## Abstract

A navigation method for the visually impaired includes the following steps. After obtaining construction information and/or real-time traffic information, a server can transmit the construction information and/or real-time traffic information according to a geographical location. Each traffic condition information transmission device can receive the construction information and/or the real-time traffic information corresponding to a location thereof and forward the construction information and/or the real-time traffic information. A mobile device can modify a navigation route after receiving the construction information and/or the real-time traffic information transmitted from any traffic information transmission device on the navigation route, and the mobile device can convert the construction information and/or the real-time traffic information into a speech message and convert the modified navigation route into a real-time speech guiding message. Thus, the mobile device can perform navigation effectively to avoid the road section under construction or the road section with abnormal traffic condition.
