The rationales that underlie modal practices

Encouraging a modal shift from individual transportation to less polluting modes such as public transport, walking and cycling, is now a key recommendation of the UN to reach the goals set by the Paris Agreement. Achieving this ambitious goal requires a de ...

Modeling lane changing and lane choice using naturalistic data from a swarm of drones

The pNEUMA dataset is the result of a unique field experiment using a swarm of ten drones flying over the central district of Athens, Greece. Using this newly available dataset, this paper focuses on two directly related topics: i) lane changing and ii) la ...

Assessment of the Bus Transit Network: A Perspective from the Daily Activity-Travel Organization of Travelers

Marc-Edouard Baptiste Grégoire Schultheiss

In a context where daily car use is a spontaneous and habitual choice for a wide majority of the population, the quality of the alternatives to individual motorized vehicles is a major factor in encouraging modal shift. The ease of access to public transpo ...

Modeling and optimization of dedicated bus lanes space allocation in large networks with dynamic congestion

Nikolaos Geroliminis, Dimitrios Tsitsokas, Anastasios Kouvelas

Dedicated bus lanes provide a low cost and easily implementable strategy to improve transit service by minimizing congestion-related delays. Identifying the best spatial distribution of bus-only lanes in order to maximize traffic performance of an urban ne ...

Dedicated bus lane network design under demand diversion and dynamic traffic congestion: An aggregated network and continuous approximation model approach

Nikolaos Geroliminis, Mehmet Yildirimoglu

This paper proposes an integrated methodological framework to design a spatially heterogeneous bus route network and time-dependent service headways to serve travel demand that varies over time and space. Travelers choose to use either the transit mode or ...

Empirical analysis of large-scale multimodal traffic with multi-sensor data

Nikolaos Geroliminis, Nan Zheng, Hui Fu

Recent advances in the network-level traffic flow modelling provide an efficient tool for analyzing traffic performance of large-scale networks. A relationship between density and flow at the network level is developed and widely studied, namely the macros ...

Dynamic lane restrictions on congested arterials

Nikolaos Geroliminis, Paul Richard Anderson

Buses operating in mixed traffic experience problems with delay and travel time variability in peak periods. Numerous transit priority measures are found in the literature but most rely on separating buses from other vehicles. Complete separation such as d ...

Combinatorial optimization of Dedicated Bus Lane layout in urban networks with dynamic congestion

Nikolaos Geroliminis, Dimitrios Tsitsokas, Anastasios Kouvelas

Transit priority based in exclusive right-of-way is a low-cost way of improving transit service by minimizing delays caused by interaction with other vehicles. This effect can increase the share of public transit against private cars in the mode preference ...

Protection Coordination for Reliable Marine DC Power Distribution Networks

Drazen Dujic, Seongil Kim, Gabriele Ulissi

This paper presents demonstration of a protection scheme integrated into marine DC power distribution networks to investigate the coordination between each protection action. The integrated protection scheme is based on three different time-frame protectio ...

An optimization framework for exclusive bus lane allocation in large networks with dynamic congestion

Nikolaos Geroliminis, Dimitrios Tsitsokas, Anastasios Kouvelas

Road space distribution among multiple modes of transport in urban networks has attracted the interest of several researchers and policy planners. Traditionally, these problems are solved by ignoring operational and dynamic characteristics of multi-modal c ...

Modeling and Optimization of Dedicated Bus Lane network design under dynamic traffic congestion

Nikolaos Geroliminis, Dimitrios Tsitsokas, Anastasios Kouvelas

Collective transport has been seen for long as a proper solution to fight congestion. While collectivity has been successful with respect to subways, it is not the norm in road traffic. Dedicated Bus Lanes (DBL) have been proposed as a measure to reduce th ...

Hybrid Model Predictive Control of Bus Transport Systems

Nikolaos Geroliminis, Isik Ilber Sirmatel

Schedule instability adversely affects the performance of bus transport systems. Bus bunching and similar irregularities decrease quality of bus services and increase travel times. In this regard, bus system management schemes are of high importance. Motiv ...

Continuous structural health monitoring for short and medium span bridges

Ayaho Miyamoto

In this paper, although there are some useful monitoring methods for short and medium span(10-20m) bridges based on the qualitative or quantitative information, mainly two advanced structural health monitoring systems are described to review and analyses t ...

Hybrid Modeling and Predictive Control of Bus Transport Systems

Nikolaos Geroliminis, Isik Ilber Sirmatel

Bus operations, due to their unstable nature, are inefficient when left to their own devices. Irregularities such as bus bunching lead to loss of time and decrease bus service quality. Development of bus transport system management schemes to avoid bus bun ...

Dynamical Modeling and Predictive Control of Bus Transport Systems: A Hybrid Systems Approach

Nikolaos Geroliminis, Isik Ilber Sirmatel

Bus operations, due to their unstable nature, are inefficient when left uncontrolled with respect to retaining headways. Irregularities such as bus bunching lead to loss of time and decrease bus service quality. Development of bus transport system manageme ...

A three-dimensional macroscopic fundamental diagram for mixed bi-modal urban networks

Nikolaos Geroliminis, Nan Zheng, Konstantinos Ampountolas

Recent research has studied the existence and the properties of a macroscopic fundamental diagram (MFD) for large urban networks. The MFD should not be universally expected as high scatter or hysteresis might appear for some type of networks, like heteroge ...

Effects of hard shoulder lanes configuration on driver’s behaviour

André-Gilles Dumont, Jade Chapoton

Nowadays, reassignments of hard shoulders into traffic lanes are spreading across Europe. This traffic management measure allows to respond to the growing saturation of high-capacity roads.In Switzerland, the first stretch to be equipped in such a way was ...

Measuring the Effects of Economic Crisis on Users' Perceptions of Public Transport Quality

Dimitrios Efthymiou

Research was conducted to measure the effects of the economic crisis on public transport quality, user satisfaction, and transit demand. The survey used in this research extended a research effort that began in 2008; the survey aimed to analyze the variabi ...

The School Bus Problem on Trees

Laura Sanità, Adrian Aloysius Bock

The School Bus Problem is an NP-hard vehicle routing problem in which the goal is to route buses that transport children to a school such that for each child, the distance travelled on the bus does not exceed the shortest distance from the child's home to ...

Public Urban Transport, Mobility Patterns and Social Exclusion : The Case of Santiago de Chile

Regina Witter

What are the social impacts of a new, less efficient public transport system in a city that is known for its inequality concerning access to daily activities and participation in urban life? More precisely, what are the implications of a re-regulated trans ...
