摘要： In a mobile navigation system, it is possible to judge as to whether or not either a traffic jam region or a traffic restriction region is reduced until a moving object reaches this traffic jam region, or traffic restriction region. The mobile navigation system comprises present position detecting means, map information storage means, route searching means, and traffic information receiving means. Further, the navigation system comprises specific region judging means for judging as to whether or not a traffic jam or restriction region is present within the route searched by the route searching means; arrival time calculating means for calculating time required such that the moving object reaches the traffic jam or restriction region; decreasing time detecting means for detecting time during which the traffic jam or restriction region is decreased based upon the traffic jam or restriction information received by the traffic information receiving means; and re-searching control means for causing the route searching means to re-search the route in accordance with a relationship between the output from the decreasing time detecting means and the output from the arrival time calculating means when the specific region judging means judges that the traffic jam or restriction region is present.

摘要： A traffic information display unit having a road type associated traffic information display mode control unit for altering the display mode of a traffic information representation in accordance with the type of a road associated with the traffic information. Alternatively, it may have a traffic information additional symbol adding unit for adding a traffic information additional symbol indicating the direction of a road associated with an accident/regulation information. Those make it possible to solve conventional problems in that a driver must manipulate a switch each time he wishes to distinguish the traffic information representation of an expressway from that of a local road, or that he cannot recognize lane in which the accident/regulation takes place because the traffic information representation of the accident/regulation information was a simple symbol on the road without showing the direction.
摘要翻译：一种交通信息显示单元，其具有道路型相关联的交通信息显示模式控制单元，用于根据与交通信息相关联的道路的类型改变交通信息表示的显示模式。或者，其可以具有用于添加指示与事故/规则信息相关联的道路的方向的交通信息附加符号的交通信息附加符号添加单元。这些可以解决常规问题，因为驾驶员每次想要区分高速公路的交通信息表示与当地道路的交通信息表示时，都必须操纵开关，或者他不能识别发生事故/调节的车道因为事故/规章信息的交通信息表示是道路上的简单符号，没有显示方向。
