Empirical validation of network learning with taxi GPS data from Wuhan, China
Susan Jia Xu, Qian Xie, Joseph Y. J. Chow +1
In prior research, a statistically cheap method was developed to monitor transportation network performance by using only a few groups of agents without having to forecast the popu…
Online monitoring of local taxi travel momentum and congestion effects using projections of taxi GPS-based vector fields
Xintao Liu, Joseph Y. J. Chow, Songnian Li
Ubiquitous taxi trajectory data has made it possible to apply it to different types of travel analysis. Of interest is the need to allow someone to monitor travel momentum and asso…
Scaling of Geographic Space as a Universal Rule for Map Generalization
Bin Jiang, Xintao Liu, Tao Jia
Map generalization is a process of producing maps at different levels of detail by retaining essential properties of the underlying geographic space. In this paper, we explore how…
Defining and Generating Axial Lines from Street Center Lines for better Understanding of Urban Morphologies
Xintao Liu, Bin Jiang
Axial lines are defined as the longest visibility lines for representing individual linear spaces in urban environments. The least number of axial lines that cover the free space o…
Scaling of Geographic Space from the Perspective of City and Field Blocks and Using Volunteered Geographic Information
Bin Jiang, Xintao Liu
Scaling of geographic space refers to the fact that for a large geographic area its small constituents or units are much more common than the large ones. This paper develops a nove…
Computing the Fewest-turn Map Directions based on the Connectivity of Natural Roads
Bin Jiang, Xintao Liu
In this paper, we introduced a novel approach to computing the fewest-turn map directions or routes based on the concept of natural roads. Natural roads are joined road segments th…
AxialGen: A Research Prototype for Automatically Generating the Axial Map
Bin Jiang, Xintao Liu
AxialGen is a research prototype for automatically generating the axial map, which consists of the least number of the longest visibility lines (or axial lines) for representing in…
