Navigation system (1) for a motor vehicle (10), wherein the navigation system (1) is designed to: - to provide an activatable navigation mode for navigating the motor vehicle (10) within an urban area (S1); - to determine a route within the city area (S2) in activated navigation mode, avoiding route sections outside of the city's main roads; and - to control (S3) an output device (2) of the motor vehicle (10) to suggest a specific route in the activated navigation mode; characterized in that - the route sections to be avoided include roads along schools and / or kindergartens within specified time windows.

The invention provides a road system for solving urban traffic jam, which belongs to the technical field of road traffic and comprises a transverse lane and a longitudinal lane, the transverse lane and the longitudinal lane intersect to form a cross-shaped road section, the longitudinal lane is divided into a north lane and a south lane along two sides of the cross-shaped road section, and the transverse lane is divided into a west lane and an east lane along two sides of the cross-shaped road section. The north lane, the south lane, the west lane and the east lane are all two-way traffic lanes, each two-way traffic lane comprises an entrance lane entering the cross-shaped road section and an exit lane leaving the cross-shaped road section, and the entrance lanes are connected to the exit lanes in the same direction through the cross-shaped road section; according to the scheme, based on existing road foundation transformation, large-scale excavation or closed construction is not needed, the engineering amount is small, the period is short, the cost is low, two-way two-lane and above standard urban main roads are compatible, good implementation and universality are achieved, and an economical, efficient and sustainable infrastructure solution is provided for relieving urban traffic congestion.
