Abstract: Users are matched for ridesharing based on where they are from (origin), where they are going (destination), when they are traveling (time), and how often (frequency). Other commuting preferences may also be considered. Geographic matching is based on cross-streets rather than exact street addresses. Locations are geocoded for latitude and longitude. The other users stored in the database are matched with the user by comparing the user's data with the other user's data stored in a database. The user is presented with alias information regarding the matched users in the database for ridesharing. The order in which the matched users are presented may be weighed towards distance or time. Along with the alias information, ratings of these matched users can be displayed. The rating of a user is based on the past impressions of the rated user by other users.
