56. Human Factors Suggestions Advanced Pedestrian Button- Pre-Crossing Current design Locator tone Ambient noise compensation Confirmation that a call has been placed Information about intersection location. “Where am I on the earth?” For example – “SW corner of 6 th and Deakin Street” “What direction did I request to cross?” 4/27/200956Boise, Idaho

57. Human Factors Suggestions What is the intersection geometry? Is there a center Island? Is it an orthogonal crossing? How many lanes are there to cross? Is there special traffic information? Left hand turning traffic? Overall give an expectancy of what type of intersection is it. 4/27/200957Boise, Idaho

58. Human Factors Suggestions Advanced Pedestrian Assistant Provide vibrotactile feedback only to prompt/during the walk phase Dash-dash too far left or dash dot dash too far right i.e. rumble strips Strong vibration when on course, reducing in strength when off course Speech notification of when to cross only after confirmation of correct alignment Speech notification of an approaching curb ramp Inform the user of time/ distance left to cross Warning messages for special cases 4/27/200958Boise, Idaho
