Roadside Event Display for Extending Vehicle Sensor Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Collecting and maintaining vehicle speed and position data, along with other vehicle data, is complex and processing-intensive due to the numerous vehicles on a roadway and their changing speeds and positions.
Innovation Solution
An intelligent transport system that employs on-board vehicular sensors to detect environmental and control data visually or through near-field detection, communicating with a processing system to alert vehicles of upcoming events on the roadway, using display screen devices positioned along the road to provide information to vehicles that cannot detect these events themselves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-board sensor systems are used to detect road events, then vehicle safety is improved, but the detection range is limited to events that are visually detectable by the vehicle
Solution Approach 1:
The patent introduces roadside display screen devices as intermediary elements that receive event data from sensors and display it to vehicles. These display screens act as mediators between the sensor system and vehicles, extending the effective detection range by presenting information about events that are beyond the visual detection capability of on-board sensors alone.
2Measurement precision
If multiple sensors are deployed to monitor all vehicles on the roadway, then detection accuracy is improved, but system complexity and processing requirements increase significantly
Solution Approach 1:
The patent extracts the detection and display functions from a complex multi-vehicle monitoring system and concentrates them in fixed roadside infrastructure. Sensors positioned along the roadway detect events, and display screens present this information to vehicles, eliminating the need for each vehicle to have sophisticated sensor systems or for continuous inter-vehicle communication.
3Loss of information
If display screen devices are positioned along the roadway to show event information, then information delivery to vehicles is improved, but the system requires additional infrastructure components
Solution Approach 1:
The display screen devices are positioned to autonomously present event information to vehicles as they pass by. The system does not require active communication with each vehicle or complex coordination; the displays simply broadcast information that vehicles can passively receive, making the infrastructure self-sufficient in delivering safety information.
Data Source
AI summary
Systems and techniques are described for consuming data in an intelligent transport system. In some implementations, a system includes a display screen device and sensors. The sensors generates data describing sensor observations of a roadway at a first location and provides data describing the observations to the display screen device. The display screen device receives the data and determines an event and a type of the event. The display screen device displays second data indicative of the type of event, the second data being of a format that is consumable by a sensor on a vehicle traversing the roadway towards the first location, the sensor (i) located within a first resolution distance from the display screen device and (ii) located outside a second resolution distance of detecting the event, wherein the second data is used by an on-board processing system of the vehicle to adjust its driving behavior.
