Abstract

This research argues the effect of road tolls on the travel demand; it also discusses and identifies the factors that influence the willingness to pay road tolls while taking into consideration the changes that the number of users may make within the road condition. The aim of this research is to estimate the function of the travel demand of road users number, with each price, that satisfy their expectation of the speed of travel.

Within this research, a stated preference survey (SP) has been prepared. The survey describes two travel situations:

1: traveling in a free of charge road while the duration of travel is close to the original travel time of the interviewee.

2: traveling in a toll road while the price of the toll, the duration of the travel and the variant in travel time that define the new travel conditions.

The research includes two main steps:

1.                  Executing the experiment.

The experiment was carried out according to the principles of SP. Within the experiment, hypothetical travel conditions were described by different travel conditions. Each observation that was taken in the experiment depends on the interviewee decision on whether to choose one of the following situations:

a.       To keep traveling in the same road and the same travel conditions.

b.      To travel in an alternative road in a better condition and to pay road toll.

2.                  Results analysis:

The number of the interviewees who answer the questions in consequential way was 153 interviewees. Analysis of the interviewees reactions in light of the hypothetical conditions described to them were based on the utility approach for the demand theory.

Within this research, five significant results were found:

1.                  The toll may result in decrease the travel in a private car.

2.                  Travel conditions significantly affect the travel demand.

3.                  The demand for traveling in alternative toll road is elastic (-2.7) compared to the acceptable elasticity values (-1).

4.                  There are number of factors related to the characteristic of the drivers and their driving habits that affect their willingness to pay road tolls.

5.                  The value of saved time is not fixed.

The research findings may help decision makers in the policy of the demand management, On the one hand, by examining the advisability of establishing different transportation projects. On the other hand, minimizing the dimensions of the congestion problem throughout minimizing the use of a private car.
