Measuring Passenger Travel Time Reliability using Smartcard Data

Bagherian, M. (author), Cats, O. (author), van Oort, N. (author), Hickman, M (author)

Service reliability is a key performance measure for transit agencies in increasing their service quality and thus ridership. Conventional reliability metrics are established based on vehicle movements and thus do not adequately reflect passenger’s experience. In the past few years, the growing availability of smart card data allows shifting the...

Urban Demand Responsive Transport in the Mobility as a Service Ecosystem: Its Role and Potential Market Share

Alonso González, M.J. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)

Mobility as a Service (MaaS) is entering the transportation market. MaaS aims at the full integration of the existing transportation services and it offers tailored mobility packages to the user. In MaaS ecosystems, on-demand services play an important role as complement to public transport due to their flexibility. However, to date, most...

Performance Assessment of Fixed and Flexible Public Transport in a Multi Agent Simulation Framework

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The emergence of innovative mobility solutions that offer flexible transport services, is changing the way urban public transport systems will be designed. Such mobility solutions offer on demand transport services and hence can solve the problems inherent with traditional line based and schedule based public transport systems. It is essential...

A robust transfer inference algorithm for public transport journeys during disruptions

Yap, M.D. (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

Disruptions in public transport have major impact on passengers and disproportional effects on passenger satisfaction. The availability of smart card data gives opportunities to better quantify disruption impacts on passengers’ experienced journey travel time and comfort. For this, accurate journey inference from raw transaction data is required...

Investigating Potential Transit Ridership by Fusing Smartcard Data and GSM Data

de Regt, K.L. (author), Cats, O. (author), van Oort, N. (author), van Lint, J.W.C. (author)

The public transport industry faces challenges in catering to the variety of mobility patterns and corresponding needs and preferences of passengers. Travel habit surveys provide information on overall travel demand as well as its spatial variation. However, that information often does not include information on temporal variations. By applying...

Passenger Route Choice and Assignment Model for Combined Fixed and Flexible Public Transport Systems

Narayan S., Jishnu (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

The recent technological innovations have given rise to innovative mobility solutions. Public transport systems combining such services need novel models for the design of services. We develop a multimodal route choice and assignment model for combined use of line/schedule based public transport systems (fixed public transport) and demand...

Value of Reliability for the Waiting Stage, In-vehicle Stage and Transfer Stage of Demand Responsive Transport (DRT) Services

Alonso González, M.J. (author), Hoogendoorn-Lanser, S. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)

On-demand modes are playing an ever-increasing role in urban transportation. In<br/>particular, Demand Responsive Transit (DRT) (shared on-demand modes such as<br/>shared ride-hailing and microtransit) can complement scheduled public transport<br/>thanks to their collective nature. These services offer flexible and convenient<br/>mobility: they...

Assessing disruption management strategies in rail-bound urban public transport systems from a passenger perspective

Roelofsen, Dennis (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

This paper provides a framework for generating and assessing alternatives<br/>in case of disruptions in rail-bound urban public transport systems,. The proposed<br/>framework considers the passenger perspective as well as the operator perspective,<br/>for the often-used measures of detouring and short-turning. An application of the<br/>framework...

The Potential of Demand-Responsive Transport as a Complement to Public Transport: An Assessment Framework and an Empirical Evaluation

Alonso González, M.J. (author), Liu, T.L.K. (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

Demand-responsive transport (DRT) services (collective on-demand services, such as shared ridesourcing and microtransit) offer a collective flexible travel alternative that can potentially complement fixed transit (FT). The combination of an on-demand and line-based service holds the promise of improved mobility and increased service coverage...

Willingness to share rides in on-demand services for different market segments

Alonso González, M.J. (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn-Lanser, S. (author), Hoogendoorn, S.P. (author)

The impact of on-demand urban transport services on traffic reduction will depend on the willingness to share (WTS) of individuals. However, the extent to which individuals are willing to share remains largely unknown. By means of a stated preference experiment, this study analyses the WTS of respondents by comparing their preferences towards...

Where shall we sync? Clustering passenger flows to identify urban public transport hubs and their key synchronization priorities

Yap, M.D. (author), Luo, D. (author), Cats, O. (author), van Oort, N. (author), Hoogendoorn, S.P. (author)

Minimizing passenger transfer times through public transport (PT) transfer synchronization is important during tactical planning and real-time control. However, there are computational challenges for solving this Timetable Synchronization Problem (TSP) for large, real-world urban PT networks. Hence, in this study we propose a data-driven,...

Combining Speed Adjustment and Holding Control for Regularity-based Transit Operations

Imran, Aishah Mahyarni (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author), Van Der Pot, Pieter (author)

Vehicle bunching often occurs in high-frequency transit systems leading to deterioration of service reliability. It is thus necessary to control vehicles during operations. Holding control is a common solution for this situation, but it may result in longer vehicle running times. Speed adjustments can contribute to more regular operations...

Passenger Travel Time Reliability for Multimodal Public Transport Journeys

Dixit, M. (author), Brands, T. (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)

Urban transit networks typically consist of multiple modes and the journeys may involve a transfer within or across modes. Therefore, the passenger experience of travel time reliability is based on the whole journey experience including the transfers. Although the impact of transfers on reliability has been highlighted in the literature, the...

Robust Control for Regulating Frequent Bus Service: Supporting the Implementation of Headway-Based Holding Strategies

van der Werff, Ellen (author), van Oort, N. (author), Cats, O. (author), Hoogendoorn, S.P. (author)

Reliability is a key determinant of the quality of a transit service. Control is needed to deal with the stochastic nature of high-frequency bus services and to improve service reliability. This study focuses on holding control, both schedule- and headway-based strategies. An assessment framework is developed to systematically assess the effect...
