DYNAMIC TRAFFIC SIGNAL OPTIMIZATION USING RECEIVED VEHICLE INFORMATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17542469 titled 'DYNAMIC TRAFFIC SIGNAL OPTIMIZATION USING RECEIVED VEHICLE INFORMATION
Simplified Explanation
The patent application describes a system for optimizing traffic signal control based on the wait time of incoming lanes. Here are the key points:
- The system identifies a set of lanes near a traffic signal that can receive a go-signal.
- It calculates a prioritized overall wait time for each lane.
- The system selects lanes to receive the go-signal based on their prioritized wait time.
- It calculates the amount of time needed for the go-signal based on the number of vehicles in the selected lanes.
- The go-signal is presented to the selected lanes, including non-conflicting lanes.
- The system collects metrics, such as vehicle throughput, to determine the time allocation for the next go-signal iteration.
- It updates parameters for the prioritized wait time and initiates the next iteration of the traffic signal.
Potential applications of this technology:
- Traffic management systems in cities and urban areas.
- Intelligent transportation systems for highways and major roadways.
- Intersection control systems to optimize traffic flow.
Problems solved by this technology:
- Inefficient traffic signal control leading to congestion and delays.
- Lack of coordination between traffic signals causing traffic bottlenecks.
- Inability to adapt traffic signal timing based on real-time traffic conditions.
Benefits of this technology:
- Improved traffic flow and reduced congestion.
- Reduced travel times and delays for drivers.
- Enhanced safety at intersections.
- More efficient use of road infrastructure.
- Potential for integration with smart city initiatives.
Original Abstract Submitted
A set of incoming lanes are identified within a pre-determined proximity of a traffic signal as candidate lanes to receive a go-signal from the traffic signal. A prioritized overall lane wait time is calculated for each incoming lane. Selected lanes receive the go-signal in the current iteration, based on the prioritized overall lane wait time. An amount of time to allocate to the go-signal is calculated, based on the number of vehicles to flush from the selected lanes. The go-signal is presented to the selected lanes for the allocated time, including non-conflicting lanes. A set of metrics are collected including throughput of vehicles leaving the pre-determined proximity of the traffic signal. Based on the metrics, a time allocation is determined for the next iteration of the go-signal, parameters are updated for the prioritized overall lane wait time, and the next iteration of the traffic signal is initiated.
