Intelligent Redirection of Vehicular Traffic Due to Congestion and Real-Time Performance Metrics
First Claim
1. A system for intelligent redirection of vehicular traffic comprising:
- a database containing various types of information that can influence the flow of track on a roadway, the information including specific information about each of selected number of roadways, real time weather, traffic and construction conditions on a selected roadway and a general configuration of roadways in the approximate vicinity of a particular roadway;
a monitor positioned at a location along an identified roadway for tracking the average vehicle speed of vehicles that pass said monitor;
a decision module capable of determining alternate roadway routes when there is congestion on a roadway;
an execution module generating a specific procedure for implementing a solution to congestion on the particular roadway that has the congestion; and
a switching mechanism in a piece of roadway equipment for changing information convey be such equipment.

Abstract
An automated traffic control system provides real time alternative traffic flow solutions to address traffic congestion on a roadway. A process will pick routes to scan for real-time statistics on the traffic conditions and calculate an average vehicle speed (AVS) for that route, road, highway, etc. If the AVS drops below a historical threshold, a decision matrix is created, whereby all the real-time data is compared with historical data and provides an ideal or best alternative route for “route X”. The operator is provided this information within seconds and is allowed to make a decision to “accept pr decline” the proposed changes in routes. If the proposed changes are accepted, the changes begin to occur automatically such as but not limited to updating electronic signage, changing traffic control signals (all green to keep traffic moving), moving electronic barriers, etc.

8. A monitor device positioned at a location along an identified roadway for intelligent redirection of vehicular traffic in response to roadway congestion comprising:
-
an interface to communicate with a central traffic control system database, the database containing various types of information that can influence the flow of track on a roadway, the information including specific information about each of selected number of roadways, real time weather, traffic and construction conditions on a selected roadway and a general configuration of roadways in the approximate vicinity of a particular roadway;
at least one input receiver to gather information transmitted from roadway sensors;
a software module to determine average vehicle speed of vehicles traveling on the roadway;
a decision matrix to calculate one or more alternate routes when congestion is detected on the roadway; and
instruction sets for implementing alternative traffic routes calculated by said decision matrix. - View Dependent Claims (9, 10)

11. A method for intelligent redirection of vehicular traffic in response to roadway congestion comprising the steps of:
-
monitoring vehicle speed of vehicles traveling on a roadway and passing a detection device positioned on the roadway;
calculating average vehicle speed of vehicles traveling on the roadway;
comparing the calculated average vehicle speed with a previously defined threshold speed;
retrieving roadway characteristics information and information about conditions on the roadway from a central database when the calculated average vehicle speed is below the threshold speed;
automatically generating an action plan to reduce congestion on the roadway based on roadway characteristics and roadway conditions. - View Dependent Claims (12, 13, 14, 15, 16)
