摘要： Methods and systems for interpretable user behavior profiling in off-street parking applications. To render user profiles easy to interpret by decision makers, the semi-automatic discovery and tagging of user profiles can be implemented. Transaction data from one or more (and geographically close) off-street parking installations can be implemented. An analysis of spatio-temporal behavioral patterns can be implemented based on representation of any parking episode by a set of heterogeneous features, the use of clustering methods for automatic pattern discovery, an assessment of obtained clusters, semi-automatic identification/tagging of space-temporal patterns, and a user-friendly interpretation of obtained patterns.

摘要： This disclosure provides a method and system for generating one or more available paths from a rider origin location to a rider destination location using a trip planning platform. The generated available paths include, at least in part, a rider-sharing route. According to an exemplary system, the transportation network includes one or more fixed routes of transportation associated with one or more of buses, trains, bikes, walking paths and trams.

摘要： Methods and systems for estimating airport usage demand. Airport parking traffic usage data and flight-time table data can be compiled with respect to an airport (or more than one airport). The airport parking traffic usage data and flight-time table data can be analyzed using an efficient time matching approach (e.g., a time segment matching algorithm). An efficient method to match passengers and flights is introduced. Passenger behavior can be estimated with respect to the airport based on the airport parking traffic usage data and flight-time table data.

摘要： This document discloses a system that selects a path to reach a destination in a transportation network. The system receives information related to a public transportation network with multiple stops. Each stop includes at least one associated link with another stop. Each link represents a mode of transportation between two stops. When the system receives a request for routes between an origin and a destination within the transportation network, it will determine a set of routes between the origin and the destination using an iterative process without reference to a graph representation of the network. The system will select a shortest path that corresponds to the route having the earliest arrival time at the destination. The system will also select an alternative path that corresponds to a route having an arrival time that is no more than a threshold amount later than the earliest arrival time.

摘要： A method for computing a metric for evaluating reliability of a transportation service includes collecting transportation data for at least a part of a transportation network. For at least one of the stops on at least one route of the network, dimensions of the metric for evaluating reliability are computed. The dimensions are selected from: a) a perceived waiting cost, b) a cost of lateness at a final destination, based on a difference between a scheduled arrival time and an actual arrival time; and c) an annoyance cost due to a missed connection at the stop. A representation of at least one of the computed dimensions is generated for at least one of the stops, for at least one of the passengers and is output.

摘要： A method and system are disclosed for learning a demand model and simulation parameters from validation information. Validation information is received from automatic fare collection systems and trips are reconstructed from the validation information. Origins, destinations, and arrival/departure times are estimated from the reconstructed trips. A demand model is then generated from the origins, destinations, and times. Assignment model parameters are then learned from the received validation information and demand model via iterative simulations. Infrastructure changes are made to a simulated transportation network based on the assignment and demand model using the learned parameters. A simulated response of the transportation network to the infrastructure change is then output.

摘要： In a parallel computing method performed by a parallel computing system comprising a plurality of central processing units (CPUs), a main process executes. Tasks are executed in parallel with the main process on CPUs not used in executing the main process. Results of completed tasks are stored in a cache, from which the main process retrieves completed task results when needed. The initiation of task execution is controlled by a priority ranking of tasks based on at least probabilities that task results will be needed by the main process and time limits for executing the tasks. The priority ranking of tasks is from the vantage point of a current execution point in the main process and is updated as the main process executes. An executing task may be pre-empted by a task having higher priority if no idle CPU is available.
