Freeway Travel Speed Calculation Model Based on ETC Transaction Data
Real-time traffic flow operation condition of freeway gradually becomes the critical information for the freeway users and managers. In fact, electronic toll collection (ETC) transaction data effectively records operational information of vehicles on freeway, which provides a new method to estimate the travel speed of freeway. First, the paper analyzed the structure of ETC transaction data and ...
متن کاملA Freeway Travel Time Reliability Study
The objective of this study was to identify measures appropriate to estimate travel time reliability and apply them to study the reliability of travel time under varying freeway operating conditions. More specifically, a case study was undertaken to study travel time reliability along the I-65 corridor in the State of Alabama. The objectives of this study were to: a) Calculate reliability metri...
متن کاملOn Cybersecurity of Freeway Control
1 This article focuses on cybersecurity of transportation systems and investigates their vulnerability 2 to attacks on the sensing and control infrastructure. An array of different attack points, classi3 fied into physical, close-proximity, and virtual layers, are reviewed and investigated. We construct 4 two benchmark scenarios which exploit these vulnerabilities to identify the potential harm...
متن کاملQuantifying effects of ramp metering on freeway safety.
This study presents a real-time crash prediction model and uses this model to investigate the effect of the local traffic-responsive ramp metering strategy on freeway safety. Safety benefits of ramp metering are quantified in terms of the reduced crash potential estimated by the real-time crash prediction model. Driver responses to ramp metering and the consequent traffic flow changes were obse...
