摘要： A method comprising determining speed-time cluster application histogram data set for a link segment that comprises a plurality of speed-time cluster application histogram data elements, each speed-time cluster application histogram data element identifying a speed-time cluster and an applicable duration of the speed-time cluster for the link segment throughout a histogram duration, for each speed-time cluster application histogram data element, determining a free-flow speed that is representative of a non-congestion speed indicated by the speed-time cluster, determining a historically normalized free-flow speed for the link segment that is a weighted average of the free-flow speed determined for each speed-time cluster application histogram data element weighted by the applicable duration of the speed-time cluster application histogram data element, and identifying a transit speed of the link segment as being the historically normalized free-flow speed is disclosed.

摘要： An approach is provided for providing adaptive location sampling in mobile devices. The approach involves determining one or more maneuvers from among a plurality of one or more links representing a localized area of a transportation network. Each of the one or more maneuvers is a combination of two or more adjacent links of the one or more links. The approach also involves determining a road length and a speed attribute for each link in said each maneuver. The approach further involves calculating a travel time for said each maneuver based on the road length and the speed attribute of said each link. The approach further involves calculating a sampling interval for the mobile device traveling in the localized area based on the travel time. The mobile device is configured to collect probe data using one or more sensors at the sampling interval while traveling in the localized area.

摘要： The disclosed embodiments relate to prediction of traffic dynamics. A descriptive model is provided that uses historical probe data to create “tidal-like” patterns for the usual dynamics on the road network and creates a framework for taking a future time, e.g. in terms of month, day, time, and suggesting a typical speed for the specified road network link at that specific time. With this model, better predictions for estimated time of arrival will be derived. As opposed to blindly extrapolating from a static model, the disclosed embodiments dynamically adapt to current conditions using real time data to adapt, based on current conditions, the model from which a predicted speed may be determined.

摘要： A method, apparatus, computer program product, and device with various means are disclosed for determining the time it takes to a traverse a transportation structure by enclosing a representation of a transportation structure with a bounding polygon, specifying a plurality of gates which represent legitimate entry or exit points of the transportation structure as one or more edges of the bounding polygon, and computing the travel time for a probe traveling through the bounding polygon via the gates. Computing the probe's travel time comprises generating a location trace of movement of the probe, determining an entry and exit time, and calculating the difference between the exit time and the entry time. Determining the entry and exist time can be done by interpolation. An average of a set of computations can be used to get an average of the time it takes traverse the transportation structure.

摘要翻译： 所公开的实施例涉及预测交通动态。 提供了一种描述性模型，其使用历史探测数据来为道路网络上的通常动力学创建“潮汐样”模式，并创建未来时间的框架，例如， 在月，日，时间方面，并指出在特定时间的指定道路网络链路的典型速度。 有了这个模型，就会得出对预计到达时间的更好预测。 相对于从静态模型盲目地外推，所公开的实施例使用实时数据动态地适应当前条件，以根据当前条件来适应可以从其确定预测速度的模型。

摘要： An approach is provided for classifying probe data into qualitative categories to determine a point of interest. The approach involves processing and/or facilitating a processing of probe data to determine one or more trajectories associated with one or more probes. The approach also involves determining one or more clips of the one or more trajectories associated with one or more locations at which the one or more probes lingered based, at least in part, on at least one space threshold value, at least one time threshold value, or a combination thereof. The approach further involves causing, at least in part, an extraction of one or more probe parameter values from the one or more clips. The approach also involves causing, at least in part, a classification of the one or more probe parameter values into one or more qualitative categories. The approach further involves determining one or more points of interest, one or more characteristics of the one or more points of interest, or a combination thereof associated with the one or more locations based, at least in part, on the one or more qualitative categories.

摘要： An approach is provided for generating trajectory bundles for map data analysis. The approach involves receiving probe data associated with the bounded geographic area. The probe data are collected from sensors of a plurality of devices traveling in the bounded geographic area, and includes probe points indicating a position, a heading, a speed, a time, or a combination thereof. The approach also involves constructing a plurality of trajectories from the probe points to represent respective movement paths of said each of the plurality of devices. The approach further involves computing similarities among a plurality of curves represented by the plurality of trajectories. The approach further involves clustering the plurality of trajectories into trajectory bundles based on the similarities with each bundle representing a possible maneuver within the bounded geographic area. The approach further involves generating a map of the bounded geographic area based on the trajectory bundles.

摘要： Drone space is defined according to a building model and a buffer space. At least one three-dimensional geometry is identified from the building model. The buffer space is calculated from the three-dimensional geometry. Coordinates for a drone air space are defined based on the buffer space. At least one path segment may be identified based on the coordinates for the drone air space, and the coordinates for drone air space are stored in a map database in association with the at least one path segment.
