Case Studies – Traffic Signals
Case Study-
Adaptive Traffic Signals
challenge
The City of Casa Grande needed a solution to improve traffic efficiency on Florence Blvd. This need arose due to population growth from expanding manufacturing, logistics, and healthcare industries.
solution
The city partnered with Clark Transportation Solutions, implementing Swarco McCain Transparity Central and Adaptive Software, alongside Gridsmart detection. This combination delivered improved traffic flow and system reliability.
result
The project reduced travel time along Florence Blvd and added capability for the traffic signal intersections to dynamically change signal timing in response to incidents.

Case Study-
ATC Cabinet at Bowlin and White Parker
challenge
City has growing infrastructure needs as roadways are improved and widened.
solution
The agency is investing in traffic infrastructure upgrades to enhance roadway safety and accessibility.
result
The city is leveraging the latest traffic signal technology and selected Clark Transportation Solution due to our experience integrating a complete traffic signal solution.
“The installation of traffic signals goes beyond mere functionality; it’s a strategic investment in the future of our city,” City of Maricopa Mayor Smith explains. “While the upfront costs may be substantial, averaging around $1 million per intersection, the safety for our residents is worth it.”

Case Studies – Outdoor Lighting
Case Study-
Citywide lighting conversion
challenge
The city faced rising maintenance costs due to the operation and repair of high-pressure sodium luminaires.
solution
The city opted for energy-efficient LED lights to lower maintenance costs and improve roadway safety through better lighting performance.
result
The City of Peoria selected GE Evolve LED lights for their performance and reliability in Arizona’s hot, dusty climate. Starting in 2019, they upgraded 4,500 fixtures on arterial and collector roadways. This energy-efficient lighting reduced the total cost of ownership, achieving an estimated 57% energy savings per fixture.


Case Study-Streetscape
challenge
The City of Scottsdale desired to modernize and upgrade the street light infrastructure in its iconic downtown area.
solution
Clark Transportation Solutions collaborated with City of Scottsdale, CS Construction and Kimley Horn to enhance the historic streetscape, delivering a durable, long-lasting upgrade.
result
The custom-engineered Valmont wagon wheel poles, featuring unique powder-coated elements, draw inspiration from Main Street Scottsdale’s medallion statue, symbolizing the town’s rich history. The lights will be strung between the poles, adding an extra layer of charm to Old Town Scottsdale.




Case Studies – Intelligent Transportation Systems
Case Study-Fiber Networking
challenge
Agencies need increased fiber optic network redundancy to future proof the network against network outages from accidental digging. Network connectivity provides the bandwidth to support sending mission critical signal operation data across agency networks.
solution
The City of Goodyear partnered with EtherWAN to design and implement a core network upgrade utilizing 10 gigabit core switches. The EG97023-2VCR provides redundancy with multiple routed paths.
result
Agency has future proofed network with increased bandwidth for transmitting data along with greater network reliability.

Case Study-
Wireless Connectivity
challenge
Agency needed connectivity in hard to reach areas where fiber is not available to support regional traffic operations.
solution
Regional Transportation Commission of Southern Nevada partnered with Clark Transportation Solutions and Encom Wireless to fill that need deploying Energy INT wireless radios with Encom Wireless Stratos software.
result
RTC has the connectivity to implement traffic operation adjustments in real time to traffic signals.

Case Studies – Roadway Safety
Case Study-Emergency Pre-Emption
challenge
First Responders need reliable technology to reach emergency calls quickly and safely.
solution
Tomar smart optical emergency pre-emption technology with confirmation light allows emergency vehicles to safely traverse heavy traffic situations and get through intersections on a green light.
result
Agencies have experienced operational and safety benefit by utilizing Tomar emergency pre-emption.

Case Study-
Neighborhood Traffic Calming
challenge
Many agencies have experienced a rise in pedestrian-related safety incidents on roadways.
solution
To enhance roadway safety for vulnerable users, the City of Tempe leadership adopted Vision Zero, a strategy to reduce traffic fatalities and severe injuries.
result
The city chose to implement Carmanah SpeedCheck solar speed feedback signs in neighborhoods as part of their Vision Zero safety plan.
