Introduction Mode Choice modelling
◦ Third stage in 4-stage transport modelling
Data : Household travel survey ◦ Variable groups: Socio-economic, Level of Service, Demographic
Location: Windsor, ON◦ High level of vehicle ownership (automotive capital of Canada)◦ Spread out geographically◦ No transit services to suburbs-Lasalle, Amherstberg, Lakeshore etc
Modelling technique: Multinomial Logit model
Software tool: NLOGIT5 (Student version)

ObjectiveFrom the given data, find the variables which have a significant impact on the choice of mode for work-trips and analyse the effect of the variables (positive/negative) on the choice of each mode using a discrete choice method.

Literature Review[Ding et al., 2014 (Exploring the influence of built environment on tour-based commuter mode choice: A cross-classified multilevel modeling approach)]
◦ Distance of home zone from the work location is significant and has a positive effect on auto mode◦ Employment density at work location and population density at home location both significant, but
employment density at work location more so◦ Travel time has a negative impact on auto mode◦ Highly mixed land-use living areas encourage the use of transit for work while mixed land use at
work location not significant[Yong Le Loo et al., 2015 (Transport mode choice in South East Asia: Investigating the relationship between transport users’ perception and travel behaviour in Johor Bahru, Malaysia)]
◦ Variables having a positive effect on public transport use were location of residence, students studying in Singapore, education-trade and technical skills institution and education-post secondary institution
◦ Variables having a negative impact were, gender-female, age(45-54), employed in Johor Bahru and employed in Singapore

Literature Review[Owen A., 2013 (Modeling the commute mode share of transit using continuous accessibility to jobs)]
◦ Transit mode share was found to decrease with increase in household income, increase in population of white, non-hispanics and vehicle ownership.
◦ Household size and education had a negative association with transit ridership.
[de Palma and D Rochat, 2000 (Mode choices for trips to work in Geneva: an empirical analysis)]◦ Variables having a positive impact on number of auto trips: Number of years of commuting,
cross-border travel, duration of daily congestion, weather, female, size of the household, children going to school, young people with age less than 30years
◦ Variables having a negative impact on number of auto trips: Travel time, travel cost, flexible work hours, frequency of congestion, senior people with age more than 50 years, employed in top management, education level

Literature Review [M El-Sayed El-Bany et al., 2014 (Policy sensitive mode choice analysis of Port-Said City, Egypt)]
◦ High income has a positive effect on car/taxi use◦ Out of vehicle travel time has larger impact (negative) than in-vehicle travel time on auto use
[J Zhou, 2012 (Sustainable commute in a car-dominant city: Factors affecting alternative mode choices among university students)]◦ Possessing a discounted transit pass has a positive effect on alternative mode use◦ Commute distance is positively related to carpool. Distance not significant for walking, biking
or transit modes◦ Gender, education level and age significant and positive co-relation to alternate modes
