Abstract

The quality in public transport is a relevant factor affecting travellers’ behaviour. Recently, research has improved methods and models to evaluate the attributes that mostly influence users’ satisfaction about the trip. The role of quality in the field of travel choices is an under-researched topic. Existing contributions mainly focus the attention on service reliability and travel time, travel information, ticket, access to the terminals, while little attention was dedicated on the influence of the comfort and safety perception produced by the architectural design and the public spaces of the transport terminals. Starting from this gap in the literature, the objective of this research was to evaluate the effects of quality in public transport (aesthetics, comfort, perception of security and travel experiences) in users’ choices. Specifically, original element of this research has been to propose methods and models (functional forms and/or specific attributes) unconventional, aimed at better reproduce the decision-making process, including the specification of measures able to quatify users’ attitude and perception not directly measurable (e.g. latent variables) and function of the traveler . Innovative element of the estimated models is also related to their application fields, that are, a greater ability to quantify (evaluate) the impacts arising from high quality public transport infrastructures and services (e.g. transport terminals of high aesthetic and architectural standard, more services to travelers, on-board comfort, infomobility). Among the estimations proposed in this thesis there were: (A.). Non-conventional attributes able to quantify the quality attributes and applied to a bus transport extra urban case study (B).non-conventional model specifications using latent variables applied to a rail transport urban case study In the first part of research for the case study of bus public transport, a mobility survey was carried at national scale, considering the bus terminals in Milan, Rome, Naples, Avellino end Crotone. SP scenario were proposed to 1,100 respondents allowing to estimate a switching (change vs. not changes) model (with serial correlation in residuals) toward an high-quality terminal increasing the ticket price or reducing the bus frequency but could use of the high quality of the terminal. Estimation results show that the hedonic value (at national scale) related to a high quality bus terminal is 2.5 €/trip (the 19% of the ticket price). This value increases for the cities in the Centre and North Italy, and decreases for the South ones (5.9 €/trip (31% of the ticket price and 136% greater than the average value of the panel) for Milan-Nord and 0.6 €/trip (16% of the ticket price and 76% less than the average value of the panel) for Avellino-South). A “travel experience effect” was also observed; the average hedonic value (of an high quality bus terminal) decrease to 2,1€/trip (-16%) if the user carry out a “long trip” (travel time greater than 2 hours and/or more than one transport mode used) under a medium-low quality. The opposite occurs for the “short trips” (hedonic value equal to 3.0 €/trip -+20%). This means that if a passenger has to face a long journey under medium-low quality, he will assign a lower value to the high quality terminal, since he will benefit them for shorter time (lower willingness to pay in a travel experience context). For the second model estimation (No-conventional modeling specifications using latent variables applied to urban rail quality), the case study was the metro system of Naples where there are several origin-destination pairs (e.g. historical center of Naples towards central station) that are served by two different lines competing each other in terms level of service attributes (e.g. travel time, waiting time, fare), but completely different in terms of aesthetic and quality of the stations. A mobility survey was carried in 2016, interviewing about 550 users in three different stations belonging to the investigated lines, asking to describe their travel details, socioeconomic characteristics and to respond to specific psychological tests (e.g. cognitive behavioural assessment) aimed to capture users’ attitudes and perceptions. A Hybrid Choice Model was calibrated considering different latent variables in order to grasp aesthetic, comfort and safety attitudes. Estimation results showed that users who have a greater perception of art and comfort and safety attitude, were more likely to choose the metro-line with high architectural and aesthetic standards (with no differences for other attributes).
