The results should be seen as an indication of the types of errors that can be encountered, as much as a pronouncement on the probability of success. The Profile does not specify algorithms for composing or decoding the message. Location must be inferred at the receiving end using only the information provided. Furthermore, the profile does not specify the municipality or jurisdiction in which the names occur. A matching name could be found in another area.
Results are therefore dependent on the geographic extent of the test area.
Name Matching Problems Name matching works well only if databases are accurate. The first problem with the data is the large proportion of blank name fields. However, this relies on the destination database also having a populated field for those cross-streets. It could be argued that most of the unnamed streets are remote ranch roads and private tracks, which are irrelevant to ITS needs. Freeway ramps on which many highway incidents are located are typically unnamed.
