Templatized 5G Ad-Hoc Network for Dynamic Speed Limit Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the ability to dynamically provide vehicle drivers with real-time, lane-specific speed limit information, leading to potential accidents due to missed speed signs and lack of automatic speed adjustments based on current lane location.
Innovation Solution
A 5G-enabled dynamic ad-hoc network is established between vehicles and roadside devices, using templatized dedicated traffic channels to quickly connect and transmit speed limit information, which is then displayed on the vehicle's speedometer with color-coded alerts, ensuring drivers are aware of appropriate speed ranges for their lane and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional communication systems are used to provide traffic information, then system complexity is reduced, but information transfer rate and real-time capability are insufficient
Solution Approach 1:
The patent changes the communication parameter from traditional cellular networks to 5G wireless communication, enabling much higher data rates and lower latency for real-time traffic information transmission. This parameter change allows the system to achieve high-speed information transfer while the templatized connection approach keeps the implementation complexity manageable.
Solution Approach 2:
The system performs preliminary actions by pre-establishing templatized dedicated traffic channel parameters before actual communication needs arise. This allows for rapid connection setup when traffic information is needed, achieving real-time capability without the complexity of ad-hoc network configuration during critical moments.
2Reliability
If real-time lane-specific speed limit information is provided through 5G ad-hoc network, then traffic safety is improved, but connection establishment time and complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring templatized dedicated traffic channel parameters that can be rapidly deployed when needed. The system prepares connection templates in advance, so when a vehicle needs real-time speed limit information, the connection can be established immediately using the pre-prepared templates, minimizing connection establishment time while maintaining safe communication.
Solution Approach 2:
The system uses copying by creating templatized connection parameters that can be replicated and reused across multiple vehicles and communication scenarios. Instead of creating unique complex connections for each vehicle, the system copies and adapts standardized templates, reducing both connection establishment time and complexity while maintaining the reliability needed for traffic safety.
3Speed
If templatized dedicated traffic channels are used for rapid connection, then connection speed is improved, but channel parameter management complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the channel parameter management into distinct, manageable components. The templatized approach segments parameters into standardized templates that can be independently managed, stored, and deployed. This segmentation allows rapid connection establishment through template selection rather than full parameter negotiation, while the modular structure makes parameter management less complex through organized categorization.
Solution Approach 2:
The system changes parameters from detailed, individual channel configurations to simplified templatized parameter sets. By transforming the parameter management approach from granular control to template-based selection, the system achieves faster connection speeds while reducing the complexity of parameter management through standardized, pre-defined parameter groups.
4Loss of information
If color-coded speed limit alerts are displayed on speedometer, then driver awareness is improved, but display complexity and information processing requirements increase
Solution Approach 1:
The patent directly applies color changes by using color-coded alerts on the speedometer display to communicate speed limit information to drivers. Different colors represent different speed limit zones or compliance statuses, providing immediate visual feedback that enhances driver awareness without requiring complex text or numerical displays. This color-coding system simplifies information perception while maintaining the necessary detail for safe driving.
Solution Approach 2:
The system applies partial action by selectively displaying only the most critical speed limit information in color-coded format, rather than presenting all possible traffic data. This selective display approach enhances driver awareness of the most important information (current speed limit compliance) while keeping the display complexity manageable by omitting less critical details.

AI summary
A method includes receiving over a first dedicated traffic channel, DTCH parameters for a second DTCH from a first information providing device; broadcasting a connect command to a second information providing device to establish the second DTCH between the computing device and the second information providing device in a single communication handshake, the connect command comprising the DTCH parameters; receiving over the second DTCH, an electronic traffic signal associated with an area of a vehicular passageway associated with the second information providing device; determining from the electronic traffic signal, a predetermined value of a vehicular passageway parameter associated with the area; comparing the predetermined value with a current vehicle value of the vehicular passageway parameter; generating a command to display an indication in a vehicle as a result of the comparing; and transmitting the command to a display in the vehicle.
