Unsupervised Learning for Public Transport Delay Pattern Analysis

Cheng, Y. (author), Krishnakumari, P.K. (author)

To analyze inherent and diverse patterns within line-based public transport daily delay occurrences, we introduce a data-driven exploratory analysis focused on the spatial-temporal distribution of these delays. Our approach relies on the utilization of the image pattern recognition technique and k-means clustering algorithm. We extract daily...

Improving Traffic Efficiency With Lane Guidance Based on Desired Speeds

Mahajan, N. (author), Hegyi, A. (author), Hoogendoorn, S.P. (author), van Arem, B. (author)

Drivers initiate a discretionary lane change when they perceive an anticipated improvement in their own driving condition from moving to another lane. However, such a lane change can slow down other vehicles on the target lane, and even worse initiate a disturbance. In this work, we argue that the blocking effect triggered by individual lane...

Understanding preferences for mobility-on-demand services through a context-aware survey and non-compensatory strategy

Dubey, S.K. (author), Cats, O. (author), Hoogendoorn, S.P. (author)

The potential lack of realism in stated-preference surveys is particularly acute in contexts where disaggregate real-world data is challenging to obtain. Mobility-on-Demand (MOD) services present one such context. The MOD context is unique due to factors such as service reliability (difference in stated vs. actual travel and waiting time) and...

The effects of three environmental factors on building evacuation time

Kinkel, E. (author), van der Wal, C.N. (author), Hoogendoorn, S.P. (author)

Building fires can be considered a risk to the health and safety of occupants. Environmental factors in building fires might affect the speed of an evacuation. Therefore, in this study participants (N = 153) were tested in an experimental design for the effects of (1) a fire alarm, (2) darkness and (3) the use of emergency exit signs on...

Hubs for Freight and Passengers?: Exploring the suitability of adding logistics functions to mobility hubs

Chetouani, Israe (author), van Duin, Ron (author), Vleugel, J (author), van Wee, G.P. (author), van Son, C.B.H. (author), Arends, H.H. (author)

In the coming years, cities will have to deal with transportation challenges in terms of accessibility and sustainability. Passenger and freight transport are expected to increase, while the transport sector is a major contributor to greenhouse gas emissions and congestion in cities. Although historically both ecosystems (passenger transport and...

Unprotected Left-Turn Behavior Model Capturing Path Variations at Intersections

Zhao, Jing (author), Knoop, V.L. (author), Sun, Jian (author), Ma, Zian (author), Wang, M. (author)

Path dispersion (the spatial distribution of vehicular paths) is an important feature of traffic flow inside intersections and differs from traffic flow running along traffic lanes at road segment, especially under conflicting movements. The path dispersion reflects the operational features of traffic flow and is related to driving behaviour,...

Bicycle Data-Driven Application Framework: A Dutch Case Study on Machine Learning-Based Bicycle Delay Estimation at Signalized Intersections Using Nationwide Sparse GPS Data

Yuan, Y. (author), Wang, Kaiyi (author), Duives, D.C. (author), Hoogendoorn, S.P. (author), Hoogendoorn-Lanser, S. (author), Lindeman, Rick (author)

Data-driven approaches are helpful for quantitative justification and performance evaluation. The Netherlands has made notable strides in establishing a national protocol for bicycle traffic counting and collecting GPS cycling data through initiatives such as the Talking Bikes program. This article addresses the need for a generic framework to...

Didn’t travel or just being lazy? An empirical study of soft-refusal in mobility diaries

de Haas, M.C. (author), Kroesen, M. (author), Chorus, C.G. (author), Hoogendoorn-Lanser, S. (author), Hoogendoorn, S.P. (author)

In mobility panels, respondents may use a strategy of soft-refusal to lower their response burden, e.g. by claiming they did not leave their house even though they actually did. Soft-refusal leads to poor data quality and may complicate research, e.g. focused on people with actual low mobility. In this study we develop three methods to detect...

Dynamic Geo-Fencing for Polycentric Congestion Management: A Simulation-Based Analysis

Pecorari, N. (author), Rinaldi, M. (author), Hoogendoorn, S.P. (author)

Our cities are growing at an unprecedented pace. The flexible use of metropolitan infrastructures is the key to maintaining, if not increasing, the current quality of life. The combined use of geo-fence technology and connected vehicles can be the tool to achieve this flexibility. In this paper, we take a first step in the evaluation of the...

Travel demand matrix estimation for strategic road traffic assignment models with strict capacity constraints and residual queues

Brederode, L.J.N. (author), Pel, A.J. (author), Wismans, Luc (author), Rijksen, Bernike (author), Hoogendoorn, S.P. (author)

This paper presents an efficient solution method for the matrix estimation problem using a static capacity constrained traffic assignment (SCCTA) model with residual queues. The solution method allows for inclusion of route queuing delays and congestion patterns besides the traditional link flows and prior demand matrix whilst the...

Microscopic Traffic Modeling Inside Intersections: Interactions Between Drivers

Zhao, J. (author), Knoop, V.L. (author), Wang, M. (author)

Microscopic traffic flow models enable predictions of traffic operations, which allows traffic engineers to assess the efficiency and safety effects of roadway designs. Modeling vehicle trajectories inside intersections is challenging because there is an infinite number of possible paths in a two-dimensional space, and drivers can...

Ship behavior during encounters in ports and waterways based on AIS data: From theoretical definitions to empirical findings

Zhou, Y. (author), Daamen, W. (author), Vellinga, T. (author), Hoogendoorn, S.P. (author)

Currently, the research on ship behavior during encounters focuses on evasive behavior during specific situations with existing risks of collision. However, the preliminary selection of encounters to refine the presented ship behavior is biased. To obtain a full understanding of all ship behavior during different encounters in ports and...

Design and classification of tradable mobility credit schemes

Provoost, J.C. (author), Cats, O. (author), Hoogendoorn, S.P. (author)

The ongoing research on tradable credit schemes (TCS) in mobility has captured the attention of policymakers, authorities and academics. Even though several studies have demonstrated the potential of such schemes, key policy design aspects that are relevant for real world implementation have been overlooked. There exists insofar no blueprint...

“Who can I ask for help?”: Mechanisms behind digital inequality in public transport

Digitalisation in public transport has become pervasive over the past decade, especially in urban areas. While it benefits many, it also leaves some behind. Previous research shows that older adults, people with a lower education level, people with impairments and people with a migration background are more likely to be negatively impacted by...

Service design and frequency setting for the European high-speed rail network

Grolle, J. (author), Donners, Barth (author), Annema, J.A. (author), Duinkerken, M.B. (author), Cats, O. (author)

High-speed rail (HSR) is frequently seen as a promising alternative for long-distance travel by air and road, given its environmental advantages whilst offering a competitive level of service. However, a European HSR-network is yet to be realised, with the current state amounting to a patchwork of poorly connected subnetworks. Consequently,...

Traffic flow theory and modelling

Knoop, V.L. (author), Hoogendoorn, S.P. (author)

When do traffic jams emerge? Can we predict, given certain demand levels, when queuing will occur, how long the queues will be, how they will propagate in space and time, and how long it takes for the congestion to resolve? Why does an overloaded traffic network underperform? This chapter gives a basic introduction in traffic flow theory which...

As digitalisation is making its way into public transport (PT) services, policy approaches to ensure that such services remain inclusive are at best fragmented, at worst inexistant. This study pieces together existing initiatives and lessons learnt in the transport sector itself, and takes inspiration from other fields with a more mature...
