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

Nikolaos Geroliminis, Anastasios Kouvelas, Dimitrios Tsitsokas

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 ...

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

Nikolaos Geroliminis, Nan Zheng

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

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 ...

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

Nikolaos Geroliminis, Anastasios Kouvelas, Dimitrios Tsitsokas

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 ...

Electrification of urban mobility: The case of catenary-free buses

Michel Bierlaire, Riccardo Scarinci

Electric mobility is now a reality, and services based on electric vehicles, such as electric car-sharing and electric buses, are becoming part of urban mobility. These new modes bring new challenges for the design and operations of the systems that requir ...

Reducing the Energy Consumption of Electric Buses With Design Choices and Predictive Driving

Francesco Baldi

Transportation electrification is increasing and recently-more focus has been directed on heavy vehicles and especially on city buses. Battery electric buses are inherently more energy efficient than diesel buses and the efficiency can be further increased ...

A systematic analysis of multimodal transport systems with road space distribution and responsive bus service

Nikolaos Geroliminis, Nan Zheng

A smart design of transport systems involves efficient use and allocation of the limited urban road capacity in the multimodal environment. This paper intends to understand the system-wide effect of dividing the road space to the private and public transpo ...

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 ...

Cost-Benefit Analysis of Electric Bus Fleet with Various Operation Intervals

Francesco Baldi

Electric buses are particularly suitable for city and suburban routes due to zero local exhaust and noise emissions. The operation schedule interval defines the charging power, bus fleet size and total cost of ownership of a bus. We propose a novel cost-be ...

Continuous structural health monitoring for short and medium span bridges

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 ...

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 ...

Methods and systems for noise resilient, pin-efficient and low power communications with sparse signaling codes

Mohammad Amin Shokrollahi, Seyed Armin Tajalli, Harm Cronie

In bus communications methods and apparatus, a first set of physical signals representing the information to be conveyed over the bus is provided, and mapped to a codeword of a sparse signaling code, wherein a codeword is representable as a vector of a plu ...

Aseba Meets D-Bus: From the Depths of a Low-Level Event-

Francesco Mondada, Stéphane Magnenat

The robotics research community has clearly acknowledged the need of open and standard software stacks to promote reuse of code and developments. However, to date no particular project has prevailed. We suggest that one possible reason for this is that mos ...
