| 摘要： | This report is the third in a series describing the development and evaluation of a software application to facilitate communications for railroad roadway workers using a wireless handheld computer. The current prototype operated on a cell phone integrated with a personal digital assistant (PDA). The roadway worker can perform two types of communication related tasks with the application: request information about train status and territory without assistance from the dispatcher and request track authority. This study documents a field evaluation of the application to identify the safety implications of digital wireless communications on roadway worker safety and performance. It compares performance using traditional voice radio and telephone communications to the use of an application that can display this information in a visual form. |
