Route Guidance System with Destination Vehicle Counting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional route guide services cannot provide congestion information at the destination location, which is crucial for users planning to visit crowded places, as they only offer route information up to the final destination without considering the number of vehicles already arrived and those expected to arrive.
Innovation Solution
A route guide apparatus that includes a counting unit to determine the number of vehicles already arrived and those expected to arrive at the destination, and a congestion information generating unit to provide real-time congestion information, which can be integrated into the route guide, considering historical data and statistical information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional route guide service provides only route information to destination, then the service is simple and easy to implement, but congestion information at destination cannot be provided
Solution Approach 1:
The patent combines route guide functionality with congestion information provision into a unified service. The server integrates counting unit functions to track arrived and expected vehicles, merging these counting operations with the existing route guidance system to provide comprehensive information without requiring separate independent systems
Solution Approach 2:
The route guide server is enhanced to perform multiple functions: providing route guidance, counting arrived vehicles, estimating expected vehicles, and generating congestion information. This multi-functional approach allows a single system to address both navigation and congestion awareness needs
2Reliability
If real-time congestion information is provided by counting arrived and expected vehicles, then congestion awareness is improved, but information processing complexity increases
Solution Approach 1:
The system performs preliminary counting of arrived vehicles and preliminary estimation of expected vehicles before the user actually needs the congestion information. By continuously tracking vehicle arrivals and route requests in advance, the data is ready when needed, reducing last-minute processing complexity
Solution Approach 2:
The system establishes feedback loops where vehicle arrival data feeds into congestion information generation, which then feeds back to users. The counting unit continuously monitors arrived vehicles and uses this feedback to update congestion status, creating a dynamic information system that adapts to real-time conditions
3Measurement precision
If the system counts number of arrived vehicles and expected vehicles, then congestion information accuracy is improved, but data collection requirements increase
Solution Approach 1:
The route guide terminal devices themselves participate in the data collection process by transmitting their destination information to the server. Each terminal serves as a data source, automatically providing its intended destination without requiring external surveying or manual input, thus enabling precise vehicle counting through self-reporting mechanisms
Solution Approach 2:
The server acts as an intermediary that collects destination information from multiple terminal devices and processes this data to determine arrived and expected vehicle counts. Rather than requiring direct communication between terminals or complex distributed counting, the server mediates data collection and performs centralized counting based on transmitted destination information
Data Source
AI summary
Disclosed herein are a route guide apparatus and a control method thereof. When a route guide to a specific location is requested, congestion information considering the number of vehicles having already arrived at the specific location at the moment that the route guide is requested and the estimated number of vehicles expected to arrive is generated and provided, such that a user requesting the route guide can learn the congestion information on the specific location in advance.
