Abstract:
1. A map display system comprising: at least one hardware processor that implements: a map information acquiring unit that acquires map information indicating a map to be displayed on a display part; a congestion level acquiring unit that acquires a congestion level for each road section within the map; a route line display determining unit that determines whether a route line is displayed superimposed on any road line, the route line representing a planned travel route, each road line representing a road section within the map; and a display controlling unit that, if the route line is displayed superimposed on any road line, displays, based on the map information, the map including the road line and the route line on the display part, determines whether a width of the route line is larger than a width of the road line, and if the width of the route line is larger than the width of the road line, displays a congestion line at a position by a first off-set distance from the road line on the display part, the congestion line representing the congestion level, the first off-set distance being a distance between the road line and the congestion line by which the route line is not overlapped with the congestion line, if the route line is not displayed superimposed on any road line, displays, based on the map information, the map including the road line on the display part and displays the congestion line at a position by a second off-set distance from the road line on the display part, the second off-set distance being a distance between the road line and the congestion line by which the road line is not overlapped with the congestion line, and if the route line is displayed superimposed on any road line and the width of the route line is not larger than the width of the road line, displaying the congestion line at a position by a second off-set distance from the road line on the display part.
