Nassau County DPW, PW-H6200002E – Traffic Management Center Operations, sub to Greenman-Pedersen, Inc., 2013 – On-going
The Traffic Management Center (TMC) consists of control of over 900 traffic signals throughout Nassau County utilizing Siemens Actra control software. The TMC has the ability to control all aspects of the traffic signal controller including signal timing, splits and offsets. In addition, the TMC will have control of over 100 traffic incident management surveillance cameras utilizing Teleste control software. Problems identified utilizing the traffic incident management cameras, vehicle speed sensors, public safety radio communications, or telephone calls can initiate the adjustment of traffic signal timing in order to reduce vehicular congestion and delays.
Operations personnel, upon identifications of problems along County roadways, take the appropriate actions to address the issue such as notification of emergency services, public works, and/or making the appropriate adjustments to the area traffic signals. Efforts include coordination of information between office, administrative and field personnel with other State, County and local agencies to mitigate traffic congestion issues.
Operation personnel also analyze existing traffic signal timing and coordination to determine the need for adjustment, ensure proper back-up and archive of traffic signal timing, speed data, and video as needed, coordinate planned and un-planned roadway and traffic events, dispatch maintenance or supervisory staff as needed to address signal, camera or communications deficiencies, and perform traffic signal and intelligent transportation systems related work such as timing plan modification, signal coordination, travel time study analysis and synchro analysis.

Nassau County DPW, CQPL06000005 – Traffic Signal Progression Project, 2006 -2009
Under this major signal timing analysis project, Wiley was tasked with improving the signal coordination for the entire controlled length of Merrick Road between the Queens/Nassau border and the Nassau/Suffolk border. Some of the tasks included under this project were turning movement counts at selected intersections, field visits to each intersection to observe signal timing, condition of signal controller and detector operation, travel time runs and use of PASSER and Synchro software applications. The resulting report will recommend signal operation modifications to improve the overall signal progression along the Merrick Road corridor.

Stony Brook University, Evaluation of Traffic Safety Improvements at Various Campus Locations, 2006
Wiley Engineering first reviewed all previously submitted plans and documents pertaining to traffic and safety improvements in the subject areas and then observed the existing traffic and pedestrian patterns at various locations at different times including walking speeds, gaps in traffic, conflicts with vehicles, understanding and compliance with existing control devices and exhibited pedestrian behaviors (running, stopping looking etc.). Included in the review were the existing local posted speed limits and actual prevailing vehicle speeds as they relate to pedestrian safety. We also performed pedestrian volume counts at various locations and times, and reviewed the existing traffic signal operation at Health Sciences Drive and HSC III and made recommendations on signal upgrades and revisions to speed limits.
