Taxi Information System Real-Time Queue Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Taxi drivers lack real-time information about taxi demand and supply at popular destinations, leading to inefficient route planning and ride acceptance, especially in areas with multiple taxi companies and unfamiliar locations.
Innovation Solution
A system with display devices in taxis showing real-time taxi queue lengths, average load times, and ride requests on a map, using GPS navigation and queue information from sensors and dispatch systems to optimize route selection and ride acceptance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If taxi drivers choose to wait in taxi queues at popular destinations, then they can potentially pick up riders, but they may inadvertently choose queues that are relatively long with little demand, resulting in increased idling time and reduced efficiency
Solution Approach 1:
The system implements real-time feedback by continuously monitoring and displaying queue lengths and demand information at various taxi queues. Drivers receive immediate feedback about the current state of different queues, allowing them to make informed decisions about where to wait, thus avoiding long queues with low demand and reducing idling time
Solution Approach 2:
The system dynamically updates queue information in real-time, allowing drivers to adapt their choices based on current conditions rather than static or outdated information. The display devices show current queue lengths and demand levels, enabling drivers to dynamically select the most efficient queue to join at any given moment
2Productivity
If taxi drivers select general areas to drive to for picking up new fares after dropping off riders, then they can continue operations, but they lack information about which areas are currently busiest and have shortest wait times, leading to inefficient route selection
Solution Approach 1:
The system provides real-time feedback about demand levels and average wait times in different geographic areas through display devices in taxis. This feedback enables drivers to make informed decisions about where to position themselves to maximize pickup opportunities and minimize empty driving time
Solution Approach 2:
The system performs preliminary analysis and aggregation of demand data across different areas before presenting it to drivers. By pre-processing location data, queue lengths, and demand patterns, the system prepares actionable intelligence that guides drivers to high-demand areas before they arrive, optimizing their positioning decisions
3Ease of operation
If dispatching systems use radio systems with verbal instructions from dispatchers, then they can communicate ride request locations, but taxi drivers unfamiliar with the location find it difficult to quickly calculate distance without extensive knowledge of the area streets
Solution Approach 1:
The system replaces the mechanical/radio communication system with electronic display devices that visually present location information. Instead of relying on verbal descriptions that require mental mapping, drivers receive visual displays showing their current location, the ride request location, and distance calculations, eliminating the need for extensive local knowledge
Solution Approach 2:
The display device acts as an intermediary between the dispatch system and the driver. It translates complex location data, street names, and distance calculations into intuitive visual representations that immediately convey the relevant spatial information, bridging the gap between raw data and driver understanding
Data Source
AI summary
A system for displaying information to drivers of taxis in an operating region that has a plurality of popular destinations includes a display device fixed within each taxi. The display device includes a plurality of selectable information screens that are each adapted to display information received by a transceiver of the display device. A dispatch information system is adapted to transmit dispatching data of the operating region to the display devices of each taxi. A queue information device associated with each of the popular destinations is adapted to transmit queue information to the dispatching information system. Preferably at least one of the selectable information screens includes a map of the operating region, which may be separated into different grids each having a queue length aggregate indicator that indicates the average load time of all of the taxi queues of the popular destinations within that grid.
