A pedestrian alert system supported on a mobile device such as a smartphone, tablet computer, or a wearable computing device which is employed by a user to engage in various activities, is configured to provide visual, auditory, or haptic alerts when the system uses location sensing and map data to determine the user's proximity to a pedestrian street crossing. The alert attracts the user's attention by having the user perform an explicit action to dismiss the alert before being able to continue with the activities on the device. Operations are suspended for applications rendering content on the device display (e.g., a touch screen), user inputs are disabled, and the display may be blurred, dimmed, obscured, or otherwise deactivated. The pedestrian alert system can take a snapshot of application state prior to suspension so that the applications can gracefully resume operations without disruption once the alert is manually or automatically dismissed.
