Solution Overview

Problem

Current traffic control methods, such as traffic signals, cameras, and alternate routes, are ineffective in reducing traffic congestion on highways due to limited intersection control, human monitoring delays, and budget constraints, leading to persistent traffic issues and increased fuel consumption and air pollution.

Innovation Solution

A system that monitors traffic congestion parameters and adjusts road tariffs in real-time, using sensors and position identification technology to notify motorists of adjusted tolls, influencing their route choices and thereby managing traffic flow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traffic signals are used to control traffic flow, then traffic congestion at intersections can be managed, but they cannot be used to control traffic throughput on highways due to the relatively insignificant number of intersections

Engineering Contradiction:
Improvetraffic flow control effectivenessVSAvoidapplicability to different road types
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The invention changes the control parameter from fixed time-based signal cycles to dynamically adjustable road tariffs based on real-time congestion levels. This allows the system to adapt to varying traffic conditions and apply effective control across different road types including highways, where traditional signals are ineffective.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system transitions from static traffic signal timing to dynamic tariff adjustment based on real-time congestion monitoring. The road tariffs are continuously modified according to current traffic conditions, enabling adaptive control that responds to changing demand patterns on both urban streets and highways.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If traffic cameras and electronic billboards are used to notify motorists of road conditions, then motorists can be informed of traffic problems, but human monitoring delays cause a delay between recognition of a traffic problem and notification to motorists

Engineering Contradiction:
Improvetimeliness of traffic informationVSAvoidresponse time to traffic problems
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system employs automated congestion monitoring and tariff adjustment without human intervention. Sensors continuously monitor traffic conditions and the system automatically adjusts road tariffs and notifies motorists in real-time, eliminating human monitoring delays and enabling immediate response to traffic problems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback loops where congestion sensors provide real-time data to the control system, which automatically adjusts tariffs and notifies motorists. This closed-loop feedback mechanism ensures timely detection and response to traffic conditions without human delay.

Inventive Principle:
Principle #23Feedback

3Productivity

If billboards suggest alternate routes to motorists, then motorists can be directed away from congested areas, but notification of a traffic problem on one route often causes a traffic problem on the suggested alternate route

Engineering Contradiction:
Improvetraffic flow optimizationVSAvoidcongestion transfer to alternate routes
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

Instead of uniformly directing all motorists to a single alternate route, the system applies differentiated road tariffs to specific road segments based on their individual congestion levels. This localized approach distributes traffic flow across multiple routes proportionally, preventing the concentration of traffic on any single alternate route.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system applies partial tariff adjustments to multiple routes simultaneously rather than completely redirecting traffic to one alternate route. This distributes the traffic management action across several routes, preventing excessive congestion on any single alternative path.

Inventive Principle:
Principle #16Partial or excessive action

4Ease of manufacture

If road tariffs are used to fund the construction of parallel traffic routes, then funding for infrastructure can be secured, but commuters are often reluctant to use toll routes when non-toll routes are readily available

Engineering Contradiction:
Improveinfrastructure funding capabilityVSAvoidmotorist acceptance of toll routes
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The system uses dynamic tariff adjustment to make toll routes competitive with free routes in real-time. When congestion occurs on free routes, tariffs are adjusted to encourage motorists to switch to toll routes, ensuring continuous motorist acceptance and utilization based on current traffic conditions rather than fixed pricing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes road tariffs from static funding mechanisms to dynamic pricing tools that respond to congestion levels. This allows the system to optimize both infrastructure funding and motorist behavior by adjusting tariffs to reflect real-time traffic conditions, making toll routes attractive alternatives rather than permanent penalties.

Inventive Principle:
Principle #35Parameter changes

AI summary

A vehicular traffic control server includes monitoring means, tariff adjusting means in communication with the monitoring means, and notifying means in communication with the tariff adjusting means. The monitoring means is configured to monitor at least one traffic congestion parameter of a roadway having a road tariff. The tariff adjusting means is configured to adjust the road tariff in accordance with the monitored traffic congestion parameter. The notifying means is configured to notify at least one motorist of the adjusted road tariff.
