Abstract
The objective of this paper was the modelling of commuters' reactions to both en-route and pretrip information advising route diversions due to construction of the West LRT (Light Rail Transit) in the City of Calgary, Canada. The West LRT line construction primarily affected the daily commute through the Bow Trail and 1 ih Avenue SW corridors between downtown and 69th Street SW. Many road closures occurred in the vicinity of the LRT construction zones. Data on commuters' route-making decisions were obtained by conducting a revealed preference and stated preference survey on a sample of users of the main affected roads. A discrete choice model was calibrated to model the changes in travel behaviour under the influence of an advance traveller information system. In this model, the effects of various factors, such as sources of congestion information (radio, television, West LRT website, newsletters and variable message signs (VMS)), various demographic characteristics, congestion level, trip characteristics, weather conditions, frequency of driving in the vicinity of the LRT construction zone, familiarity with alternative routes and route characteristics, on the decision to divert or not to divert were considered. Statistical tests showed that drivers switched their mode during the West LRT construction. Multinomial logistic regression models were estimated to examine the drivers' reactions to both pre-trip information (newsletters) and en-route information (VMS). The model results indicated that drivers' preferred the use of variable message signs to that of newsletters.
