A route guide system comprising: a map data base storing map data including intersection data and indicator data; a current location detection unit suitable for detecting a current position of an own vehicle as a location of the vehicle; a route search processing unit suitable for searching for a route to a destination based on the location of the vehicle; a route guide point setting processing unit suitable for setting a route guide point at a predetermined point on the searched route before a guide intersection; an intersection counting processing unit adapted: to read the intersection data and the indicator data from the map data base; and to sequentially determine based on the intersection data whether there exist traffic signals ( sg1 to sg3) with respect to each intersection ( cr1 to cr3) from the route guide point to the guide intersection on the searched route; characterized in that; the intersection counting processing unit is further adapted, if there is a traffic signals with respect to an intersection, to determine based on the indicator data whether there exists an indicator on the road to enter before the intersection on a travel lane ( k1 to k10) that is a lane the vehicle is going to travel, the indicator being set or formed on the road; and to calculate the number of intersections ( cr1 to cr3) for which it has been determined that there exist a traffic signal and an indicator; and the route guide system further comprises a voice output processing unit suitable for performing a voice output based on the calculated number of the intersections when the vehicle arrives at the route guide point. a map data base storing map data including intersection data and indicator data; a current location detection unit suitable for detecting a current position of an own vehicle as a location of the vehicle; a route search processing unit suitable for searching for a route to a destination based on the location of the vehicle; a route guide point setting processing unit suitable for setting a route guide point at a predetermined point on the searched route before a guide intersection; an intersection counting processing unit adapted: to read the intersection data and the indicator data from the map data base; and to sequentially determine based on the intersection data whether there exist traffic signals ( sg1 to sg3) with respect to each intersection ( cr1 to cr3) from the route guide point to the guide intersection on the searched route; characterized in that; the intersection counting processing unit is further adapted, if there is a traffic signals with respect to an intersection, to determine based on the indicator data whether there exists an indicator on the road to enter before the intersection on a travel lane ( k1 to k10) that is a lane the vehicle is going to travel, the indicator being set or formed on the road; and to calculate the number of intersections ( cr1 to cr3) for which it has been determined that there exist a traffic signal and an indicator; and to read the intersection data and the indicator data from the map data base; and to sequentially determine based on the intersection data whether there exist traffic signals ( sg1 to sg3) with respect to each intersection ( cr1 to cr3) from the route guide point to the guide intersection on the searched route; characterized in that; the intersection counting processing unit is further adapted, if there is a traffic signals with respect to an intersection, to determine based on the indicator data whether there exists an indicator on the road to enter before the intersection on a travel lane ( k1 to k10) that is a lane the vehicle is going to travel, the indicator being set or formed on the road; and to calculate the number of intersections ( cr1 to cr3) for which it has been determined that there exist a traffic signal and an indicator; and the route guide system further comprises a voice output processing unit suitable for performing a voice output based on the calculated number of the intersections when the vehicle arrives at the route guide point.
