Intelligent Mobility for Connected Cities

Intelligent mobility does not begin only with digital platforms or control centers. It begins with the urban infrastructure that allows a city to organize, measure, and manage traffic flow more effectively.

In Nogales, TSN participated in a comprehensive intelligent mobility project that included the modernization of 25 intersections. The scope combined road infrastructure, traffic engineering, traffic signal controllers, vehicle signals, pedestrian signals, push buttons, vehicle counting systems, civil works, structures, a traffic management system, and a control center.

The project was not simply about replacing traffic signals. It was a complete urban intervention, where each intersection had to operate correctly in the field while also integrating into a broader traffic management network. That is an important difference between a conventional installation and a smart city solution: the elements do not operate in isolation; they work as part of a system.

Each intersection required analysis, preparation, ducting, structures, cabling, controllers, pedestrian elements, operational configuration, and on-site validation. The scale of the project required coordination between engineering, civil works, installation, technology, and operations.

Civil works were a fundamental part of the deployment. A reliable traffic signal network depends on the infrastructure that supports it: foundations, conduits, handholes, poles, cabling, cabinets, power service, and physical elements capable of supporting daily city operation. Without proper field execution, technology loses reliability.

Traffic engineering was also essential. Each intersection has different conditions: vehicle flows, peak-hour demand, pedestrian crossings, conflicting movements, commercial areas, secondary accesses, and urban dynamics that cannot be solved with a generic configuration. For that reason, the technical design had to respond to the real behavior of the city.

The management system helped create a more organized and supervisable operation. Instead of relying only on isolated equipment at each intersection, the solution integrated capabilities to manage and monitor the network from a control center. This enables more efficient management, better operational follow-up, and a technology base for future expansions.

Vehicle counting systems added an important layer of information. Modern mobility should not operate only through perception. It needs data to understand flows, identify patterns, and make better decisions regarding adjustments, maintenance, and network growth.

The integration of pedestrian signals and push buttons also strengthened urban safety. An intelligent mobility strategy cannot focus only on vehicles. It must also consider pedestrians, safe crossings, waiting times, accessibility, and coexistence between different users of the public road network.

For TSN, this project represents a clear example of full execution capability: engineering, civil works, traffic technology, integration, configuration, commissioning, and centralized operation. Few mobility solutions can be solved from a single discipline. These projects require coordination between field teams, engineering, software, infrastructure, and operations.

The modernization of 25 intersections made it possible to build a more functional, visible, and manageable traffic signal network. Beyond the equipment, the value of the project was in turning a group of urban intersections into connected infrastructure for traffic management.

Today, cities face increasing pressure on their road networks: urban growth, more vehicles, higher pedestrian demand, and the need to make decisions based on data. Intelligent mobility projects are therefore an important foundation for any connected city strategy.

A well-designed intersection reduces friction. A well-integrated network improves the operation of the entire city.

TSN’s experience in this project reflects exactly that: the ability to execute intelligent mobility solutions where engineering, infrastructure, and technology work as one system.
