A method for the provision of location-specific transport information by a computer system, wherein the transport information is stored as data sets in a database of the computer system, - wherein the data sets in each case have a location point or a location area, a temporal beginning of the validity period, and - wherein a query is transmitted by a user computer (30, 31, 32) via a user network to the computer network and the query defines a locally, and, in particular, temporally, limited area (B1, B2) and, if necessary, further criteria as query criteria, which indicate, which transport information the respective user operating the user computer (30, 31, 32) is interested in, and - wherein the computer system upon receipt of a query selects those data sets from the database, the assigned location point or location area of which in each case is located within the locally, and, in particular, temporally, limited area (B1, B2) indicated in the query and which meet the, if need be, predetermined further query criteria of the query, and transmits these data sets as the result of the query to the respective user computer (30, 31, 32), - wherein each query received by the computer system is stored after its processing together with its result and is assigned to the latter, and - wherein upon receipt of a further query (Q'), whose locally limited area (B1, B2), and, if necessary, also further query criteria of which is or are also identical with the locally limited area (B1, B2), if necessary, also with the further query criteria, of an already carried out query, which stored result assigned to the query is transmitted to the user computer (30, 31, 32), characterized in - that a user computer (30, 31, 32) when transmitting a query for the first time receives an identification key assigned to this query, to which a period of validity is assigned, and that during the period of validity of the identification key the query can also be carried out by transmission of the identification key, and - that when transmitting a query for the first time through a user computer (30, 31, 32) the determined result is stored in the user computer (30, 31, 32), and when the same query is transmitted again the point in time of the last transmission of the query by the user computer (30, 31, 32) is assigned to this query or to the identification key assigned to the query, and in the event that the result of the query has not changed since the last transmission of the query, such a message is transmitted to the user computer (30, 31, 32) instead of the result. - wherein the data sets in each case have a location point or a location area, a temporal beginning of the validity period, and - wherein a query is transmitted by a user computer (30, 31, 32) via a user network to the computer network and the query defines a locally, and, in particular, temporally, limited area (B1, B2) and, if necessary, further criteria as query criteria, which indicate, which transport information the respective user operating the user computer (30, 31, 32) is interested in, and - wherein the computer system upon receipt of a query selects those data sets from the database, the assigned location point or location area of which in each case is located within the locally, and, in particular, temporally, limited area (B1, B2) indicated in the query and which meet the, if need be, predetermined further query criteria of the query, and transmits these data sets as the result of the query to the respective user computer (30, 31, 32), - wherein each query received by the computer system is stored after its processing together with its result and is assigned to the latter, and - wherein upon receipt of a further query (Q'), whose locally limited area (B1, B2), and, if necessary, also further query criteria of which is or are also identical with the locally limited area (B1, B2), if necessary, also with the further query criteria, of an already carried out query, which stored result assigned to the query is transmitted to the user computer (30, 31, 32), - that a user computer (30, 31, 32) when transmitting a query for the first time receives an identification key assigned to this query, to which a period of validity is assigned, and that during the period of validity of the identification key the query can also be carried out by transmission of the identification key, and - that when transmitting a query for the first time through a user computer (30, 31, 32) the determined result is stored in the user computer (30, 31, 32), and when the same query is transmitted again the point in time of the last transmission of the query by the user computer (30, 31, 32) is assigned to this query or to the identification key assigned to the query, and in the event that the result of the query has not changed since the last transmission of the query, such a message is transmitted to the user computer (30, 31, 32) instead of the result.
