Estimation of Travel Times on Signalized Arterials

Paper describes procedure for estimation of travel times on signalized arterial roads based on multiple data sources with application of dimensionality reduction. Travel time estimation approach incorporates forecast of transortation nodes impedance and travel time on network links. Forecasting period is two hours and estimation is based on historical data and real time data on traffic conditions. Travel time estimation combines multivariate regressiona, principal component analysis, k-nearest neighbours, cross validation and exponentially weighted moving average method.
