An Intersection Database Enhances Blind Pedestrians� Access to Complex Signalized Intersections: Stage 2 Analysis & Database Development
| 项目名称： | An Intersection Database Enhances Blind Pedestrians� Access to Complex Signalized Intersections: Stage 2 Analysis & Database Development |
| 摘要： | This project investigated the effects of providing verbal descriptions of intersections and crosswalks on the performance of street-crossing subtasks by individuals who are totally blind. The intersections included crosswalks that varied widely in geometric and operational characteristics, including the presence or absence of accessibility features. In the no-database condition, participants used their typical street-crossing procedures. In the database-condition, participants additionally listened to database-generated descriptions of the intersections and crosswalks before crossing. The database descriptions had significant positive effects on some subtasks (primarily �crossing� subtasks such as deciding when to cross) and not others (primarily �wayfinding� subtasks such as remaining in the crosswalk) |
