The introduction of innovative transportation policies in general, and road pricing in particular, has become a main concern in both developed and developing countries due to increasing mobility. The success of a new pricing policy, however, largely depends on public acceptance, therefore investigating driver responses to pricing must be treated with utmost priority. This study investigates driver response to a proposed toll motorway project connecting the cities of Corinth and Patras in Greece. The Greek Government realizes that road pricing is a useful policy for advancing private-public partnerships, market liberalization, financing road infrastructure and enhancing mobility. The proposed toll motorway is a section of 774 km long motorway spine in Greece and therefore it will be a key undertaking in terms of the country’s economy. Analysis of intercity route choice behavior of road users and driver sensitivity to road pricing are the main objectives in this study. The toll motorway project has yet to be implemented and therefore actual travel data or revealed preference (RP) data do not exist at this stage. Hence, this study uses stated preference (SP) data in the analysis. A binary choice model is developed with the choice options: a dual carriageway with full grade separation (proposed toll motorway) and existing alternative routes (single carriageway toll motorway and scenic coastal road). Socio-economic and journey related characteristics of current road users along with their stated preferences for the proposed toll motorway are explicitly incorporated in the model estimations. Attributes of travel time, travel cost, road type, toll charge, travel distance, frequency, purpose and income are included in the model to elicit route choice behaviors of intercity travelers.
