Route Selection via Nearest Side Node for Safe Pickup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users waiting for rides often face difficulties in safely crossing busy streets to reach vehicles on the opposite side, due to traffic, physical barriers, or lack of crosswalks, which can be dangerous and inconvenient.
Innovation Solution
A nearest node or intersection-based routing system that ensures the driver arrives on the same side of the street as the rider by determining the nearest left-hand or right-hand node based on the driving country's conventions, allowing the rider to easily enter the vehicle without crossing the street.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver picks up the rider from the opposite side of the road, then the rider can access the vehicle, but the rider must cross a busy street which is dangerous and inconvenient
Solution Approach 1:
The routing system acts as an intermediary that introduces a intermediate node (intersection or turn point) between the driver's current location and the rider's pickup location. The driver is routed to this intermediate node first, then to the final pickup location, ensuring the vehicle approaches from the correct side of the street without requiring the rider to cross dangerous roads.
Solution Approach 2:
The system performs preliminary routing calculations to determine the optimal approach side before the pickup occurs. By pre-determining the nearest left-hand or right-hand node based on driving conventions, the system ensures the driver arrives at the correct side of the street in advance, eliminating the need for last-minute maneuvers or street crossings by the rider.
2Object-affected harmful factors
If the driver takes a longer route to arrive on the correct side of the street, then the pickup is safer, but the travel time increases
Solution Approach 1:
The routing algorithm changes the parameter of route selection by prioritizing safety-related criteria (approach side correctness) over purely time-efficient paths. The system calculates routes that satisfy the constraint of approaching from the correct side while minimizing time penalty, using parameters such as nearest left-hand/right-hand nodes and driving side conventions to optimize the balance between safety and efficiency.
3Object-affected harmful factors
If the system calculates multiple routes to determine the best pickup side, then the pickup safety is improved, but the system complexity increases
Solution Approach 1:
The routing problem is segmented into distinct components: identifying the rider's location, determining the nearest left-hand or right-hand node based on driving conventions, calculating alternative approaches, and selecting the optimal route. This segmentation allows the system to manage complexity by breaking down the decision-making process into manageable, modular steps rather than attempting to solve all variables simultaneously.

AI summary
Systems and methods are provided for receiving a start location and a destination location, determining a road segment corresponding to the destination location, and identifying a node nearest the road segment corresponding to the destination location, whereby the node corresponds to a nearest left-hand node for a right-hand driving country or a nearest right-hand node for a left-hand driving country. The systems and methods further provide for generating a first route from the start location to the node nearest the road segment corresponding to the destination location, generating a second route from the node nearest the road segment corresponding to the destination location, to the destination location, and combining the first route and the second route to generate a final route. Thus, the final route comprises a route from the start location, through the node nearest the road segment corresponding to the destination location, to the destination location.
