Abstract: A device receives re-routing event data identifying a deviation from a proposed route at a particular location. The device determines, based on the re-routing event data, whether the deviation from the proposed route is a problem deviation or a planned deviation, and associates, based on determining that the deviation from the proposed route is a problem deviation, the particular location with an problematic location tag. The device determines that a route, corresponding to a request for routing information received from a navigation device, includes the particular location, and determines, based on a user profile and the problematic location tag, a particular alert level, of a plurality of alert levels, to associate with the particular location. The device detects a proximity of the navigation device to the particular location, and causes a particular alert corresponding to the particular alert level to be provided via the navigation device.

Abstract: A device can determine route information associated with a route of a vehicle. The device can identify, based on the route information, feature data associated with the route of the vehicle. The device can determine, based on the feature data, notification information associated with a feature on the route of the vehicle. The feature can include at least one of: a passing zone on the route of the vehicle, a school zone on the route of the vehicle, a potential roadway hazard on the route of the vehicle, a segment of the route with a speed limit that is different from a speed limit of another segment of the route, or a segment of the route with a number of lanes that is different from a speed limit of another segment of the route. The device can provide the notification information associated with the feature.

Abstract: A device can obtain geographic map metadata associated with a set of locations. The device can generate a data structure that associates the geographic map metadata for each location, of the set of locations. The device can receive, from a user device, a request for a set of navigational directions to a first location with multiple entrances, where the first location is one of the set of locations. The request can include information identifying the first location and information identifying a current location of the user device. The device can select an entrance, of the multiple entrances associated with the first location based on the request. The device can determine the set of navigational directions using geographic map metadata associated with the first location. The device can provide the set of navigational directions to the user device to direct the user device to the selected entrance.

Abstract: A device can receive a data model that has been trained on base map data and summary statistics data associated with a first geographic region. The device can obtain additional base map data associated with a second geographic region and additional summary statistics data for a set of junctions within the second geographic region. The device can determine traffic control mechanisms associated with the set of junctions by providing the additional base map data and the additional summary statistics data as input for the data model. The device can generate, using output of the data model, a base map that includes information indicating whether the set of junctions include traffic control mechanisms. The device can, after generating the base map, perform one or more actions associated with improving vehicle navigation or traffic management.
