Claim:
1. A method comprising: receiving a traffic message from a traffic message channel, the traffic message including an identifier for a path; receiving location data from a position sensor; accessing, in response to the traffic message, an initial geometry including one dimensional representation of the path; querying, in response to the traffic message, a geographic database using location data and the identifier for the path received from the traffic message channel; determining an envelope size for a dimension of the path from the traffic message based on the identifier for the path received from the geographic database; calculating using a processor, a supplemental geometry based on the envelope size for the path, wherein the supplemental geometry includes an upstream vector and a downstream vector; calculating an intersection point of the upstream vector and the downstream vector; removing a removed portion of the upstream vector or the downstream vector based on the intersection point; generating, using the processor, a two dimensional representation of the path based on the initial geometry, the supplemental geometry, the removed portion, and the envelope size; and rendering a traffic map including the two dimensional representation of the path based on the initial geometry, the supplemental geometry, and the envelope size.
