Route planning is an important tool to reach points of interest. The current technology offers options for public transportation and pedestrians on the road and sidewalks, respectively. However, for people who use electric powered wheelchairs (EPW) as their primary means of mobility, the level of accessibility and EPW battery consumption are important during route planning. This paper introduces the concept of an accessible route navigation application to reduce EPW battery consumption. The application, called eNav, uses five layers of information including OpenStreetMaps (OSM), airborne laser scanner (ALS), Point-of-Interests (POIs), public transportation, and crowdsourcing. eNav collects these layers of information to provide the shortest, most accessible, and most comfortable routes that consume the least amount of EPW battery. Additionally, the paper presents the Mobility Enhancement roBot (MEBot), a legged-wheeled power wheelchair, to drive over architectural barriers and less accessible environments. The paper proposes the use of MEBot as a sixth layer of information to inform eNav and road authorities about sidewalk/route conditions, to improve road accessibility, and to provide an energy efficient route planning for non-MEBot users.
路线规划是到达目的地的重要工具。当前技术分别为公共交通以及道路和人行道上的行人提供了选择。然而，对于以电动轮椅（EPW）作为主要出行方式的人来说，可达性水平和EPW电池消耗在路线规划过程中很重要。本文介绍了一种可降低EPW电池消耗的无障碍路线导航应用程序的概念。该应用程序名为eNav，使用包括开放街道地图（OSM）、机载激光扫描仪（ALS）、兴趣点（POI）、公共交通和众包在内的五层信息。eNav收集这些信息层，以提供最短、最无障碍且最舒适的路线，同时消耗最少的EPW电池电量。此外，本文还介绍了移动增强机器人（MEBot），一种轮腿式电动轮椅，用于跨越建筑障碍和可达性较差的环境。本文建议将MEBot用作第六层信息，以便向eNav和道路管理部门通报人行道/路线状况，改善道路可达性，并为非MEBot用户提供节能的路线规划。
