Modelling Taxi Drivers’ Behaviour for the Next Destination Prediction

Abstract

In this paper, we study how to model taxi drivers' behaviour and geographical information for an interesting and challenging task: the next destination prediction in a taxi journey. Predicting the next location is a well studied problem in human mobility, which finds several applications in real-world scenarios, from optimizing the efficiency of electronic dispatching systems to predicting and reducing the traffic jam. This task is normally modeled as a multiclass classification problem, where the goal is to select, among a set of already known locations, the next taxi destination. We present a Recurrent Neural Network (RNN) approach that models the taxi drivers' behaviour and encodes the semantics of visited locations by using geographical information from Location-Based Social Networks (LBSNs). In particular, RNNs are trained to predict the exact coordinates of the next destination, overcoming the problem of producing, in output, a limited set of locations, seen during the training phase. The proposed approach was tested on the ECML/PKDD Discovery Challenge 2015 dataset -based on the city of Porto -, obtaining better results with respect to the competition winner, whilst using less information, and on Manhattan and San Francisco datasets. arXiv:1807.08173v2 [cs.AI] 8 Jan 2019 5 www.foursquare.com 6 https://www.kaggle.com/c/pkdd-15-predict-taxi-service-trajectory-i

Trajectory-prediction based relay scheme for time-sensitive data communication in VANETs

“…In order to reduce the impact of resource mobility on vehicle cloud performance, a novel solution based on Artificial Neural Network (ANN) mobility prediction model to predict future trajectory is proposed in [16]. The authors utilized the performance of the vehicle cloud to reduce the impact of sudden changes in vehicle position based on the ANN mobility prediction model.…”

“…But the predicted limit value fluctuates too much and the accuracy fluctuates greatly. In [15][16], the work of mobility prediction in Mobile Ad-hoc Network(MANET) is discussed. Although more and more researchers focus on vehicle mobility prediction, few of them adopt machine learning to predict vehicle mobility.…”

Dynamic Update and Monitoring of AOI Entrance via Spatiotemporal Clustering of Drop-Off Points

“…Because most cars are installed with satellite-positioning devices, the spatiotemporal information of trajectory data can be uploaded to computer servers via mobile communication technology at regular time intervals. In public transportation, taxis are the closest to destinations compared to subways and buses [8][9][10][11]. Furthermore, we can suppose that the location There may be several solutions; for example, monitoring sensors, such as camera surveillance systems, can be installed to capture real-time videos or images for each entrance [3].…”

“…Human mobility and travel behaviors have a strong regularity characteristic [12][13][14], and previous studies have verified the differences between macro and micro travels through various kinds of trajectory data [15], which form the basis of research about predictions and spatiotemporal distribution of travel behavior [16]. Floating car data (FCD) is widely used in traffic flow forecasting [11,17], traffic congestion analysis [9], time and space distribution of traffic conditions [18], traffic accessibility [19], and traffic hotspot discovery [10]. Drop-off points are a particular type of signal point in trajectory data, which are extracted by the vacancy status changes of taxicabs, and are now widely used for finding hot spots of urban human flow [20], revealing urban structures [21] and unveiling the relationship between land use and human mobility [22].…”

Weak Nodes Detection in Urban Transport Systems: Planning for Resilience in Singapore

“…Gianni Barlacchi has been partially funded by the EIT project Cedus. ing human movements allows planners and policy-makers to face relevant urban challenges through computational methods [1], [4]- [6], [12], [15], [32], [33], [37]. While the observation of mobility flows offer for instance the possibility to investigate the inner workings of urban transport systems, this is not enough for efficient transport planning.…”
