TRB 2023 Research Poster. Title: Guiding Principles for Planning Bus Transit Networks of Integrated On-demand and Scheduled Services. Authors: Alaa Itani, Willem Klumpenhouwer, Brendon Hemily, Amer Shalaby.

This research presents guidance on integrating on-demand transit (ODT) with conventional bus systems at the strategic and tactical planning processes. It is based on industry interviews, scholarly and non-scholarly research material, and an expert workshop hosting transit agencies in Canada that operate ODT. The results showed that there isn't a single recipe that works for all transit networks when it comes to integrating ODT with the fixed-bus systems.

Typical performance measurements of public transit operations make use of vehicle-based data such as automated vehicle location data, or passenger-based data at specific fare collection points. Ideally, the performance of a transit system from a reliability and passenger experience should be measured through individual passenger journeys. The growing prevalence of smartphones provides one potential source for this analysis, as passive methods such as WiFi, cellular, and Bluetooth connection data allow us to observe devices as they move throughout the system, measuring various aspects of customer experience and reliability, including methods for detecting train arrivals at platforms, estimating wait times, and analyzing origin-destination travel time variation.

Rational Inattention in Discrete Choice Models: Estimable Specifications with Empirical Applications of RI-Multinomial Logit (RI-MNL) and RI-Nested Logit (RI-NL) Models

TRB 2023 Research Poster. Title: Rational Inattention in Discrete Choice Models: Estimable Specifications with Empirical Applications of RI-Multinomial Logit (RI-MNL) and RI-Nested Logit (RI-NL) Models. Author: Khandker Nurul Habib, PhD, P.Eng.

As opposed to the fully informed choice-making assumption in classical discrete choice models, the theory of Rational Inattention (RI) in discrete choice modelling has been recently proposed in the literature. Matějka and McKay (2015) proposed the RI-multinomial logit (RI-MNL), and Fosgerau et al. (2020) proposed the RI-nested logit (RI-NL) model. These models consider that choice makers are bayesian agents with prior probabilities of choices and process any further information at the cost of an information processing cost to have the updated/posterior choice probabilities. However, the proposed RI-MNL and RI-NL models are theoretical formulations without any estimable empirical specifications. This paper proposes econometric formulations of RI-MNL and RI-NL models that are estimable using classical maximum estimation methods and suitable for revealed crossectional choice data. The proposed models are estimated for commuting mode choices in the Greater Toronto and Hamilton Area (GTHA) using data from a household travel survey conducted in the region. Empirical investigation reveals that the induction of RI in the classical discrete choice models (MNL and NL) improved the model fit by large margins. While just scale parameterization in classical MNL and NL does not make a better model, the scale parameterization better captures the choice heterogeneity within the RI framework. Between the RI-MNL and RI-NL, the RI-NL is proven to be the best. The RI-NL model can capture asymmetric (between increasing and decreasing values) elasticities of choice attributes.

TRB 2023 Research Poster. Title: Fusing Repeated Cross-sectional Revealed Preference Datasets based on Rational Inattention Theory: Accounting for Changing Modal Preferences. Authors: Sanjana Hossain, Khandker Nurul Habib.

To address the methodological limitation of cross-sectional studies and the data constraints of longitudinal/panel studies, this research presents a model-based method to fuse repeated cross-sectional travel survey data based on the theory of Rational Inattention in discrete choice modelling. In the proposed framework, older cross-sectional data is used to model the prior probability of choice alternatives, and more recent cross-sectional data is used to capture conditional heterogenous choices. The fusion method is theoretically more robust and computationally less burdensome than existing data pooling techniques.

Authors: Sanjana Hossain, Patrick Loa, Kaili Wang, Sk. Md. Mashrur, Alireza Dianat, Khandker Nurul Habib.

This research demonstrates the feasibility of fusing a “core” household travel survey with three specialized “satellite” surveys to evaluate the impacts of COVID-19 on passenger travel demand in the Greater Toronto Area. The study uses a non-parametric implicit data fusion method to generate multiple synthetic datasets that contain observed travel diaries and socioeconomic attributes of the trip-makers from the core survey, along with imputed attitudinal statements based on the satellite surveys. The results highlight the ability of the method to sufficiently reproduce the distribution of the attitudinal variables and the ability of the imputed variables to support the estimation of an advanced econometric model.

We compared both the on-time performance and transit-focused Twitter sentiment of public transit before and after a major service change in Calgary, Canada. We found that for adjusted routes, performance decrease corresponded with a decrease in the sentiment about specific routes, and a connection exists between low-performing sections of a route and the negative sentiment expressed online.

In this study, we developed a mode choice model using a novel structure of deep neural network. The model achieved high prediction accuracies, and was used to examine factors influencing people's mode choice decision, particularly the use of ride-sourcing services. It can also be utilized to understand the pandemic’s short- and long-term impacts on rider-sourcing utilization. We discovered that people's perceived safety of using ride-sourcing services and willingness to spend time outside are determining factors.
