Reference Geocode Generation for Delivery Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current item tracking systems in transportation are passive and often fail to detect delivery errors, such as incorrect addresses, leading to delayed or lost shipments, especially for high-value items, and may inadvertently draw attention to valuable items through special security measures.
Innovation Solution
A system and method that generate a reference geocode for each point address using historical GPS samples during delivery or pickup, allowing real-time comparison with current location data to determine if an item is being delivered to the correct address, using a portable device to notify drivers of potential mis-deliveries and providing a zone of confidence around the reference geocode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive item tracking systems are used, then device complexity is reduced, but delivery accuracy and reliability deteriorate due to inability to detect mis-deliveries
Solution Approach 1:
The system pre-generates reference geocodes for all expected delivery locations before actual deliveries occur. These reference geocodes are stored in a database and used during deliveries for comparison with actual GPS locations, enabling proactive detection of potential mis-deliveries without adding complex real-time analysis capabilities
Solution Approach 2:
The system continuously compares actual GPS location data from delivery vehicles against pre-established reference geocodes and provides immediate feedback when deviations are detected. This feedback mechanism alerts personnel to potential mis-deliveries in real-time, significantly improving delivery accuracy through automated monitoring
2Reliability
If special shipping channels with stringent security measures are used, then reliability of high-value item transport is improved, but object-generated harmful factors increase due to drawing attention to valuable items
Solution Approach 1:
The monitoring system operates autonomously by automatically comparing GPS location data against reference geocodes and generating alerts without requiring manual intervention. This self-service capability provides continuous security monitoring for high-value items while maintaining the appearance of standard shipping procedures, thus protecting items without drawing unnecessary attention
Solution Approach 2:
The system replaces physical security measures and manual monitoring with automated electronic GPS tracking and computer-based geocode comparison. This substitution provides equivalent or superior security reliability while avoiding the visual indicators and procedural anomalies that would draw attention to high-value shipments
3Loss of time
If passive tracking systems are used, then device complexity is reduced, but loss of time increases due to delayed detection of delivery errors
Solution Approach 1:
The system implements real-time feedback by continuously monitoring GPS location data and immediately comparing it against reference geocodes. When a deviation indicating potential mis-delivery is detected, the system generates an instant alert, reducing the time to detect errors from days or weeks to minutes or seconds
Solution Approach 2:
By pre-establishing reference geocodes for all expected delivery locations before deliveries occur, the system eliminates the need for complex real-time analysis or manual verification procedures. This preliminary preparation enables rapid comparison and immediate detection of mis-deliveries, significantly reducing response time
Data Source
AI summary
Systems and methods are provided for generating a reference location data set, such as a reference longitude and latitude point, for each of a plurality of point addresses. A reference location data set can be determined for a point address based on a history of prior geocode samples, such as GPS readings, that have been obtained using a portable computing device during a prior delivery to or pickup from the point address. A location data service collects such geocode samples and processes the samples to generate a reference location data set, such as a reference longitude and latitude and a zone of confidence around the reference longitude and latitude, for each unique point address. To determine whether an item is being delivered to a wrong address, current location data obtained during a delivery can be compared against the reference location data generated by the location data service for the delivery address.
