Traffic Information System Segmentation for Type-Specific Speed Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic information systems provide inaccurate representations of traffic conditions by not distinguishing between different types of traffic, such as high occupancy toll lanes or truck/bus lanes, leading to misleading average traffic speed calculations and incorrect information for specific vehicle types.
Innovation Solution
A computer-implemented method and system that calculates traffic speeds for different types of traffic and provides type-specific traffic information by determining average speeds associated with each traffic type and transmitting relevant map data to client devices based on user requests, incorporating traffic sample data and road segment attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If average traffic speed is calculated without distinguishing between different traffic types, then the calculation process is simple, but the traffic information becomes inaccurate and misleading
Solution Approach 1:
The patent segments traffic data by dividing it into different traffic types (e.g., HOV, truck, bus, general traffic) based on vehicle characteristics and lane assignments. This segmentation allows the system to calculate separate average speeds for each traffic type, improving measurement precision while managing complexity through structured categorization.
Solution Approach 2:
The patent applies local quality by providing differentiated traffic information tailored to specific vehicle types and their corresponding lanes. Each traffic type receives customized speed calculations and route recommendations based on its specific characteristics, ensuring accurate information delivery without requiring complete system reconfiguration.
2Loss of information
If traffic information is provided for all traffic types, then information completeness is improved, but bandwidth consumption increases
Solution Approach 1:
The patent extracts and transmits only the specific traffic type information relevant to the requesting user's vehicle category. Instead of sending all traffic data, the system identifies and delivers only the necessary subset, maintaining information completeness for the user while significantly reducing overall bandwidth consumption.
Solution Approach 2:
The patent implements partial action by providing traffic information selectively based on user needs and vehicle type. The system transmits sufficient information for the specific traffic type without unnecessary redundancy, achieving optimal balance between information completeness and resource efficiency.

AI summary
A computer-implemented method for determining traffic conditions includes receiving, by one or more computing devices, one or more requests for traffic condition information from a user, the one or more requests including data indicative of a first location, a second location, and a traffic type; determining, by the one or more computing devices, a first transit route from the first location to the second location, the first transit route including one or more transit areas associated with a first traffic type from a plurality of traffic types; determining, by the one or more computing devices, map data indicative of a first transit time for the first transit route, the first transit time corresponding to a traffic speed associated with the first traffic type; and providing, by the one or more computing devices, the map data to the user in response to the request for traffic condition information.
