Navigation Apparatus Car Pool Lane Route Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional navigation apparatuses do not allow users to easily switch between routes using car pool lanes and those not using car pool lanes while driving, limiting flexibility and efficiency in response to changing traffic conditions.
Innovation Solution
A navigation apparatus with a current position detecting unit, input means, route searching unit, display means, and control unit that allows users to promptly switch between routes using and not using car pool lanes based on user input, enabling quick selection of high-efficiency routes according to traffic states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the navigation apparatus performs route search considering car pool lane restrictions, then the route search accuracy is improved, but the operation complexity increases due to requiring passenger number input
Solution Approach 1:
The navigation apparatus performs preliminary route searches for both car pool lane usable and unusable routes before the user makes a selection. This allows the system to prepare multiple route options in advance, so when the user later wants to switch route types, the alternative routes are already calculated and ready for immediate display, eliminating the need for complex real-time recalculations
Solution Approach 2:
The route searching unit is designed to perform multiple functions: it can search for routes with car pool lane restrictions and routes without such restrictions using the same basic search mechanism. By making the search function universal and capable of handling both restricted and unrestricted route scenarios, the system simplifies operation while maintaining accuracy
2Adaptability or versatility
If the navigation apparatus requires user input to switch between car pool lane routes and non-car pool lane routes, then the adaptability is improved, but the response time deteriorates
Solution Approach 1:
The system performs preliminary route searches for both car pool lane usable and unusable routes simultaneously before the user needs to switch. This pre-calculation ensures that when the user requests a route type switch, both alternative routes are already prepared and can be displayed immediately, achieving rapid response while maintaining flexible route selection capability
Solution Approach 2:
The navigation apparatus dynamically switches between displaying car pool lane routes and non-car pool lane routes based on user input. The system maintains readiness for both route types and can quickly transition between them, making the route display dynamic and responsive to changing user preferences or traffic conditions
3Adaptability or versatility
If the navigation apparatus performs dual route searches (with and without car pool lanes), then the adaptability is improved, but the computational load increases
Solution Approach 1:
The navigation apparatus performs preliminary route searches for both car pool lane usable and unusable routes in advance. By calculating both route types beforehand and storing them, the system avoids performing redundant searches when the user wants to switch route preferences, thereby reducing the actual computational load during operation while maintaining high adaptability
Solution Approach 2:
The system merges the route search functionality into a unified process that handles both car pool lane restricted and non-restricted routes. By combining these search operations and managing them through a single control unit, the system reduces overall computational complexity while still providing both route options to the user

AI summary
A navigation apparatus includes a route searching unit 130 for performing both a route search with car pool lanes being made usable between a current position detected by a current position detecting unit and a destination inputted by an input means, and a route search with car pool lanes being made unusable, a display means 2 for displaying either a route which uses a car pool lane or a route which does not use any car pool lane on the basis of route data showing the routes acquired through the route searches by the route searching unit, and a control unit 10 for switching between the route which uses a car pool lane and the route which does not use any car pool lane to display either of them on the display means according to an instruction inputted by the input means.
