Intersection monitoring refers to the supervision of traffic that allows vehicles to pass safely and efficiently through cross traffic. Traditionally, timer systems facilitate the smooth flow of traffic. In the past two decades, however, such outdated systems have been replaced with advanced equipment that make it possible to gather more information from edge level devices. As a result, a much larger volume of traffic can safely and efficiently pass through intersections. To allow for such improvements, several requirements must be met. Read on to learn more about the application requirements for intersection monitoring.

Industrial-Grade Networking Devices

The range of harsh outdoor environment traffic equipment typically requires the use of industrial-grade networking devices. Industrial-grade equipment is durable so that it can function properly even in extreme heat and cold, as well as rain, sleet, and snow. In addition, the equipment can also resist severe vibrations, which pose a challenge for many intersection monitoring systems.

Remote Access, Surveillance Systems, and Real-Time Data Transmission

For optimal efficiency regarding intersection monitoring, it’s essential for the traffic controller to operate and monitor traffic management devices remotely. For example, if the traffic controller receives input statistics from sensors, or other monitoring devices, that an intersection has a backup, they can lengthen green lights to help alleviate traffic. To obtain such data, traffic controllers also require reliable live video surveillance of the intersection. The use of surveillance systems and the presence of real-time data transmission is equally vital to the proper function of intersection monitoring.

Alarms and Warnings

Based on the amount of equipment and complexity of intersection monitoring, it’s essential to have a system in place that notifies personnel of potential issues. Alarms and warnings are key application requirements, as they can send important alerts back to traffic management centers to deal with the problem.

Ability to Combine Data from Different Systems

Intersection monitoring relies on data from various systems to function properly. Since there are multiple different systems involved, it’s essential to have networks that can combine data from several communication mediums. Industrial Ethernet switches allow for this capability, which increases the quantity of connection points for Ethernet-based field equipment and industrial media converters. This allows otherwise incompatible media to connect.

Network Redundancy

Network redundancy refers to when a network infrastructure includes additional or alternate instances of network devices, communication mediums, and equipment. Due to such redundancy, networks can operate despite a transmission path failure. Such redundancy is essential for intersection monitoring because it requires a reliable and efficient network that operates on a 24/7 basis. This allows for communication between equipment and traffic management centers.
