Using GPS Data to Understand the Day-to-Day Dynamics of the Morning Commute Behavior

چکیده
This paper examined the day-to-day variability of the journey-to-work trips, including the departure time, route choice, and trip chaining behavior, using GPS-based disaggregate morning commute data of 56 drivers during a one-week period. Data were collected from the ongoing instrumented vehicle projects in Atlanta sponsored by NHTSA and FHWA. The paper examines alternate measurements of the day-to-day variability of the commute pattern. While commuting trips are often thought to be highly repetitious and therefore highly predictable trips, research results of this paper show that commuters change departure times more frequently than routes, and trip chaining significantly impact commuters’ departure time and route choice behavior. This paper begins to explore definitions and relationships that will be necessary to the better understanding of the day-to-day commute dynamics.

An Analysis of Morning Commute Route Choice Patterns Using GPS Based Vehicle Activity Data
This paper examines the morning commute route choice behavior of 182 drivers, using disaggregated GPS-based activity data collected during a ten-day period. This paper attempts to describe how these commuters tend to behave in the real world. A binary logit model of morning commuters’ choice between using a single commute route and multiple routes was established, based upon the evidence of dri...

Combining Neural Network with Genetic Algorithm for prediction of S4 Parameter using GPS measurement
The ionospheric plasma bubbles cause unpredictable changes in the ionospheric electron density. These variations in the ionospheric layer can cause a phenomenon known as the ionospheric scintillation. Ionospheric scintillation could affect the phase and amplitude of the radio signals traveling through this medium. This phenomenon occurs frequently around the magnetic equator and in low latitu...

Global positioning system (GPS) measurements provide accurate and continuous 3-dimensional position, velocity and time data anywhere on or above the surface of the earth, anytime, and in all weather conditions. However, the predominant ranging error source for GPS signals is an ionospheric error. The ionosphere is the region of the atmosphere from about 60 km to more than 1500 km above the eart...

Background: Our body is under the influence of a 24-hour period which regulates body temperature, blood pressure, metabolism, hormone secretion and their functions. Thus, it is probable that while doing exercise or following that the function of the body varies in different parts of the day. The goal of the present study was to assess the effect of the time of exercise (morning or evening) on t...
