Each sensor is equivalent to a 6 x 6 inductive loop. The sensors communicate wirelessly to a device called the Access Point (AP). Each AP has the capability to communicate via a 2.4GHz radio link with up to 48 wireless sensors. The data received from the Sensors by the AP is then converted to contact closures and interfaced into the traffic controller. The traffic controller communicates with the Master computer via an Ethernet link which passes the data for processing.
The magnetometers were installed at each intersection on the mainline (Wolf Road). Two “pucks” were installed per lane, approximately 15 feet apart starting at the stop line. Existing loops were utilized for side street phase detection.
The ACS Lite Traffic Adaptive Algorithm monitors vehicle presence, vehicle queuing and platooning. The information is analyzed by the Master computer to determine offset / split patterns which will efficiently move traffic by minimizing delays along the corridor. In order to properly evaluate the effectiveness of the ACS Lite system, additional Sensys Wireless Magnetometers were installed at four locations in each direction along the corridor to generate average travel times. The Sensys Magnetometers were installed in the left lane in five sensor arrays across the travel lane perpendicular to the direction of travel.
These arrays will provide a unique vehicle signature at each station to generate travel times along the corridor. The detector arrays will be utilized to generate both before and after travel times for determining benefits of the ACS Lite Traffic Adaptive system.
