Glerum A., Atasoy B., Bierlaire M. (2014). Using semi-open questions to integrate perceptions in choice models. Journal of Choice Modelling 10 :11-33

This research investigates the measurement of perceptions by means of adjectives freely reported by respondents in semi-open questions. It involved the use of semi-open responses of 1'763 Swiss individuals to develop indicators for a latent variable representing the perception of comfort of public transportation. The indicators are then incorporated into a discrete choice model of revealed mode choices. Perceptions are assumed to impact choice significantly and this research aims at capturing their complexity using adjectives and integrating them into the hybrid choice modeling framework. We exploit a quantification of the adjectives performed by external evaluators. Given the subjectivity that is involved, we analyze the sensitivity of the results across evaluators who rated the adjectives. We observe that the aggregate indicators of demand, such as market shares, elasticities and values of time, are rather robust across evaluators. This is not the case for the disaggregate indicators that may vary substantially across evaluators.

In the context of the arrival of electric vehicles on the car market, new mathematical models are needed to understand and predict the impact on the market shares. This research provides a comprehensive methodology to forecast the demand of a technology which is not widespread yet, such as electric cars. It aims at providing contributions regarding three issues related to the prediction of the demand for electric vehicles: survey design, model estimation and forecasting. We develop a stated preferences (SP) survey with personalized choice situations involving standard gasoline/diesel cars and electric cars. We specify a hybrid choice model accounting for attitudes towards leasing contracts or practical aspects of a car in the decision-making process. A forecasting analysis based on the collected SP data and market data is performed to evaluate the future demand for electric cars.

Atasoy B., Glerum A., Bierlaire M. (2013). Attitudes towards mode choice in Switzerland. disP - The Planning Review 49 (2):101-117

We integrate latent attitudes of individuals into a mode choice model through latent variable and latent class models with the help of psychometric indicators that enable us to measure these attitudes. The aim of the inclusion of attitudes is to better understand the underlying choice preferences of travelers and therefore increase the forecasting power of the choice model. We first present an integrated choice and latent variable model where we include attitudes towards public transportation and environmental issues explaining the utility of public transport. Secondly we present an integrated choice and latent class model where we identify two segments of individuals having different sensitivities to the attributes of the alternatives resulting from their individual characteristics. Calibration of these types of advanced models on our sample has demonstrated the importance of attitudinal variables in the characterization of the population heterogeneity.

A DYNAMIC VEHICLE CHOICE FORECASTING FRAMEWORK

The aim of this research project is to develop a dynamic model framework to forecast car demand. The model-system jointly accounts for behavioural variables (e.g. household evolution, individual motivations), institutional factors (e.g. incentives and taxation) and market features (e.g. new fuel or vehicle technology launches) to forecast vehicle acquisition. The project benefits from a large-scale, longitudinal dataset on vehicle transactions from major European markets. Methodologically the framework consists of a system of aggregate, disaggregate and duration-based choice models, accounting for dynamic features of the decision at each stage. Importantly, the proposed dynamic framework enhances realism by representing the durability of possession, rapid changes in value across product and ownership cycles and uncertainty about future market developments and institutional factors. The proposed framework sheds light on the timing and type of vehicle ownership, illustrating the benefits of taking the first steps away from a static approach. The findings will aid the prediction of consumer behaviour in response to critical policy variables, such as incentives, alongside market dynamics, such as the appearance and diffusion of novel technologies. A deeper understanding of future vehicle choice behaviour is critical given sizable institutional and industrial investments to promote alternative vehicle technologies with a final aim to improve energy efficiency in the transportation sector.

OPTIMA: Inferring transport mode preferences from attitudes

Swiss Post and PostBus have launched a research project to optimize mobility in cooperation with the Federal Institute of Technology in Lausanne (EPFL), represented by EPFL Transportation Center, under Professor Michel Bierlaire. This will show the market potential for combined mobility. Among other things it will look at the factors that influence travellers in their choice of transport. At a later stage, target group-specific new transport offerings and services will be developed and tested, which will have a lasting influence on this choice. The three years research project is conducted by Professors Vincent Kaufmann (LASUR) and Michel Bierlaire (TRANSP-OR).

Modelling car ownership duration, Natalie Sauerwald (Mathematics)

Supervision: Amanda Stathopoulos, Aurélie Glerum
Household vehicle ownership influences many aspects of travel demand, with pronounced impact for energy consumption, travel mode distribution, residential location patterns and city attractiveness. Despite a large number of vehicle choice models focusing on the type of car chosen, formal modelling of the timing and duration of ownership has received relatively little attention. Statistical models known as duration (hazard) models can be used to estimate the distribution of vehicle ownership lengths in a population. A central interest is to identify the determinants of the time that elapses between two automobile transactions, including characteristics of the car and household and macroeconomic/policy variables. In addition, the influence of less tangible factors such as expectations regarding the market, future vehicle launches, propensity for planning and personal aspirations may have a large impact on the timing of renewal and vehicle ownership duration. We have a large dataset available containing rich information on vehicle acquisitions and are looking for a student to collaborate on data elaboration, exploration and development of a duration model for vehicle ownership. Several assumptions for the hazard function and innovative determinants of ownership spells will be considered. The student should be familiar with management of large data, statistics/econometrics and have some notion of behavioral theories of decision-making.

Transportation mode choice models including word data, Peng Cui (Mathematics)

Supervision: Aurélie Glerum
Recently, there has been an emphasis in the discrete choice literature on the introduction of attitudes and perceptions into discrete choice models. We are interested to see how these factors impact on choice. A joint work with social scientists has led to the development of new surveys which include questions on the perception of transportation modes. In the framework of a survey conducted with CarPostal, the following question was asked: "For each of the following transportation modes, indicate 3 adjectives that characterize them the best: The car is: 1)________ 2)________ 3)________ The train is: 1)________ 2)________ 3)________ etc." After this survey, a second online survey was conducted to collect information on how individuals would situate the adjectives reported in the first survey (e.g. stressful, relaxing, full, etc.) on a scale of comfort. For example, respondents were ask to rate adjective 'relaxing' on a scale from -2 to 2, with -2 indicating a total discomfort and 2 indicating a total comfort. In addition to this, they had to report some socio-economic information (languages spoken at home or work, mother tongue, level of education, etc.). This project has two goals: 1. Model of the effect of the socio-economic information of the respondents of the second survey on their ratings of the adjectives. 2. Integrate the model developed in 1. into a discrete choice model to explain the transportation mode preferences.

Measuring Passenger Satisfaction using AirS@t Survey, Lidija Stankovikj (Mathematics)

Supervision: Bilge Atasoy, Aurélie Glerum
M1nd-set is an international market research agency specialized in air travel surveys and research. The company conducts regular passenger satisfaction surveys among the major fullservice airlines on different international market areas. M1nd-set manages reasonable passenger response rates and over a third of their survey is administered on business-class travelers who value passenger service. At present, AirS@t survey captures the passenger satisfaction levels for different parameters, such as waiting times for check-in, boarding and in-flight services, staff friendliness, seat comfort, in-flight entertainment, meals, etc., that are perceived to drive the overall satisfaction of flying with a particular airline company. M1nd-set uses a specific method of calculating weights of these parameters, in the order of importance, and arriving at overall airline satisfaction levels. However we see some scope in applying more advanced scientific models to this data to gain a deeper perspective on the relative significance of these parameters. In addition, it is critical to understand if higher satisfaction levels with a particular carrier are actually translating into increased demands and thus increased revenues. This could also mean that we can test the sufficiency of the currently captured parameters and if there are some additional parameters that could be silently driving the demand. M1nd-set is seeking fresh, innovative and out-of-the-box ideas to analyze the data mine at hand. They are willing to give access to the data base (under the umbrella of the enclosed NDA) to the student who brings an interesting research idea. Ideally the outcome of this research / analysis should be presented to airlines on conference(s) and/or published. This project will be composed of the following stages: 1. Understanding basic airline industry domain, various players and AirS@t survey in that perspective 2. Literature review and discussion on new ideas 3. Preliminary data analysis 4. Application of fresh methodologies for data analysis, such as using Discrete Choice Models for analysis 5. Inclusion of additional questions on the survey that could provide new insights 6. Final presentation and report Project will commence around mid February and would continue for about 4 1/2 months

Battery life modelling, François Anken (Mathematics)

Supervision: Aurélie Glerum
In a context where electric vehicles are going to be released soon on the market, a high importance is given to the analysis of the degradation of their batteries. A key aspect of this research is to identify the factors that are responsible for a fast battery degradation, in order to give drivers advices on a battery-friendly driving. The aim of the project is two-fold: 1) Refine an existing model of the state of charge of the battery, in order to identify which are the factors explaining the battery discharge and how they affect it. 2) Analyze the impact of different driving patterns and other factors on battery degradation. The student will have to get familiar with an existing battery life model owned by ZEM.

Integrating the latent attitudes into mode choice, Lidija Stankovikj (Mathematics)

Supervision: Bilge Atasoy, Aurélie Glerum
In the classical mode choice modeling we have the modal attributes like time and cost, and the socio-economic information as explanatory variables. However there are unobservable variables like attitudes, perceptions, lifestyle etc. which are effective in travel behavior. In this project aim is to come up with integrated choice models including these latent variables.

Analysis of Electric Vehicle Data, Parmeet Singh Bhatia

Supervision: Aurélie Glerum
The project aims to apply statistical analytics and basic mathematical techniques to analyze a unique data set of electric vehicle usage, and a cutting edge battery life model. The student will analyze the impact of different driving patterns and other factors on battery degradation � a key question facing the transportation industry today. The student will be exposed to the latest developments in mobility and electric vehicle development, and will have constant access to supervisors that will guide him / her to better understand the technical and industrial context of the project. The student will have great autonomy in choosing the mathematical and analytic techniques he/she is familiar with to run simulations, stress the data sets, and incorporate new analytical models as necessary.
