Dynamic Bus Route Optimization Using Passenger Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
School bus routes are not efficiently adjusted based on actual passenger embarkation data, leading to unnecessary stops and increased operational costs, especially when passenger ridership is low, as existing methods rely on driver familiarity and fixed routes rather than real-time passenger information.
Innovation Solution
A system utilizing a GPS device and passenger identification cards to read and transmit passenger data, generating a dynamic bus route that only includes stops corresponding to embarked passengers, thereby optimizing route planning and minimizing unnecessary stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed bus route is used based on potential passenger locations, then all passengers can be transported, but unnecessary stops are made increasing time and cost
Solution Approach 1:
The bus route is transformed from a static fixed path to a dynamic route that adjusts in real-time based on actual passenger embarkation data. The GPS device continuously receives passenger information and recalculates the optimal route, allowing the bus to skip stops where no passengers are boarding while ensuring all actual passengers are transported.
Solution Approach 2:
The system implements feedback by using the card reader to detect actual passenger embarkation at each stop, then feeding this information back to the GPS device which adjusts the route accordingly. This closed-loop feedback mechanism ensures the route always reflects current passenger needs, eliminating unnecessary stops while maintaining complete passenger coverage.
2Reliability
If the bus traverses the entire fixed route regardless of passenger presence, then all potential passengers are served, but fuel consumption and operational costs increase
Solution Approach 1:
The bus route dynamically adapts its length and stops based on real-time passenger data. The GPS device calculates the shortest effective route that connects only to stops where actual passengers are embarking, transforming the energy-consuming fixed-route traversal into an optimized dynamic path that minimizes fuel consumption while maintaining service coverage.
Solution Approach 2:
The system changes the route parameters (stops, sequence, length) based on passenger embarkation data. By varying these parameters in real-time according to actual demand, the system optimizes fuel consumption without compromising the ability to serve all passengers who need transportation.
3Productivity
If a substitute driver operates the bus without familiarity with the route and passengers, then the bus can operate when the regular driver is absent, but the driver cannot optimize the route to eliminate empty stops
Solution Approach 1:
The bus system performs self-service by automatically collecting passenger embarkation data through card readers, processing this information through the GPS device, and generating optimized routes without requiring driver knowledge or decision-making. This eliminates the dependency on driver familiarity while maintaining operational continuity and route optimization.
Solution Approach 2:
The system replaces the mechanical dependency on driver knowledge and experience with an automated electronic system. The card reader and GPS device substitute for the driver's cognitive abilities to recognize passengers and optimize routes, enabling substitute drivers to operate the bus effectively without prior familiarity with the route or passengers.
4Reliability
If passenger identification and verification is manual, then driver familiarity with passengers is maintained, but time is lost in verification and driver attention is diverted from safe driving
Solution Approach 1:
The manual verification process is replaced with an automated card reading system. The card reader automatically detects and verifies passenger identification cards, eliminating the need for manual inspection by the driver. This substitution maintains verification accuracy through systematic data reading while dramatically reducing the time required and freeing driver attention for safe operation.
Solution Approach 2:
The passenger verification process becomes self-service through automated card reading. The system automatically reads, validates, and processes passenger information without requiring driver intervention, allowing the driver to focus on driving while the system handles verification independently and efficiently.

AI summary
A method of setting a bus route for a bus includes the step of providing a global positioning system (GPS) device (100) on the bus (12), and reading passenger data corresponding to a passenger. The passenger data is read from a passenger identification card and transmitted to the GPS device (16). The method further includes the step of matching the passenger data with a bus stop (28), and generating a bus route with the GPS device (100) based on the passenger data (34). Only bus stops that match passenger data are included in the bus route (34).
