Modeling multi-modal traffic in cities
(2018)We propose a new functional form for the 3D-MFD. The 3D-MFD links the number of cars and buses in an urban network to the total travel production. The parameters of the functional form are derived from the structure and topology of the road and bus network. The physical interactions of vehicles are described by a single parameter. We apply the methodology to two empirical data sets from London and Zurich, and discuss policy relevant ...Conference Paper -
Route and mode choice models using GPS data
(2017)TRB 96th Annual Meeting Compendium of PapersGPS data has become almost ubiquitous and data collection and processing technologies have advanced considerably. In transportation research, GPS traces are used, along with other data sources, to construct travel diaries, as they promise higher accuracy of collected data, combined with fewer fatigue effects. In this research, we present such a study, where a sample from Zurich, Switzerland, used GPS devices to monitor their daily trips ...Conference Paper -
Approximative network partitioning for MFDs from stationary sensor data
(2018)Macroscopic fundamental diagrams (MFD) are typically estimated for sub-regions in cities, where the zoning conventionally follows the directive of homogeneity in the road network and traffic. Existing network partitioning algorithms fail to work for MFD estimation with stationary sensor data as their link speed and link density measurement are biased by the location of the sensor. However, in this paper, we present an approach for ...Conference Paper -
