Spatiotemporal Patterns of Urban Human Mobility
TL;DR: This study considers the data obtained from smart subway fare card transactions to characterize and model urban mobility patterns and presents a simple mobility model for predicting peoples’ visited locations using the popularity of places in the city as an interaction parameter between different individuals.
Understanding Urban Human Activity and Mobility Patterns Using Large-Scale Location-Based Data from Online Social Media
TL;DR: Urban human mobility and activity patterns are analyzed using location-based data collected from social media applications (e.g. Foursquare and Twitter) to characterize aggregate activity patterns and characterize individual activity patterns.
Journal ArticleDOI
Urban activity pattern classification using topic models from online geo-location data
Samiul Hasan,Satish V. Ukkusuri +1 more
TL;DR: A data-driven modeling approach, based on topic modeling, is proposed to classify patterns in individual activity choices and provides an activity generation mechanism which when combined with the data from traditional surveys is potentially a useful component of an activity-travel simulator.
Journal ArticleDOI
The role of built environment on pedestrian crash frequency
TL;DR: In this article, the link of land use and road design on pedestrian safety and the effect of the level of spatial aggregation on the frequency of pedestrian accidents was investigated for New York City based on an extensive dataset collected from different sources over a period of 5 years.

A linear programming formulation for autonomous intersection control within a dynamic traffic assignment and connected vehicle environment
Feng Zhu,Satish V. Ukkusuri +1 more
TL;DR: In this paper, a linear programming formulation for autonomous intersection control (LPAIC) is proposed to account for traffic dynamics within a connected vehicle environment, where a lane based bi-level optimization model is introduced to propagate traffic flows in the network, accounting for dynamic departure time, dynamic route choice, and autonomous intersections control in the context of system optimum network model.
