Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles approaching intersections often experience poor safety due to sudden stops or accelerations caused by traffic signals or reckless behavior, leading to potential traffic accidents.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers react to traffic signals or reckless behavior at intersections by suddenly stopping or braking, then the vehicle can respond to immediate hazards, but the safety of the vehicle is poor due to these sudden maneuvers and potential traffic accidents
Solution Approach 1:
The system performs preliminary calculations of predicted time to intersection and optimal vehicle speed before the vehicle actually reaches the intersection. By computing these values in advance based on current traffic signal states and vehicle parameters, the system enables smooth, pre-planned speed adjustments rather than reactive sudden braking or acceleration, thus improving both safety and driving comfort
Solution Approach 2:
The system cushions against potential hazards by calculating safe speed ranges before the vehicle enters the intersection zone. By determining the optimal vehicle speed in advance that accounts for traffic signal timing and distance to intersection, the system prevents dangerous situations from arising rather than reacting to them, thereby maintaining both safety and operational smoothness
2Reliability
If the system calculates predicted time and optimal vehicle speed in advance, then unnecessary acceleration or braking is prevented, but the device complexity increases with multiple sensing and calculation units
Solution Approach 1:
The system employs a multi-functional integrated approach where the intersection condition sensing unit, intersection pre-entry condition calculation unit, and intersection pre-entry vehicle speed indication unit work together as a cohesive system. The calculation unit performs multiple functions including computing predicted time to intersection, determining optimal vehicle speed, and assessing current condition data, thereby reducing the need for separate dedicated components for each function
Solution Approach 2:
The system utilizes the vehicle's existing motion parameters (current vehicle speed, current vehicle acceleration) and standard traffic signal information to perform its calculations, rather than requiring entirely new sensing mechanisms. By leveraging already-available data and vehicle characteristics, the system reduces the complexity of additional hardware needed while still achieving comprehensive intersection safety guidance

AI summary
Disclosed are herein an apparatus of guiding safe driving at intersections and a method of guiding safe driving using the same. The driving guiding apparatus at intersections includes an intersection condition sensing unit installed at one side of a vehicle and sensing the current conditions around an intersection, an intersection pre-entry condition calculation unit installed at the other side of the vehicle and calculating in advance current condition data before the vehicle enters the intersection based on current condition data corresponding to the current conditions around the intersection sensed by the intersection condition sensing unit, and an intersection pre-entry vehicle speed indication unit installed at the other side of the vehicle and indicating a reference vehicle speed, corresponding to the current condition data calculated by the intersection pre-entry condition calculation unit, before the vehicle enters the intersection.
