Road congestion has been one of the major issues in most metropolises, and thus, it is crucial to detect road congestions effectively and efficiently. Traditional solutions require the deployment of dedicated sensors on the roadside or on the vehicles, which suffer from high installation and maintenance costs and limited coverage. In this paper, we propose an alternative solution by exploiting the sensing ability of mobile phones. However, it is challenging to detect road congestions in a daily-living environment using undedicated mobile phones while guaranteeing energy efficiency. The proposed system only depends on the accelerometer and cellular signal, which have been proven to be energy efficient as compared with other built-in sensors (e.g., GPS). It consists of three interactive modules: (a) an accelerometer-based vehicular movement detection module for detecting the periods when the mobile phone user is traveling by vehicle; (b) a map-matching module relying on the cellular signal for determining the traveled road segment
