Traffic Management System with Remote Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic management systems lack the capability for remote and local monitoring and control of groups of mobile traffic lights, particularly in demand-based sequencing, and do not allow for real-time programming and monitoring over the Internet.
Innovation Solution
A real-time traffic management system comprising a main light controller module with a master control unit server software, network operations control module, and network watcher application, which communicates with coordinating light controller modules, uses cameras for vehicle demand detection, GPS for synchronization, and light sensors for ambient lighting adjustments, enabling remote monitoring and control of traffic signals through a network operations center.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If remote monitoring and control of mobile traffic lights is implemented, then traffic management efficiency is improved, but system complexity increases
Solution Approach 1:
The system is divided into separate functional modules: a main light controller module for local control, coordinating light controller modules for synchronization, a network operations center for remote monitoring, and a network watcher for system monitoring. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while enabling remote management capabilities.
Solution Approach 2:
A network communications infrastructure acts as an intermediary between the field-deployed traffic light controllers and the remote network operations center. This intermediary enables remote monitoring and control without requiring direct physical connection to each traffic light, simplifying the system architecture while maintaining productivity.
2Speed
If real-time monitoring and control capabilities are added, then response time to traffic conditions is improved, but device complexity increases
Solution Approach 1:
The system incorporates feedback mechanisms where the network watcher continuously monitors system performance and traffic conditions, and the main light controller receives real-time commands from the network operations center. This feedback loop enables rapid response to changing traffic conditions while distributing intelligence throughout the system, reducing the complexity burden on any single device.
Solution Approach 2:
The system performs preliminary actions by pre-configuring traffic light sequences and monitoring thresholds, allowing automatic responses to common traffic conditions without requiring real-time complex decision-making. This reduces response time for routine situations while keeping device complexity manageable.
3Reliability
If multiple communication radios are used for coordination, then communication reliability is improved, but device complexity increases
Solution Approach 1:
Different communication radios are assigned different functions: some radios handle coordination with nearby traffic lights while others handle communication with the network operations center. This local quality approach ensures reliable communication for each specific purpose while organizing complexity in a manageable way.
Solution Approach 2:
The communication system is segmented into multiple independent radio channels, each handling specific communication tasks. This segmentation improves reliability by ensuring that if one channel fails, other channels can maintain communication, while keeping each individual radio channel relatively simple.

AI summary
A real-time traffic management system comprising a main light controller module configured to monitor and control functionality of one or more traffic lights, a master control unit server software application, a network operations control module, and a network watcher application program. The main light controller module communicates with one or more coordinating light controller modules, onsite personnel, and a network operations center. The main light controller uses a camera that detects instances of vehicle demand and provides live images for situational awareness. The main light controller module comprises a global positioning satellite receiver and a light sensor for monitoring ambient lighting conditions. The network watcher application program continuously scans incoming data, monitors performance of all components in the system, and issues alerts and alarms to notify personnel of events or conditions outside of established tolerances.
