Dynamic Toll Inspector Dispatch via Proximity Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current toll systems face inefficiencies in tracking and inspecting vehicles for toll violations, as inspectors often receive data from roadside control devices that are not in their immediate vicinity, leading to delayed and inefficient intervention.
Innovation Solution
A method involving at least two roadside control devices and mobile display devices, where the central data processing device determines the closest mobile display device to the vehicle's position, ensuring that control data is sent to the inspector nearest to the vehicle, allowing for dynamic data transmission and efficient tracking and intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If inspectors are assigned to specific roadside control devices, then data transmission is simplified, but inspector mobility and response time are reduced
Solution Approach 1:
The system dynamically assigns mobile display devices to control data records based on real-time proximity calculations. The central data processing facility continuously determines which mobile display device is closest to each detected toll vehicle and transmits data to that device, rather than using static assignments. This dynamic approach allows inspectors to move freely while ensuring data is always sent to the nearest inspector, resolving the contradiction between operational simplicity and response time.
Solution Approach 2:
The central data processing facility acts as an intermediary that receives control data from roadside control devices, calculates which mobile display device is closest to the detected vehicle, and then transmits the data to the appropriate inspector. This intermediary function simplifies the overall process by centralizing the assignment logic while enabling flexible, proximity-based data distribution to multiple mobile inspectors.
2Adaptability or versatility
If multiple mobile display devices are used, then inspector flexibility increases, but data transmission complexity increases
Solution Approach 1:
The central data processing facility serves as an intermediary that manages all communications between roadside control devices and multiple mobile display devices. It receives control data, calculates which mobile device is closest to each detected vehicle, and automatically routes data to the appropriate inspector. This central coordination simplifies the complexity by providing a single point of decision-making rather than requiring direct peer-to-peer communication between multiple devices.
Solution Approach 2:
The system creates copies of control data records and transmits them to multiple mobile display devices as needed. When a toll vehicle is detected, the central facility generates control data records and distributes copies to the relevant mobile inspectors based on proximity calculations, allowing multiple inspectors to access the same information independently without complex inter-device communication.
3Loss of information
If data is transmitted to all mobile display devices, then information completeness is ensured, but communication bandwidth and processing load increase
Solution Approach 1:
The system applies local quality by transmitting control data records only to the specific mobile display device that is closest to each detected toll vehicle, rather than broadcasting to all devices. The central data processing facility calculates proximity and selectively routes data based on local conditions (which inspector is nearest), thereby conserving communication bandwidth while ensuring that the most relevant inspector receives the information.
Solution Approach 2:
The system uses partial action by transmitting control data to only one mobile display device per detected toll vehicle - specifically the closest one - rather than transmitting to all devices. This selective transmission approach provides sufficient information to the most relevant inspector without the excessive bandwidth consumption of universal transmission, achieving the right balance between information completeness and resource efficiency.

AI summary
The present invention relates to a method for tracking toll vehicles in a road toll system, comprising the steps of providing at least two stationary, roadside control devices for detecting at least one license plate of a toll vehicle, detecting a license plate of a toll vehicle by a first of the control devices, transmitting the license plate to a central data processing unit, determining the current vehicle position of the toll vehicle based on the position of the first control device, providing at least two mobile display devices for displaying the license plates and current vehicle positions of detected toll vehicles, transmitting the current position of each mobile display device to the central data processing unit, and determining at least one nearest mobile display device.the transmission and display of the license plate number and vehicle position on at least the nearest mobile display device.
