A method of providing a graphical indication of traffic congestion along a stretch of physical road notionally divided by a traffic information provider into one or more road segments is disclosed. The nucleic acid sequence is 2284 nucleotides long and contains an open reading frame from nucleotides 166 to 1956. Additionally, the method allows error messages that occur during the authentication process to be displayed to the user having the look and feel of the first server, despite using the authentication process of the second server. The method includes determining correlation coefficients from the TPMS data and the DDS data by using a correlation function.
