The Maricopa County Department of Transportation embraces innovations and technology to help operate and maintain its roads. Here are some of the technologies MCDOT is currently using or developing to improve transportation across Maricopa County.

Connected Vehicles

The transportation industry is on the cusp of embracing new technologies that will revolutionize the way we move. Connected and autonomous vehicles will have the ability to increase safety, improve mobility and reduce environmental impacts. The Maricopa County Department of Transportation (MCDOT) is a national leader in the field of connected vehicle technology. Read more about the Connected Vehicles Program.

MCDOT's Traffic Management Center

The goal of the Maricopa County Department of Transportation's Traffic Management Center (TMC) is to help provide county residents with a safe and efficient transportation system. The TMC is staffed and/or monitored 24 hours a day to respond to roadway incidents and communicate the latest traffic information.

Real-Time Traffic Management

TMC staff members monitor and analyze information from a number of sources including CCTV cameras, road sensors, public safety monitors and radios, the media and its AZTech regional partners. This information allows TMC staff members to respond to traffic incidents by adjusting signal timing, deploying incident management crews and sending out alerts to travelers through a variety of ways.

Adaptive Traffic Signals

Well-coordinated traffic signals can increase safety on Maricopa County’s roadways as well as improve travel efficiency, reduce travel delays and save motorists time and fuel. Adaptive signal control technology systems allow traffic signals to respond to real-time traffic demand. Read more about Adaptive Traffic Signal Control Technology.

Traveler Information

Traffic information obtained through the TMC is relayed to travelers via the Arizona 511 Travel Information hotline, dynamic message boards, emails, text alerts, social media, and eight travel information kiosks located around the county.

Incident & Emergency Management

MCDOT's Regional Emergency Action Coordination Team (REACT) responds to traffic incidents to provide traffic control, secure the incident scene and protect emergency workers.

Corridor Management

The TMC utilizes a signal management system along the Bell Road corridor. This system uses data and knowledge-based algorithms to time the signal lights to maximize traffic flow and thus decrease commute times along Bell Road. Travelers can receive real-time travel times on dynamic message boards placed along the corridor.


AZTech is a regional traffic management partnership in the Phoenix Metropolitan Area that includes all major governmental transportation agencies and some local public safety agencies. The partnership, led by the Maricopa County Department of Transportation (MCDOT) and the Arizona Department of Transportation (ADOT) guides the application of ITS technologies for managing regional traffic by working with member committees. The goal is to achieve more efficient mobility, less congestion, and a higher level of safety for travelers throughout the metropolitan area.
