GENERATING PROBABILISTIC PATH OBSERVATION FROM GPS DATA FOR ROUTE CHOICE MODELING

Michel Bierlaire, Jingmin Chen, Jeffrey Newman

Abstract: Map matching algorithms are the conventional way to generate path observations from GPS data for route choice models. The deterministic matching may introduce extra biases to parameters of route choice models if the matching is wrong. In this pap ...

Generating probabilistic path observation from GPS data for route choice modeling

Michel Bierlaire, Jingmin Chen, Jeffrey Newman

Map matching algorithms are the conventional way to generate path observations from GPS data for route choice models. The deterministic matching may introduce extra biases to parameters of route choice models if the matching is wrong. In this paper, a new ...

Map Matching using a multi-hypothesis approach

Modern navigation systems use multi-sensor-systems for location determination in combination with GPS or DGPS. Limitations in the availability of satellites due to shadowing and multi path effects in urban areas, magnetic disturbances, wheel slips and erro ...

Improving matrix estimation pertaining to detailed traffic information and sophisticated traffic state

Technical innovation and extensive application of adaptive signal control at intersections have made turning flow information that provide more precise constraints for Origin-Destination matrix (O-D matrix) estimation easily available in great quantity and ...

Route choice analysis

Emma Frejinger

This thesis focuses on the route choice behavior of car drivers (uni-modal networks). More precisely, we are interested in identifying which route a given traveler would take to go from one location to another. For the analysis of this problem we use discr ...

Route choice modeling with network-free data

Michel Bierlaire, Emma Frejinger

Route choice models are difficult to design and to estimate for various reasons. In this paper we focus on issues related to data. Indeed, real data in its original format are not related to the network used by the modeler and do therefore not correspond t ...

Improving pedestrian dynamics modelling using fuzzy logic

Kamiar Aminian, Bertrand Merminod, Phillip Tomé, François Bonzon

The complementary nature of MEMS based pedestrian dead-reckoning (PDR) navigation and GNSS (Global Navigation Satellite System) has long been recognised. The advantages are quite clear for those applications requiring indoor positioning and that, for one r ...

Map-matching for pedestrians via Bayesian inference

Michel Bierlaire, Bertrand Merminod

A navigation process is to start from a known (initial) position and to ensure a continued localisation of the user during the movement. Consider a pedestrian navigation system which contains a GPS receiver and a set of inertial sensors connected with the ...

Bayesian Approach for Indoor Pedestrian Localisation

Michel Bierlaire, Bertrand Merminod

The principal concept of navigation is to start from a known (initial) position and to ensure a continued and reliable localisation of the user during his/her movement. The initial position of the trajectory is usually obtained via GPS or defined by the us ...
