A 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 کاملA Multi - State Travel Time Reliability Model
Travel time unreliability is an important characterization of transportation systems. The appropriate modeling and reporting of travel time reliability is crucial for individual travelers as well as management agencies. In this paper, a novel multi-state model is proposed for travel time modeling and reporting. The model advances travel time modeling in two aspects. First, the multi-state model...
متن کاملMonitoring Travel Time Reliability from the Cloud: Cloud Computing Based Architecture for Advanced Traffic Information Dissemination
Under the existing loosely-distributed sensoring environment with heterogeneous data sources, transportation planning and management agencies have found a critical need for efficiently storing, processing and extracting desirable corridor-level and network-level information through a systematic and seamless integration of data sources. Extracting travel time variability and trip reliability inf...
متن کاملContinuous Monitoring of Crosswell Seismic Travel Time
In two separate shallow field experiments, at two distance scales, we have used continuous monitoring to estimate the effect of barometric pressure on crosswell travel time and thereby calibrated the stress sensitivity of the rock volume between the wells. In a 3 m experiment we found a stress sensitivity of 10/Pa while in a 30 m experiment the sensitivity was 5 x 10 /Pa. Results from a deeper ...
متن کاملAssessment and Monitoring for Railway Tracks Reliability and Safety using Nondestructive Testing Measurement Systems
The deterioration of railway tracks raises great concerns about the integrity of assessments and evaluations of railway tracks currently in service. Integrated inspection strategies coupled with innovations in inspection technology can lead to significant improvements in operational cost efficiency and reliability without the requirement of a fundamental shift in the existing understanding o...
