Navigation Module Speed Guidance for Green Wave Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic management systems are reactive and fail to optimize individual vehicle movement effectively, leading to traffic congestion, as they require drivers to maintain a constant speed to follow a 'green wave' system, which is impractical in varying traffic conditions.
Innovation Solution
A computer-implemented method using a navigation module onboard vehicles to obtain geolocation data, retrieve traffic light operational information, and calculate an optimal speed to arrive at the next green phase, while considering speed limits and historical data, and output this information to the driver via a user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a green wave traffic light system is implemented, then traffic flow optimization is improved, but driver adaptability to varying traffic conditions deteriorates
Solution Approach 1:
The system provides continuous feedback to the driver about the optimal speed needed to reach the next green light, allowing the driver to adjust their speed dynamically based on real-time traffic conditions while maintaining the green wave advantage
Solution Approach 2:
The navigation module automatically calculates and provides speed guidance based on traffic light operational information, freeing the driver from manual speed control calculations while still maintaining adaptability to traffic conditions
2Productivity
If drivers maintain a constant optimal speed to follow green wave, then traffic congestion is reduced, but ease of operation deteriorates
Solution Approach 1:
The navigation module performs the complex calculation of optimal speed automatically, eliminating the burden of manual speed control from the driver while still achieving the traffic optimization benefits
Solution Approach 2:
The system provides continuous speed guidance feedback to the driver, making it easier to maintain optimal speed by displaying the target speed rather than requiring the driver to calculate and maintain it manually
3Loss of time
If traffic light operational information is provided to drivers, then travel time optimization is improved, but device complexity increases
Solution Approach 1:
The navigation module performs multiple functions including geolocalization, traffic light detection, operational information retrieval, and speed calculation, consolidating what would otherwise be separate systems into a single integrated device
Solution Approach 2:
The navigation module acts as an intermediary between the traffic light system and the driver, automatically processing operational information and translating it into actionable speed guidance without requiring direct driver involvement

AI summary
A computer-implemented method for providing traffic information via a navigation module onboard a moving vehicle, comprising the steps of: obtaining geolocalization data of the vehicle; identifying the closest traffic light ahead the vehicle; retrieving, from a remote traffic light server, operational information on the identified closest traffic light; processing the operational information to determine an optimal speed at which the vehicle should move to arrive at the closest traffic light when it is at green phase; and outputting the optimal speed via a user interface of the navigation module.
