Value of Time Evaluation of High-Speed Railway Users in Turkey
High-Speed Rail (HSR) has a high travel time reduction potential and competes against both road and air travel modes. Turkey started the HSR services in 2009 and has four operating lines with three more lines expected to serve in the near future. As it is a newly introduced transportation mode in Turkey, the scientific research about HSR is very limited. Thus, this study mainly aims to shed light on the competitiveness of HSR in Turkey and the Value of Time (VoT) of HSR users. Thus, a face-to-face survey was conducted with 421 HSR passengers at four HSR stations (Ankara, Eskişehir, İstanbul and Konya). Based on survey data, first, binary logit models were developed as HSR versus “next best alternative” mode choice in “no-HSR situation” which was the information collected via surveys. Most commonly referred parameters (such as travel time, cost, travel time reduction, income, etc.) and their variations were used in the binary logit models and a series of binary logit models were developed. The major parameter affecting HSR choice was detected as travel time reduction of HSR. Then, selected binary logit models having statistically significant results were used to estimate VoT of HSR users. As there are many different parameters in determining airway ticket prices (ticketing time, air service types, etc.), two different air cost levels were determined as average of: i) low cost airline ticket price (Alternative A), ii) economy class ticket price (Alternative B). Variation in the airway ticket price has a considerable impact in general and line based VoT calculations. VoT which was calculated with Alternative B presented lower values compared to the values calculated by Alternative A. Besides the sensitivity analyses based on airline ticket prices, cost damping analyses were also conducted using box-cox transformation and logarithmic transformation for cost. As a result, VoT estimations varied among both HSR lines and different traveler groups. When compared to hourly cost of transportation modes serving in each HSR corridor, VoT values were much higher for some corridors, but for the HSR corridors having a strong airway alternative, VoT values were found as acceptable as it is not a paid value in reality but only a perceived one.
