Public Preferences

Shared autonomous vehicles (SAVs) are rapidly emerging as a viable alternative form of public transportation with the potential to provide adequate and user-friendly, on-demand services without having vehicle ownership. It has been argued that SAVs could revolutionize transportation systems and our current way of life. Although SAVs are likely to be introduced in developed countries first, there is little doubt that they would also have a significant effect and enormous market in developing nations. This study aimed to investigate the factors that influence public acceptance of SAVs, as well as the current public attitude toward SAVs, in two developing countries, namely, Pakistan and China. A stated preference survey was conducted to understand respondents’ travel patterns, preferences, and sociodemographic data. A total of 910 valid responses were gathered: 551 from Lahore, Pakistan, and 359 from Dalian, China. A multinomial logit model and a mixed multinomial logit model with panel effect were used for data analysis. The results suggested that generic attributes, such as respondents’ waiting time, travel time, and travel cost were found to be significant in both cities. The results indicate that sociodemographic characteristics, such as education, income, travel frequency in a week, and people who had driver’s licenses, are significantly correlated with respondents’ interest in using SAV in Lahore. The results also showed that people who had a private car indicated a greater interest in SAVs in Dalian. The study provides a new perspective to understand the public preferences toward SAVs in developing countries with different economies and cultures, as well as a benchmark for policymakers to make effective policies for the future implementation of SAVs.

With the rapid rise in problems associated with use of motorcycles as alternative means to inadequate public transportation, this study seeks to identify household factors influencing motorcycle ownership in Makurdi. The study estimates the influence of the various household factors identified and a model for predicting motorcycle ownership is developed for the study area. Data were collected via a questionnaire survey of 1412 households in the study area. The survey revealed that the number of motorcycles owned per household in the low density zone was 0.67 while that for the medium and high density zones was 0.62 and 0.79 respectively. The multinomial logit model developed predicted that 67% of households owned motorcycles as compared to 71% observed from survey data.  Severity applications of the model to test the effects of changing economic situations on motorcycle ownership showed that residents of the study area are more disposed to owning motorcycles in periods of recession than periods of economic boom. The study gives an understanding of motorcycle growth pattern and ownership characteristics in the study area and will therefore serve as a relevant input for planning, regulation and control of motorcycle activities in the study area.

Most of motorized trips in cities of middle and small size are made in public transport and mainly in private vehicle, this has caused a saturation in parking systems of the cities, causing important problems to society, one of the most important problems is high occupancy of public space by parking systems. Thus, is required the estimation of models that reproduce users’ behaviour when they are choosing for parking in cities, to carry out transport policies to improve transport efficiency and parking systems in the cities. The aim of this paper is the specification and estimation of models that simulate users’ behaviour when they are choosing among alternatives of parking that there are in the city: free on street parking, paid on street parking, paid on underground parking and Park and Ride (now there isn´t). For this purpose, is proposed a multinomial logit model that consider systematic and random variations in tastes. Data of users’ behaviour from the different alternatives of parking have been obtained with a stated preference surveys campaign which have been done in May 2015 in the principal parking zones of the city of Santander. In this paper, we provide a number of improvements to previously developed methodologies because of we consider much more realism to create the scenarios stated preference survey, obtaining better adjustments.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4071

The paper investigates the influence of different model specifications for interpreting the results of discrete choice experiments when investigating heterogeneous public landscape preferences. Comparing model specifications based on the Mixed Multinomial Logit and the Generalized Multinomial Logit Model reveals that the parameter estimates appear qualitatively comparable. Still, a more in-depth investigation of the conditional estimate distributions of the sample show that parameter interactions in the Generalized Multinomial Logit Model lead to different interpretations compared to the Mixed Multinomial Logit Model. This highlights the potential impact of common model specifications in the results in landscape preference studies.

Kota Bekasi adalah kota urban yang dekat dengan Jakarta, ibukota Indonesia. Lebih dari setengah orang Bekasi melakukan kegiatan di Jakarta. Penelitian ini dilakukan untuk mendeskripsikan preferensi pilihan moda penduduk Bekasi yang pergi berkomuter ke Jakarta. Pilihan modanya adalah antara mobil pribadi, Transjakarta (BRT) dan KCL (Kereta Api). Empat atribut diidentifikasi sebagai pertimbangan pilihan moda  yaitu biaya perjalanan, waktu perjalanan, frekuensi dan keterlambatan perjalanan. Metode yang digunakan untuk mengumpulkan data adalah dengan Stated Preference survei. Selanjutnya, data dianalisis dan dimodelkan dengan multinomial logit model menggunakan software R untuk menghasilkan model terbaik dalam menggambarkan pilihan moda. Meskipun sebagian pengguna mobil pribadi ingin mengubah moda transportasinya ke Transjakarta dan KCL tetapi waktu perjalanan, biaya perjalanan, frekuensi dan penundaan perjalanan bukanlah atribut penting yang dapat mengubah preferensi mereka. Pengguna KCL adalah kelompok yang paling mungkin yang akan mengubah modenya menjadi Transjakarta dengan pertimbangan waktu perjalanan dan frekuensi perjalanan. Probabilitas kemungkinan akan terjadi pada pengguna dengan usia di atas 50 dengan 0,29 dan pengguna di bawah 50 tahun dengan 0,099.

Using the Nepal Living Standard Survey (NLSS) data, this article identifies the determinants of household’s choice of energy for the purpose of cooking and verifies the energy ladder hypothesis (ELH). A multinomial logit model (MNL) is applied to fulfil this objective. It has been found that cleaner energy is more likely to be used in households where the head of the family has a higher level of education and a higher level of income, whereas larger households and households with higher proportion of dependent members, older person or female as head of the family and rural households are less likely to use cleaner energy. Households located in a place far from markets also do not choose cleaner energy. Further, the likelihood of using cleaner energy in the mountain and Terai regions is less than that in the hilly region. This article applies an ordered logit to the same set of data and confirms the robustness of the results. Suitable policy measures have been suggested to enable a transition towards cleaner sources of energy instead of inferior sources in Nepal.
