Yahoo!カーナビ - 広い道を優先案内、渋滞情報

Yahoo!カーナビ - 広い道を優先案内、渋滞情報 is a smartphone car navigation app from Yahoo! JAPAN (LY Corporation). Designed for driving in Japan, its signature idea is favouring wide, easy roads over tight shortcuts, backed by live congestion data.

Routes take into account JARTIC traffic congestion data and road regulations, and you can choose to prioritise ordinary roads or expressways. Before setting off, you see travel time, distance, estimated arrival and highway tolls. Voice guidance, up-to-date maps and congestion display are free. Tricky intersections, highway entrances and junctions appear as realistic illustrations, and service and parking area facilities are listed. The app warns about stop signs and speed cameras, shows parking availability and fuel prices, and marks chain requirements, heavy rain and accidents on the map. Registering your car's width tailors routes to its size. Extras include a drive record that scores safe driving, Android Auto support, congestion forecasts near shopping and leisure spots, voice control, saved parking location, background guidance, route sharing via email or LINE, and a My Garage section for inspection and maintenance records. A paid Plus option adds features such as speed warnings, ten waypoints and ad removal.

Ratings are divided. The average is 2.9 from about 103,000 ratings, with 40% one star and 20% five stars. It has 10,000,000+ installs.
