This paper designs and measures the performance of a roadside unit placement scheme for the vehicular telematics network, aiming at improving connectivity and reducing the disconnection interval for the given number of roadside units, the transmission range, and the overlap ratio on the road network of Jeju city. The placement scheme begins with an initial selection that every intersection is the candidate. For each circle surrounding the candidate position with the radius equal to the transmission range, the number of vehicle reports inside the circle is counted. After ordering the candidates by the count, the placement scheme makes the candidate survive when it is apart from all the other candidates already selected by at least the distance criteria. Performance measurement result obtained using the real-life movement history data in Jeju city shows that about 72.5 % of connectivity can be achieved when the number of roadside units is 1,000 and the transmission range is 300 m, while the disconnection time is mostly kept below 10 seconds.
