Traffic Management Latency Prediction for Future Driving Instructions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic management systems face challenges in providing timely and accurate driving instructions due to latency in data transmission and processing, leading to outdated instructions by the time they are received by connected vehicles, which can negatively impact traffic flow and efficiency.
Innovation Solution
A traffic management system that estimates the latency in data transmission and predicts future traffic states to determine driving instructions based on anticipated conditions, ensuring the instructions are relevant when received by vehicles, thereby accounting for delays in data aggregation, processing, and communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the traffic management system processes and transmits driving instructions in real-time, then the instructions are based on current traffic conditions, but the transmission delay causes the instructions to be outdated by the time they are received
Solution Approach 1:
The system performs preliminary actions by predicting future traffic states and determining driving instructions in advance, before the actual future moment arrives. The prediction module forecasts traffic conditions at future timestamps, and the instruction determination module prepares appropriate driving instructions beforehand, so that when the predicted future moment becomes present, the pre-computed instructions are already available and immediately applicable without delay
Solution Approach 2:
The system applies preliminary anti-action by compensating for the anticipated delay through prediction. Instead of reacting to current conditions and suffering the delay, the system proactively predicts what conditions will be at the future reception moment and determines instructions that will be appropriate for those predicted conditions, thereby counteracting the harmful effect of transmission delay before it occurs
2Loss of information
If the system collects and processes data from multiple connected vehicles, then comprehensive traffic state information is obtained, but processing time increases causing greater delay
Solution Approach 1:
The system uses preliminary action by performing prediction and instruction determination based on aggregated data from multiple vehicles before the transmission delay occurs. The prediction module processes the comprehensive traffic state information from multiple connected vehicles and forecasts future conditions, then the instruction determination module prepares driving instructions in advance, ensuring that even though data collection from multiple sources takes time, the processing is completed proactively so results are ready when needed

AI summary
A method of operating a traffic management system comprises receiving data from a vehicle indicating a traffic state, estimating a future time at which the vehicle will receive driving instructions transmitted by the traffic management system, predicting a future traffic state at the estimated future time, determining the driving instructions for the vehicle based on the predicted future traffic state, and transmitting the driving instructions to the vehicle.
