The discrete model for incident detection using mobile phones

It is generally agreed that the current automatic incident detection algorithms do not achieve the desirable levels. The widespread adoption of mobile phone use among the motoring public suggests considerable potential for incident reporting through mobile phones. The primary advantages of mobile phones are their low cost compared with the cost of a network-wide sensing system. And they are abundant. In this paper, we first explore an approach to simulate incident detection via mobile phone based on a stochastic modeling of section-wide lane traffic systems, which is the real-time estimation of the incident-induced traffic congestion and then discuss the numerical results.
