AbstractThis paper proposes a multilane traffic flow model based on the notions of conservation laws in Lagrangian coordinates. Both the mathematical formulation and the graphical representation are provided. A logit choice model is applied to describe drivers lane choice probability. The lane chang...

This paper proposes a stochastic variant of the stable matching model from Rasulkhani and Chow [1] which allows microtransit operators to evaluate their operation policy and resource allocations. The proposed model takes into account the stochastic nature of users' travel utility perception, resulti...

Against the backdrop of the expansion and densification of metropolitan areas around the world and the recent evolutions in logistics (such as demand-driven supply chain practices), the traffic and environmental impact of urban freight movements is a significant concern. A small share of goods vehic...

Autonomous vehicles (AVs) will impact roadway safety, congestion, mode splits, trip distances, and air quality. We estimate the net social benefits of each AV to be nearly $4,000 per year, thanks to crash savings, travel time reductions, and parking benefits. This seminar will examine the design & r...

The increasing use of the private vehicles makes it increasingly fundamental to understand how to induce users to prefer public transport. In this regard, studying the quality of public transport and the methods to increase them is central. There are several factors involved in the definition of the...

This paper proposes a model for charge scheduling of electric vehicles in last-mile distribution that takes into account battery degradation. A mixed integer linear programming formulation is proposed that minimizes labor, battery degradation and time-dependent energy costs. The benefit of implement...

Free floating shared electric vehicles have the potential to contribute to a zero-emission urban transport system. In comparison to station based car sharing (one or two-way), the vehicle can be left anywhere within a given area instead of at designated stations. This gives the user more flexibility...

The development of new more efficient freight transportation services requires in depth understanding of the engaged stakeholders behavior. Simulation Games (SG) have been used to study decisions and raise awareness over complex transport problems. This paper investigates the possibility of applying...

Shared autonomous vehicles (SAV) are expected to become part of mobility on-demand systems in the near future. The vehicles’ ability to move autonomously has the potential to change the way transportation is perceived. For instance, a system with autonomous vehicles can be used by persons without ...

Automated driving will trigger disruptive changes in the transportation system. Automated sharing and pooling options instead of private ownership are broadly discussed because of their possible contributions to climate change mitigation and sustainability. Despite the growing amount of literature o...

Traffic performance has many positive and negative consequences to the environment and society. These external effects are ever more often considered in the traffic system planning and administration. Desired effects of traffic can be thought as traffic performance policies. It is also possible to s...

Autonomous vehicles (AVs) occupy a crucial part of the emerging mobility. Currently, the potential impacts of self-driving fleets are of great interest to public bodies and authorities. The impact is studied in pilots, but these still have a limited scope, therefore also simulation studies are neces...

In this paper, we propose an optimization model to select the charging locations of an automated electric taxi (AET) system. The service provided by this AET system is a seamless door-to-door service connected to the train station, which helps improve the last mile transport. We individualize the ve...

Automated vehicles (AVs) are gradually entering our roadway system and self-driving buses are under development for trials and implementation in ordinary (mixed) traffic. Self-driving (mini)buses or Shared Automated Vehicles (SAVs) are a new transport mode, completely automated, with no steering whe...

Accurately modeling the realistic and unstable traffic dynamics of human-driven traffic flow is crucial to being able to to understand how traffic dynamics evolve, and how new agents such as autonomous vehicles might influence traffic flow stability. This work is motivated by a recent dataset that a...

The number of personal cars is expected to rise at a rapid rate, particularly in developing countries, such as China and India. These increases will hamper the global effort to reach the climate target set by the Paris Agreement as most of these vehicles will be fossil-fuel powered. Urban carsharing...

Last mile delivery is seen as the most expensive part of the supply chain, and causes significant external effects (e.g. pollution, land use, noise). Therefore, much research has been devoted to finding alternative vehicles to deliver parcels such as drones and cargo bicycles and to finding alternat...

Many alternative approaches to achieve improvement in transportation system sustainability are continuously being proposed. The sheer number and diversity of suggested approaches available in the literature is overwhelming. Decision makers, consequently, need support in the fair and comprehensive ev...

Cities are estimated to have a 70% contribution to global greenhouse gas emissions. This makes urban sustainability monitoring necessary, but are urban sustainability monitoring frameworks applicable to cities of all sizes? And do they offer a consistent overview of the sustainability status of core...

Despite its relatively small size, Luxembourg City is facing major challenges in terms of traffic congestion (33h/person/year spent in traffic congestion according to the INRIX 2017 Global Traffic Scorecard), primarily caused by an important share of cross-border commuters driving more than 35km on ...

As automated vehicles become increasingly common on the road, the call for an appropriate preparation for its drivers is becoming more urgent. Expert opinions and insights have been acquired via a focus group discussion with eleven Dutch driving examiners to assist in inventorying what types of prep...

The main purpose of this work is to develop a single vehicle noise emission model that uses speed as input variable and returns as output a parameter directly referable to the noise source, namely the source sound power level (Lw). The model was tested on three light-duty vehicles with different mot...

In this paper we propose a novel observer-based method for anomaly detection in connected and automated vehicles (CAVs). The proposed method utilizes an augmented extended Kalman filter (AEKF) to smooth sensor readings of a CAV based on a nonlinear car-following motion model with time delay, where t...

Although the electrification of transportation can bring long-term sustainability, increasing penetration of Electric Vehicles (EVs) may cause more congestion. Inappropriate deployment of charging stations not only hinders the EVs adoption but also increases the total system costs. This paper attemp...

Is a roundabout still a good solution in the era where intelligent intersection control using vehicle connection (i-TLC), is in upswing? To answer this question, the capacity of i-roundabouts, where the infrastructure communicates with the vehicles (I2V), is determined analytically. The roundabouts ...

This paper presents a new agent-based model able to simulate innovative flexible demand responsive transport services, specifically thought to solve the last-mile problem of mass rapid transit. This is particularly needed in areas characterized by insufficient transit supply and lower sprawled deman...

Most V2X applications/services are supported by the continuous exchange of broadcast messages. One of the main challenges is to increase the reliability of broadcast transmissions that lack of mechanisms to assure the correct delivery of the messages. To address this issue, one option is the use of ...

Metropolitan authorities continue to seek programs and initiatives to reduce emissions in their jurisdictions. It has been shown that transitioning from fossil fuel to electric propulsion of transportation can help realize this goal. However, the current market penetration of electric vehicles (EVs)...

Many railway companies are experimenting with Automatic Train Operation (ATO) and most of them are aiming at grade of automation (GoA) level 2. This is the automation level whereas the train is driven automatically, and the driver is still fully responsible and also performing other tasks. The field...
