A PROBABILITY MODEL OF THE USE OF TOLL ROUTES WHEN NON-TOLL ALTERNATIVES EXIST

The subject of this study is to analyze the profile of and the probability that motorists will use the toll routes when alternative non-toll routes exist. The authors assume that this probability depends on the demographic and economic characteristics of the motorists, the purpose of the trips, the distance to be covered, and the amount of time they expect to save by using the toll route. Some of the issues in the literature, ranging from the methods of calculating highway tolls, to the political aspects of highway tolls, fuel cost and travel behavior have been discussed in previous studies. The main emphasis of this study is the time saving and the indirect cost and purpose of the travel.
