Navigation Server Route Guidance via Modified Flow Speed Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face challenges in providing flexible and efficient route recommendations to navigation devices, often requiring abrupt maneuvers to follow directly transmitted recommended routes, which can lead to suboptimal routing and increased traffic congestion.
Innovation Solution
A method and system where a server modifies attribute data for navigable segments to make certain routes more favorable, allowing navigation devices to gradually converge onto a recommended route without abrupt changes, by transmitting modified attribute data such as increased flow speed, thereby indirectly communicating a recommended navigable stretch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a server directly transmits recommended routes to navigation devices, then route recommendation efficiency is improved, but navigation devices must perform abrupt maneuvers to follow the recommended route
Solution Approach 1:
The server modifies attribute data parameters (such as flow speed, travel time, or cost) associated with navigable segments to indirectly guide navigation devices toward recommended routes. Instead of directly transmitting route instructions, the server changes the parameters that navigation devices use for their own route determination, allowing devices to naturally converge on recommended paths through their existing routing algorithms without abrupt maneuvers.
2Productivity
If navigation devices follow directly transmitted recommended routes, then route efficiency is improved, but traffic congestion increases due to abrupt maneuvers
Solution Approach 1:
The server modifies attribute data parameters to influence route determination in a way that promotes gradual convergence onto recommended routes. By adjusting parameters like flow speed or travel time estimates for specific navigable segments, the server guides multiple navigation devices toward efficient routes without causing synchronized abrupt maneuvers that would generate traffic congestion.
3Adaptability or versatility
If a server transmits modified attribute data to navigation devices, then route determination flexibility is improved, but data transmission complexity increases
Solution Approach 1:
The server uses the existing attribute data structure that navigation devices already expect and process for their own route determination. By modifying these existing parameters rather than introducing new data formats or communication protocols, the server achieves flexible route guidance while maintaining compatibility with standard navigation device operations, thus avoiding increased transmission complexity.

AI summary
A server 402 determines modified flow speed data for each navigable segment of a recommended navigable stretch. The modified flow speed data is determined so as to make the segment more favourable when a route is determined by a navigation device through the navigable network using the flow speed data. The server transmits the modified flow speed data to a set of one or more navigation devices 400 for use by the or each device at least for the purposes of determining a route through the network of navigable segments. Each navigation device then determines a route to a destination using the modified flow speed data.
