Systems and methods are provided for determining the status of traffic lights through a mobile device and communicating the status to the user of the device. The mobile device detects its geographical location, direction and elevation. The mobile device also receives information related to traffic lights, such as location and type. The device calculates positional deviation from the device to the traffic light and generates one or more prompts in the form of audible or tactile cues that progressively guide the user to point the device at the traffic light. The mobile device detects the image and color of the traffic light and determines the illumination and sign status of the traffic light. Then the mobile device communicates the traffic light status to the user.
