Abstract
Being unable to get real-time traffic information ahead makes drivers fail to decelerate before accident happens. Mobile phone locator based road black-spot alarming service system was proposed and developed. Based on mobile phone location data, stopping sight distance model, data smoothing and error correction were presented to integrate traffic safety information. By describing how the mobile phone location information including latitude and longitude data was transformed into plane coordinate, vehicle speed information was available and could be fitted into stopping sight distance model. In the alarming service system, the alarming signal would be sent to drivers judging by the threshold and drivers could take avoiding action as soon as possible. This helps to protect drivers’ personal and property safety. They can decelerate safely before reaching a road accident-prone area or potential accident area.
