Traffic Congestion Prevention System Upstream Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing traffic congestion prevention systems face challenges in effectively managing traffic volume control at target road sections, particularly when traffic volume significantly increases, leading to potential failures in preventing congestion.
Innovation Solution
A traffic-congestion prevention system that calculates a target traffic state at a location different from the target location to prevent congestion, using prediction models and control mechanisms to adjust traffic states and display information for optimal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local traffic volume control is performed at the target road section, then the control system is simple and easy to operate, but when traffic volume markedly increases, sufficient control cannot be performed and traffic congestion cannot be prevented
Solution Approach 1:
The patent transitions from one-dimensional local control at the target location to multi-dimensional control by incorporating upstream locations and multiple traffic state parameters (traffic volume, average speed, inter-vehicle distance). This dimensional expansion enables comprehensive congestion prevention by controlling traffic flow at its source before it reaches the congested section.
Solution Approach 2:
The system performs preliminary control actions at upstream locations before traffic congestion occurs at the target location. By calculating target traffic states for upstream areas and controlling traffic flow in advance, the system prevents congestion from developing rather than reacting to it after it forms.
2Reliability
If traffic state is controlled only at the target location, then the control scope is small and operation is simple, but the control effectiveness is insufficient when traffic volume increases significantly
Solution Approach 1:
The control area is extended from the target location to multiple upstream locations, creating a spatially distributed control network. This multi-location approach allows the system to influence traffic flow over a broader area, ensuring that congestion prevention measures are effective even when traffic volume increases significantly.
3Ease of operation
If local control is performed at the target road section, then implementation is straightforward, but the control capability is insufficient when traffic volume markedly increases
Solution Approach 1:
The system automatically calculates target traffic states for multiple locations and determines appropriate control measures without requiring manual intervention. The automated calculation and decision-making processes maintain ease of operation while significantly improving control capability through comprehensive multi-location management.

AI summary
A traffic-congestion prevention system for preventing traffic congestion at a target location at a target time more certainly is provided. The traffic-congestion prevention system 10 includes a traffic state calculation unit 124 and a display control unit 16. The traffic state calculation unit 124 calculates a target traffic state that is a traffic state to be achieved at a location different from the target location in order to prevent traffic congestion at the target location at the target time. The display control unit 16 controls display means in such a way that the target traffic state at the location is displayed on the display means.
