DC trolleygrids as sustainable, multi-functional, and multi-stakeholder electrical infrastructures: Thinking outside of the bus

Electricity grids are increasingly congested as the world moves toward a sustainable, electrified future. Expanding and upgrading these infrastructures is costly and challenging on a technical and administrative level and even redundant when considering that some sub-parts of these grids, such as electric transportation networks, are massively...

Circular economy implementation in railway systems beyond net zero

Built Environmental Correlates of Cycling Accidents Involving Fatalities and Serious Injuries in London, UK

Introduction: Approximately 2,552 individuals were killed or seriously injured through cycling accidents in the Greater London Area between 2010 and 2015. The purpose of this study is to investigate a wide range of built environmental correlates of cycling accidents resulting in KSI so that we can identify potential areas for targeted...

A proposal for an improved transportation model in CityGML

CityGML, an OGC standard, is an open data model for virtual 3D city models and includes buildings, roads, terrain, water bodies, etc. While many modules are well-developed (eg buildings, bridges, tunnels), the transportation model is, based on our consultations with various government agencies and municipalities, not sufficient for most...

Exploring challenges and solutions for container transportation using rail: A modelling and simulation gaming study

Rail is a cost-effective and environment friendly freight transport modality when used efficiently. Stakeholders around Dutch ports are discouraged to choose rail due to uncertain train schedules and the dispersed nature of freight flows across terminals in the port. To understand the challenges and opportunities of freight transport using rail,...

Towards a line-of-sight, implementation of performance measurement by road agencies: A European and Western Australian perspective

This paper is the result of an international, explorative study of the alignment of government and road authority goals from different European countries and Western Australia. The goal of the study is to advance the understanding of the development of performance management of road agencies. Agencies around the world are using performance...

An Activity-Based Multimodal Model Structure to assess Transportation Management Strategies for Urban Emergencies

There are many kinds of disasters that can severely impact the transportation system of an urbanized region. Transportation authorities therefore need to develop management strategies to adequately deal with such emergencies. In this paper, we discuss the structure of a simulation model that can be used to assess a candidate strategy. We model...

Travel time reliability during evacuation: The impact of heterogeneous driving behavior

Earlier studies have shown that driving behavior differs strongly in emergency conditions compared with behavior in normal traffic conditions. In this paper, these findings are followed up with an investigation of how these differences in driving behavior affect travel time reliability. In particular, the focus is on the effect of relatively...
