The disclosure includes a system and method for dynamic vehicle navigation using roadway junction impact. The system includes one or more processors configured to identify a client device location and a destination location, and to determine roadway segments and roadway junctions based on the client device location, destination location, and map data. The system may calculate a travel time for each roadway segment, an impact of traffic on a local roadway junction travel time, an impact of traffic on a remote roadway junction travel time, determine routes between the client device location and the destination location using the determined travel times, and calculate a total travel time for each route based on the travel times. In some instances, the system may determine and provide route guidance for a selected route.
