One of the goals of this research is to arrive at an implementation of a CAN-bus that can be used for lab exercises in regular student courses. In this paper, an overview is given of our basic ideas concerning the CAN concept and its application to the control of a manufacturing system. This system consists of two robots, a milling machine and some transportation means. In this system, every workstation will have its own CAN controller. The concept consists of a specially designed hardware structure, embedded software for the protocol and initialisation and a high level production environment, that makes it possible to configure a production system in an easy way.

This report summarizes the work done by Thematic Working Group 4 (TWG4) on “Procurement and Tendering” for e-bus deployment. It further analyses the various Good Practices collected by project partners with a reference to the above aspects. This report takes the policy learning one step further and sheds light on regional similarities and differences in practices that have been found functional and worth spreading.

The Interreg Europe eBussed project supports the transition of European regions towards low carbon mobility and more efficient transport. The regions involved are Turku (Finland), Hamburg (Germany), Utrecht (The Netherlands), Livorno (Italy), South Transdanubia (Hungary) and Gozo island in Malta. It promotes the uptake of e-busses in new regions and supports the expansion of existing e-fleets. Within the project, there are four thematic working groups formed that aim at delivering a best practices report and policy recommendations to be used in the partner regions. Thematic Working Group 4 (TWG4) focusses on the topics of Procurement, Tendering and Costs of e-busses. As a starting point for TWG4, the value chain for e-bus public transport per region has been mapped. By mapping how the value chain for e-bus public transport works and defining the nature of the issues, problems or maybe challenges per region can be better understood.

This research was commissioned by the province of Groningen. The province of Groningen asked the question how the quality her bus stop data could be improved.The province of Groningen is ultimately responsible for public transport. The public transport bureau is set up in 2005 to arrange bus transportation. The management of the bus stops, however, is in the hands of the regional and local authorities. The province manages the bus stops along the provincial highways The municipalities are responsible for the other bus stops in the province. The staff who manage the bus stops are called road authorities. Also on this domain the County has to do with laws and policies. The province of Groningen states in its strategic Information plan that it will focus on the quality of its information in the coming years. The different activities within the bus stop management provide different, complex information flows. The complexity has to do with the province that distributes the tasks through several departments and works together with several external partners in the chain.Research, commissioned by the province of Groningen. The province of Groningen asked the question how the quality her bus stop data could be improved.

A lab-based test setup was developed to simulate a novel droop rate controlled DC bus charging plaza installation in the Netherlands. The system consists of multiple bidirectional DC charging points, a PV array and a bidirectional grid connection. Currently the installed system employs linear droop control at the charge points and active grid connection. This lab setup allows for the testing of new control schemes, such as piecewise linear droop control, before implementing in the installed system. The simulations performed in this study investigate a variety of power flow scenarios and determine appropriate voltage and current setpoints and control mechanisms.

Many cities in Europe have ambitious goals when it comes to making their public transport buses emission free. This article outlines the reasoning behind the choices made in the city of Amsterdam with regards to charging infrastructure for electric buses. Emphasising the importance of operational demands, and taking into consideration relevant context factor for this city in particular, the article provides pointers for cities, public transport operators (PTOs) and original equipment manufacturers (OEMs) that are considering to introduce emission free public transport by bus.

In Germany, public transport organizations are mainly owned by public authorities. Procurement in Hamburg involves the buses and infrastructure instead of transport services. The procurement process for buses and infrastructure is performed by the transport companies. Such processes must meet German and European public regulations. Therefore, public tender and procurement procedures for buying buses by German Public Transport Operators (PTOs) can be more complex and lengthier than procurement by private PTOs in other countries. As a result, the public transport companies are not primarily driven by profitability, but also by obligations towards the public and political aims. Obligations can comprise to provide affordable, environmentallyfriendly transport services for the citizens. In Hamburg, the public authority incorporates obligations (requirements) for the e-buses in their tendering documents. In Utrecht, as well as most of the rest of the Netherlands, public transport is carried out by private companies, under an operating contract (concession) with a public transport authority. In Utrecht, this authority is the province of Utrecht. The e-buses are the operators’ private property and they are obliged to account to the province of Utrecht for their implementation of public transport. When the province of Utrecht procures the operation of public transport services by means of a European tendering process, private transport companies can offer a bid for this tender. Both, the authority and operators, want to provide good public transport for their customers, but they both have different goals. The operators want to earn a reasonable profit margin on public transport, while the authority wants to fulfil certain public policy goals. The tendering process is where these two come together. It is a strong mechanism to get the best ‘value for money’ out of the market – for example, the most public transport, or the highest number of e-buses running in the area, within the available budget of the public transport authority.

This study presents a model-based analysis of the groundconnectivity performance of the future Santa Lucia-Mexico City multi-airport system. The plan of the currentgovernment is to connect the two airports by a dedicatedline, either by bus or other transport so that passengersand airlines can get the benefit of a coordinatedoperation. Performance indicators such as minimumconnecting time, vehicle utilization and passengerwaiting time are used to evaluate the future performance.Results reveal that when all passengers are allowed to usethe connection, a big number of vehicles are required forproviding a good level of service while in the case of arestricted use to only transfer passengers the operationwith Bus would have a good performance.
