Advanced SCAT Programming

GHA specializes in advanced programming for new and existing traffic systems. Our team skillfully manages the programming needs during construction, ensuring minimal disruption. Post-construction, we implement new programming designed to optimize traffic flow. This process involves close collaboration with our Traffic Data Collection Division, who utilize state-of-the-art technologies like MioVision Count and Synchro Traffic Model Simulation to ensure the most effective traffic signal and signal area management, resulting in the best outcomes in traffic flow and safety. 

SPECIALIZED TIMING CONSIDERATIONS IN SCAT

For our SCAT operations, we customize signal timing to accommodate various traffic scenarios. This approach ensures efficient traffic flow, with special attention to the dynamics of both AM/PM peak hours. Additionally, we develop specialized release plans for scenarios like school zones, aimed at facilitating smooth traffic movement throughout the day. Our expertise in adapting to different traffic scenarios demonstrates that our solutions are not only effective in regular conditions but also during critical high traffic hours.

LONG-TERM RELATIONSHIPS

For more than decade, we have proudly collaborated with Illinois District of Transportation (IDOT) District. This partnership includes weekly reports and in-depth assessments at intersections, aimed at improving traffic efficiency and safety. Our expertise covers monitoring, programming, and maintenance needs. Our work with IDOT also extends to Districts 2-5, dating back to 2008, where we’ve focused on optimizing traffic signal timings for improved corridor efficiency across these areas. Additionally, we have a strong presence with the DuPage Department of Transportation, having worked closely with them since 2017. These partnerships reflect our ongoing commitment to traffic flow improvement across multiple DOT districts.

IMPACT ASSESSMENT AND IMPROVEMENT IN SCAT

GHA’s approach in SCAT includes thorough impact assessments to optimize signal timings, focusing on enhancing traffic efficiency and reducing emissions. We conduct detailed evaluations, comparing conditions before and after reprogramming to quantify improvements in speed delays and environmental impact. This process involves several rounds of data collection and analysis, ensuring that our adjustments lead to tangible improvements in traffic flow and contribute positively to the overall environmental sustainability of the regions we serve.

Traffic Signal Design

At GHA, our traffic signal design process is thoughtfully crafted for optimal functionality and safety. We focus on the strategic placement of posts and mast arms, while considering all underground utilities. Our approach is grounded in a deep understanding of traffic dynamics, aiming to create seamless and efficient signal systems that cater to the needs of diverse traffic environments.

COMPLIANCE AND ACCESSIBILITY

We prioritize accessibility in our traffic signal designs. Adhering strictly to updated Public Right-of-Way Accessibility Guidelines (PROWAG) and Americans With Disabilities Act (ADA) standards, we specialize in integrating Accessible Pedestrian Signals (APS) at all new signal installations. Our team specializes in retrofitting and modernizing traffic signals and crosswalks to ensure ADA compliance. This includes the strategic installation of new pedestrian posts, a key modernization technique for integrating APS at existing signal locations. Our focus on these upgrades ensures that our designs not only meet regulatory standards but also enhance user experience, demonstrating our commitment to creating accessible and efficient urban infrastructure solutions.

CUSTOMIZED SIGNAL INSTALLATIONS

Our signal installations are custom designed to suit each location’s unique needs. With a forward-thinking perspective, we consider future Right of Way (ROW) needs and carefully plan to avoid any utility conflicts. Adhering strictly to the standards set by all governing bodies, we verify that each installation is not only compliant but also anticipates future expansions and requirements. This strategy reflects how we balance immediate needs with future community evolution.
