Automating mode detection for travel behaviour analysis by using global positioning systemsenabled mobile phones and neural networks
TLDR
The mode detection technique presented in this article can be optimised using a critical point, pre-processing algorithm to reduce the size of required GPS datasets obtained from GPS-enabled mobile phones, thus reducing data collection costs while conserving precious mobile phone resources such as battery life.
Automating Mode Detection Using Neural Networks and Assisted GPS Data Collected Using GPS-Enabled Mobile Phones
TLDR
The authors demonstrate how this technique can be optimized using a critical point algorithm to reduce the size of required GPS datasets obtained from GPS-enabled mobile phones, thus reducing data collection costs while saving mobile phone resources such as battery life and storage space.
Creative Solutions for Assessing Level of Service Equally Across Modes
Transportation professionals base the level of service (LOS) for automobile, bicycle, pedestrian, and transit modes on various criteria, and therefore the LOS is calculated differently for each mode.…
Dynamic Management of Real-Time Location Data on GPS-Enabled Mobile Phones
TLDR
Two complementary algorithms are presented: the critical point (CP) algorithm, which filters data points to be transmitted to the server, and the location-aware state machine, which dynamically manages the frequency of the location re-calculation update rate.
