CO2 Barometer

In this PhD project by Marko Kapetanović, an integrated model for dynamic monitoring and prediction of CO2 emissions of regional railway services is developed, following a life-cycle approach. The project is performed in close cooperation with Arriva, the largest regional railway undertaking in the Netherlands. Possibilities and measures to improve the energy efficiency of railway operation and to reduce the total emissions on the network are identified and assessed, including alternative propulsion systems such as hybrid, plug-in hybrid, fuel cell-electric and battery electric, together with a range of energy carriers. Analyzed fuels and energy carriers include LNG, first and second generation biofuels, hydrogen and electricity, with examined various alternative production pathways. Check the main output of this project below.

The wider benefits of high quality public transport for cities

The true value of public transport is often underestimated systematically while assessing transit impacts of proposed projects. During the planning and assessment of new or improved connections, infrastructure or services, often only the costs of operations, construction and the revenues with regard to fares and travel time savings are accounted for. This approach provides insights into the performance of public transport to some extent, but disregards many other (positive) effects the provision of public services has. Many of which impose an advantage over competing modes of transport. This could result in the postponement or even cancellation of plans, as means are scarce and invested where gains are directly visible. Thus, to enable a fairer assessment of public transport plans, more insight is required into the wider benefits of its operations and impacts on passengers and the environment.

To gain these insights, we developed a methodology to quantify the value of public transport using the five E’s: Effective mobility, Efficient city, Economy, Environment and Equity. Together these aspects provide a better indication of all potential benefits of public transport.
