Determinants of Tunisian multimodal travel choice: a hybrid model based on multinomial logit and wavelet transform

This paper aims to analysing the Tunisian multimodal travel choice in the Sahel region using a hybrid model based on multinomial logit and wavelet thresholding. Data are collected through a questionnaire. Thereby, it is found that travellers who choose 'taxi-metro' give a great importance to the trip comfort and the value of time but they do not give any to the travel cost. However, the passengers choosing 'taxi-bus' and 'taxi-hire' are less interested in the travel comfort than the trip cost. The results also underline the positive impact of transfer facilities including 'restroom', 'seat', 'information', 'security agent' and 'security tools' on passengers' comfort perception. For bus and hire transit, it is found that an adequate level of cleanliness, an easy access to hire station, the presence of restaurants and shelters and a minimum degree of crowdedness reduces significantly the burden of traveling and increases the using of 'taxi-bus' and 'taxi-hire' rather than 'taxi-metro'.
