Train Detection System Using GPS Tracking and Wireless Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many vehicle drivers fail to heed warnings or take proper safety precautions at uncontrolled railroad crossings, leading to a high number of collisions and fatalities due to the lack of traffic control devices at a significant portion of public railroad crossings in the United States.
Innovation Solution
A system comprising a train-tracking module and a vehicle-detection module that uses GPS and wireless communication to determine the location of trains and vehicles, predict potential collisions, and alert operators with audio, visual, or tactile warnings to avoid collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traffic control devices are installed at all public railroad crossings, then safety at railroad crossings is improved, but cost is prohibitively high
Solution Approach 1:
The patent extracts the essential safety function from traditional traffic control devices (gates, lights, signals) and implements it through a minimalistic wireless alert system using mobile phones and text messages. This provides safety functionality without deploying extensive physical infrastructure at all crossings
Solution Approach 2:
The system uses inexpensive, widely available mobile phones as the primary safety device rather than expensive dedicated traffic control equipment. The alert mechanism uses simple text messages instead of complex signaling systems, making the solution cost-effective for deployment at numerous crossings
2Reliability
If tracking modules are installed on all trains, then collision detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The tracking module serves multiple functions: it provides location information for collision detection, enables identification of approaching trains, and supports the wireless alert system. This multi-functionality reduces the need for separate dedicated systems
Solution Approach 2:
The system uses an intermediary server that coordinates communication between train tracking modules and vehicle alert systems. This mediator simplifies the complexity by centralizing the logic for determining when and how to send alerts, rather than requiring direct complex communication protocols between all components

AI summary
Techniques for improving safety at railroad track crossings are described. Example embodiments provide a train detection and collision avoidance system configured to detect potential collisions between vehicles (e.g., cars, trucks, motorcycles) and trains. The system detects potential collisions based on location information obtained by tracking modules installed in or carried by the trains and vehicles. When a potential collision between a vehicle and a train is detected, the train detection system alerts an operator of the vehicle and/or the train, so that the operator can take steps to avoid the collision. The operator may be alerted in various ways, including by audio, visual, or tactile output.
