The Gwinnett Place CID Board of Directors has identified traffic congestion and efficient traffic management as priority issues. In order to clearly identify the best projects to mitigate traffic congestion and enhance the efficient flow of traffic in the area, the Gwinnett Place CID, along with funding from the Gwinnett County Board of Commissioners, have completed various comprehensive transportation studies to determine viable traffic relief strategies that could be implemented in the next few years. Click the links below to view the transportation study that identified potential intersection improvement solutions along the Pleasant Hill Road, Steve Reynolds Boulevard and Satellite Boulevard corridors. An update to the traffic study was released September 2016.

Three Intersection Improvement Projects along Venture Drive:
The Gwinnett Place CID and Gwinnett County DOT are undertaking three projects that will improve the Gwinnett Place Drive at Pleasant Hill Road, Venture Drive at Day Drive and Venture Drive at Steve Reynolds Boulevard intersections in order to provide better connectivity within the CID area.
Pleasant Hill Road at Gwinnett Place Drive/Venture Drive Intersection Improvement Project: Project plans and right of way acquisition have been completed for the Gwinnett Place Drive/Venture Drive at Pleasant Hill Road project, and construction was completed in January 2017. The project included a shared right turn lane and through lane across Pleasant Hill Road and provide southbound access to Gwinnett Place Drive by adding a left turn access from eastbound Pleasant Hill Road. As part of the project, the traffic signal and pedestrian facilities at the intersection were also updated.
Venture Drive at Day Drive Intersection Improvement Project: The Venture Drive at Day Drive project is in preliminary design. Right of way acquisitions began in mid-2016, and the project will begin construction after the right of way acquisitions are complete. A roundabout is proposed to be constructed on Venture Drive at Day Drive in order to improve traffic flow and reduce conflict points in the congested area.
Venture Drive at Steve Reynolds Boulevard Intersection Improvement Project: The Venture Drive at Steve Reynolds Boulevard project is in preliminary design. Right of way acquisitions began in mid-2016, and construction expected in late 2017. Venture Drive will be widened at the corner of Steve Reynolds Boulevard in order to construct a designated northbound right turn lane onto Steve Reynolds Boulevard. This second northbound through lane on Venture Drive will continue across Steve Reynolds Boulevard and convert another existing right turn lane into a continuing through lane crossing the intersection and terminating at the retail shopping center North of the intersection.

Club Drive at Pleasant Hill Road Intersection Improvement Project:
The Club Drive intersection improvement project has completed design and finalized acquisition of right of way. Construction will require intermittent lane closures through August 2017 for the intersection roadway improvements. Any such closures will be done between the hours of 9:00 a.m. and 4:00 p.m. Completion time is contingent upon actual weather conditions, utility conflicts encountered, etc., which may shorten or lengthen the project time. The project will improve the intersection and install northbound triple left lanes on Pleasant Hill Road to replace the existing dual left turn lanes. The project will install eastbound dual right lanes at Club Drive to replace the existing single right turn lane. These added lanes should help alleviate traffic delays and facilitate better movement through the intersection.

Pleasant Hill Road at Breckinridge Boulevard Intersection Improvement Project:
In partnership with the CID and as a result of a GPCID Traffic Study, Gwinnett County DOT has completed construction of improvements to the intersection of Breckinridge Boulevard at Pleasant Hill Road. The project was funded through the 2014 Special Purpose Local Option Sales Tax (SPLOST) program and was completed in late July 2015. The project consisted of removing the existing striped island in order to add a second left turn lane. The project also included removal of approximately 60 feet of existing center median island planter on Breckinridge Boulevard to lengthen the existing southbound left turn lane, turning east onto Pleasant Hill Road. The completed project provided two 250' turn lanes to better accommodate the volume of traffic at the intersection.
Traffic Responsive System Operational
- The first task is System Control. The intersections in the system communicate through Ethernet switches over fiber optic cable back to the Gwinnett County Traffic Control Center (TCC). Wolverton will be utilizing the existing communications to connect the signals to the central server at the TCC. This will allow the intersections to be monitored from the TCC or remotely multiple times per second. This connection allows for the time clock at each intersection to be automatically checked and synchronized, if needed. Many of the timing issues that arise in signal systems come from the local clock at each intersection not being synchronized and not from timing problems. System Control also allows for manual specialized timings to be implemented with one click. Normally, changes would have to be made at each individual intersection to make a change to the system – meaning for the CID’s system, the changes would have to be made 49 times. During the 2014 snow storms, the system was changed from the normal timings that run during the peak time periods to timings that allowed the green to come up much faster on any approach. This change prevented cars from getting stuck or spinning tires because they had to stop at the intersections. The changes had to be made 49 times to put the timings into the system and again 49 times to put normal timings back in.
- Traffic engineers take the data observed through the detectors in Task 2 and use that data to create signal timings. These plans layout the cycle of the traffic signals at the intersection to get the most amount of traffic through an intersection in any given cycle. The engineers set thresholds for volume and direction and then program the signals to run specific timings at specific times of day or at specific volumes of traffic. These plans will be incorporated in Task 3.
- The third task is Traffic Responsive Operation. Traffic Responsive Operation is an underutilized method of signal control throughout the state. The Georgia Department of Transportation has a current project called the Regional Traffic Operations Program (RTOP) which has utilized this method of signal timing on over 300 signals along 11 corridors in the metro Atlanta region. Several other projects have implemented this method to a smaller scale as well. Traffic Responsive Operation takes the signal timings created by the traffic engineers and calls up the appropriate timings for the system based on the thresholds designed in the timings. This method of signal control doesn’t necessarily improve the peak traffic in the system, as the plans that are already running are highly optimized. However, this method does improve the off-peak and fringe-peak timings greatly because it can adapt to sudden changes in volumes very quickly.
There are several examples of where this is beneficial to the public. The best example is Thanksgiving weekend. With normal signal operation, the normal Thursday timing plans would run on Thanksgiving Day and the normal Friday timing plans would run on Black Friday. With Traffic Responsive Operation, the system would recognize that Thursday traffic is very light and use a timing plan to accommodate the actual traffic conditions, reducing side street delay. On Friday, the system would recognize that traffic is much higher during the entire day and use a timing plan that is appropriate to handle the increased traffic.
This project has been a great benefit to the traveling public throughout the Gwinnett Place CID area. The ongoing investment that the CID Board is making into the traffic signals in the area has made the Gwinnett Place CID signal system one of the most efficient signal systems around, with very quick response to citizen complaints, short down time of traffic signal detection and displays and active signal timing adjustments based on traffic conditions.
