Wireless Worksite Traffic Control for Adaptive Flagger-Free Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic management at worksites relies heavily on flagmen, which is costly and poses safety risks due to their proximity to moving traffic, while mechanical systems struggle to adapt to changing conditions effectively.
Innovation Solution
A portable traffic management system featuring a wireless interface, mast, support base, and base station that uses sensors and a wireless control device to generate and transmit control signals for traffic control signals, allowing for adaptive management of traffic flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flagmen are used to control traffic, then traffic flow can be managed, but safety deteriorates due to proximity to moving traffic
Solution Approach 1:
The patent replaces human flagmen with an automated mechanical traffic control system consisting of traffic control signals, sensors, and a base station. This substitution eliminates the need for humans to physically position themselves near moving traffic while maintaining effective traffic management through automated signal control.
Solution Approach 2:
The patent introduces traffic control signals as an intermediary between the control system and the traffic flow. These signals act as a mediator that can manage traffic without requiring direct human intervention in the traffic path, thereby protecting operators from exposure to moving vehicles.
2Object-affected harmful factors
If multiple flagmen are deployed at larger worksites, then traffic safety improves, but cost increases significantly
Solution Approach 1:
The automated traffic control system performs multiple functions that would otherwise require multiple flagmen. A single base station with sensors and traffic control signals can simultaneously monitor and control multiple traffic streams, providing comprehensive safety coverage across large worksites without requiring proportional increases in personnel.
Solution Approach 2:
The system incorporates sensors that automatically detect traffic conditions and enable the base station to autonomously control traffic signals without human intervention. This self-service capability allows the system to maintain safety across extensive worksites using minimal human resources, primarily for deployment and monitoring rather than active traffic control.
3Quantity of substance
If mechanical traffic management systems are used, then cost reduces, but adaptability to changing traffic conditions deteriorates
Solution Approach 1:
The patent incorporates sensors that continuously monitor traffic conditions and feed this information back to the base station. This feedback mechanism enables the automated system to detect changes in traffic flow, congestion, or incidents and dynamically adjust traffic control signals accordingly, providing adaptability comparable to human flagmen while maintaining cost efficiency.
