Travel Time Forecasting and Dynamic Od Estimation in Freeways Based on Bluetooth Traffic Monitoring
From the point of view of the information supplied by an ATIS to the motorists entering a freeway of one of the most relevant is the Forecasted Travel Time, that is the expected travel time that they will experience when traverse a freeway segment. From the point of view of ATMS the dynamic estimates of time dependencies in OD matrices is a major input to dynamic traffic models used for estimat...
متن کاملArterial Travel Time Estimation for Advanced Traveler Information Systems
While vehicular flows on freeways are often treated as uninterrupted flows, flows on arterials are conceivably much more complicated since vehicles traveling on arterials are not only subject to queuing delay but also to signal delay. Prediction of travel time is potentially more challenging for arterials than for freeways. This paper proposes a simple approach for arterial travel time predicti...
متن کاملImproving the Estimation of Travel Demand for Traffic Simulation: Part II
This report examined several methods for estimating Origin-Destination (OD) matrices for freeways, using loop detector data. Least squares based methods were compared in terms of both off-line and on-line estimation. Simulated data and observed data were used for evaluating the static and recursive estimators. For off-line estimation, four fully constrained least squares methods were compared. ...
متن کاملIncorporating Within-Day Transitions in the Simultaneous Off-line Estimation of Dynamic Origin-Destination Flows without Assignment Matrices
An off-line methodology for simultaneously estimating dynamic origin-destination matrices without using assignment matrices that incorporates within day transition equations is presented. The proposed formulation and solution approach extend a calibration method recently developed that directly uses the output of any network loading model (such as a dynamic traffic assignment or simulation mode...
متن کاملA robust framework for the estimation of dynamic OD trip matrices for reliable traffic management
Origin-Destination (OD) trip matrices describe the patterns of traffic behavior across the network and play a key role as primary data input to many traffic models. OD matrices are a critical requirement, either in static or dynamic models for traffic assignment. However, OD matrices are not yet directly observable; thus, the current practice consists of adjusting an initial or a priori matrix ...
