Public Transport Access Validation Using Pre-Validation and UWB Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access validation methods for public transport vehicles do not account for users who change their minds at the last moment, leading to unnecessary access validation and account decrements.
Innovation Solution
A method that includes pre-validation of access requests, followed by location determination using distinct wireless communication modes (Bluetooth for initial accreditation and Ultra-Wide Band for location), and only validates access by decrementing a user's account if they are within the access zone and have pre-validated their request.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If access validation is performed when the user is close to the door using Bluetooth protocol, then the access validation speed is improved, but users who change their mind cannot be accounted for leading to unnecessary access validation
Solution Approach 1:
The system performs pre-validation of the access request before the user reaches the door, checking whether the user has the right to access. This preliminary action allows the system to prepare for validation while still having time to cancel it if the user changes their mind, thus avoiding unnecessary account decrements while maintaining fast validation when users proceed with access.
Solution Approach 2:
The system continuously monitors the user's presence and movement through different zones (approval zone, access zone, near door) and provides feedback by adjusting the validation state. If the user leaves the access zone before reaching the door, the system receives feedback and cancels the validation, preventing unnecessary account decrements while maintaining readiness for fast validation when users proceed.
2Measurement precision
If the system uses distinct wireless communication modes (Bluetooth for accreditation, Ultra-Wide Band for location), then the measurement precision of user location is improved, but the device complexity increases
Solution Approach 1:
The system uses Bluetooth protocol for multiple functions including initial accreditation and basic presence detection, while Ultra-Wide Band is specifically deployed for precise location determination. This multi-functionality approach allows Bluetooth to handle routine tasks and UWB to provide enhanced precision only when needed, reducing overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The system introduces an intermediary layer of zone-based detection using Bluetooth before deploying Ultra-Wide Band for precise location measurement. This intermediary approach allows the system to determine when precise measurement is actually needed (when user is in access zone), reducing UWB usage and overall system complexity while maintaining high precision when required.

Function Achieved in This Case
This approach allows for consideration of users who change their minds, preventing unnecessary access validation and ensuring that only authorized users with valid accounts access the zone, thereby optimizing resource usage and user experience.
Implementation Method 1
at least one location transceiver apt to receive a location signal from the connected device in the access zone distinct from the approval zone
Implementation Method 2
sending an accreditation, from an electronic device of a user to a validation system, according to a Bluetooth protocol

AI summary
Method for validating access, by a user, to an access zone and associated electronic validation systemThe invention relates to a method for validating an access, for a user (10), to an access zone (Z5) of a public transport vehicle (5). The method is implemented by an electronic generation system (15),The method comprises the following successive steps:reception of a request for access (Da) to the access zone, from the connected device (20) in an approval zone,pre-validation of the request for access if the request meets a predetermined condition, anddetermination of a location of the connected device in the access zone (Z5) distinct from the approval zone.The method further comprising, once the location of the connected device has been determined in the access zone and only if the request for access is pre-validated, a validation step for an access to the access zone for the user, by decrementing an account specific to the user.
