Location-Based Roadside Traffic Alerts for Timely Local Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in obtaining timely and specific traffic information, as current methods require manual search or radio broadcasts that are laborious and often fail to provide the desired information.
Innovation Solution
A traffic system comprising a traffic control center, roadside devices, and receiving terminal devices that utilize wireless communication and Bluetooth technology to transmit real-time traffic information, including accident and road condition updates, directly to vehicles and electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If users manually search for traffic information through mobile web or radio broadcast, then they can obtain traffic information, but the process is laborious and time-consuming, and the information may not be timely or specific to their needs
Solution Approach 1:
The system enables self-service by having terminal devices automatically receive and process traffic information without requiring manual search or interaction. The terminal device passively receives pushed traffic information from the roadside device, eliminating the need for users to manually query or filter information through mobile web or radio broadcast.
Solution Approach 2:
The system performs preliminary action by pre-positioning traffic information collection and processing capabilities at roadside devices near specific locations. This allows traffic information to be prepared and pushed to users before they need it, rather than requiring users to search for information after arriving at a destination.
2Loss of information
If radio broadcast plays traffic information, then traffic information is transmitted to users, but the information is mixed with other programmes and may not be the specific traffic information users want to know
Solution Approach 1:
The system extracts only the specific traffic information needed by users from the general information stream. The roadside device collects traffic information related to specific locations and pushes only that relevant information to terminal devices, eliminating the need for users to filter through mixed content as in radio broadcasts.
Solution Approach 2:
The system applies local quality by providing customized traffic information tailored to each user's specific location and needs. Different terminal devices receive different traffic information based on their geographic location and preferences, rather than all users receiving the same general broadcast information.
3Loss of information
If users manually filter traffic information by region, then they can find specific region information, but the process is laborious and time-consuming
Solution Approach 1:
The system performs automatic filtering and region-specific information delivery without requiring user intervention. The terminal device automatically receives and displays traffic information for its current location or selected region, eliminating the manual filtering process users would otherwise need to perform.
Solution Approach 2:
The system changes the parameter of information delivery from general broadcast to location-specific targeted delivery. By using geographic location as a key parameter, the system automatically adjusts which traffic information is pushed to each user based on their position, eliminating the need for manual region filtering.

AI summary
A method of generating and prompting traffic information includes receiving traffic accident information transmitted by a traffic control center. An influence range of the traffic accident according to the traffic accident information is determined. Traffic information in the influence range is obtained. The obtained traffic information is transmitted to the at least one receiving terminal device in response to the at least one receiving terminal device appears in a communication range. After the traffic accident information is transmitted by the traffic control center, the roadside device determines the influence range. When the receiving terminal device appears in the communication range, the roadside device transmits the obtained traffic information, for making the receiving terminal device to notice the desired traffic information in time. Time and labor are saved. The traffic information reflects an effect of the traffic accident in time. A roadside device is also provided.
