Taxi Terminal Sensor Control for Empty-Car Call Dispatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call dispatch services for taxis result in reduced satisfaction due to continuous dispatch notifications during taxi operations and inefficiencies, and may lead to vacancies upon arrival at destinations.
Innovation Solution
A call dispatch control system and method that utilizes a taxi terminal to send event information based on sensor signals and passenger states, allowing the call server to control dispatches by excluding or including taxis based on their availability and location, ensuring calls are received only when the taxi is empty or about to become empty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the call dispatch service continuously sends calls to taxis, then the call dispatch service coverage is improved, but the taxi operator satisfaction deteriorates due to noise and inefficiency
Solution Approach 1:
The system dynamically adjusts the taxi's call reception status based on real-time sensor data. When sensors detect the taxi is moving or a passenger is present, the system automatically blocks incoming calls. When the taxi is stationary and empty, calls are permitted. This dynamic adaptation resolves the contradiction by making the dispatch service coverage adaptable to the taxi's actual operational state, thereby maintaining service availability while preventing unnecessary notifications that reduce operator satisfaction.
Solution Approach 2:
The system implements feedback loops where sensor information (motion detectors, weight sensors, GPS) continuously monitors taxi status and feeds this data back to the call dispatch control module. This feedback mechanism enables the system to automatically adjust call reception permissions based on real-time conditions, ensuring calls are only received when the taxi is actually available, thus improving operator satisfaction without compromising service coverage.
2Ease of operation
If the taxi receives call dispatch only after arriving at destination, then the taxi operator satisfaction is improved by reducing notifications, but the productivity deteriorates due to vacancy
Solution Approach 1:
The system performs preliminary assessment of taxi availability using sensor data before permitting call dispatch. By detecting when the taxi has arrived at the destination (through motion sensors and GPS), the system proactively prepares to receive new calls immediately upon arrival, rather than waiting for manual input. This preliminary action ensures seamless transition from one trip to the next, maintaining high productivity while keeping notification frequency optimized for operator satisfaction.
Solution Approach 2:
The taxi terminal system automatically monitors its own operational state through integrated sensors and autonomously manages call reception permissions without requiring manual driver intervention. The system self-determines when the taxi is available based on sensor feedback and automatically accepts or blocks calls accordingly, thereby maintaining high utilization rates while minimizing unnecessary notifications that would reduce operator satisfaction.
3Adaptability or versatility
If the call dispatch service does not know the taxi is in operation, then the call dispatch service coverage is maintained, but the measurement precision deteriorates regarding taxi availability status
Solution Approach 1:
The taxi terminal is designed as a multi-functional device that simultaneously handles traditional call dispatch communication and integrated sensor monitoring. By combining GPS tracking, motion detection, weight sensing, and call management into a single universal system, the terminal can precisely determine taxi availability status while maintaining full call dispatch service coverage. This multi-functionality enables the system to know the taxi's operational state without requiring separate monitoring systems.
Solution Approach 2:
The taxi terminal acts as an intermediary between the call dispatch server and the physical taxi environment. It receives sensor data from the taxi's operational environment and translates this information into availability status information that the call dispatch server can understand and act upon. This intermediary function enables precise measurement of taxi availability while maintaining seamless call dispatch service coverage.

AI summary
An embodiment method for providing a call dispatch control service includes receiving, by a call server, event information from a taxi terminal corresponding to an empty car signal indicating that a passenger has exited a vehicle or a driving signal indicating that the passenger has entered the vehicle, receiving, by the call server, a call request from a user terminal, and dispatching, by the call server, a call of the user terminal to the taxi terminal in response to the event information received from the taxi terminal indicating an empty car.
