Transport is indispensible to society and the economy. It also causes traffic jams, accidents, air pollution and the emission of greenhouse gases. How can we ensure the efficient, safe and reliable transport of people and goods? And how can we be kind to the environment whilst doing so?
Our research focuses on the development of knowledge concerning efficient, reliable, safe and clean transport. The TU Delft researchers working on this theme belong to the global Top 5 in the transport field.

Measuring, modelling, optimising

Characteristic of our research is the attention paid to measuring, modelling and optimising transport. We carry out research into the transport of people and goods by road, but also, for example, by rail or over water; we examine traffic flows, the provision of information to travellers and road users, the planning of ports and waterways, and the improvement of public transport. Information and communication technology is increasingly being used for efficient, reliable, safe and clean transport.

Transport facilities and their efficient utilisation

We carry out research in three related research fields:

  1. The design and planning of infrastructure and infrastructural networks
    We carry out research into the design of reliable, sustainable multimodal transport networks for the Randstad conurbation in the Netherlands whereby attention is primarily paid to the linking of various forms of public transport. How can the range of multimodal transport be attuned to spatial developments such as housing and industrial estates? What is the relationship between reliability and speed in a heavily-used public transport system? This knowledge is used to design new multimodal transport networks for new housing estates and urban areas.
  2. Interaction between the demand for transport and the provision of facilities
    We carry out research into the effect of travel times and the reliability of modes of transport (bicycles, cars and public transport) on travellers’ transport choices. What effect does building or widening a connection or providing public transport have on traveller behaviour? This knowledge is used to improve and assess the efficacy of measures aimed at improving transport. 
  3. Efficient use of transport facilities
    We, for example, measure how many cars traverse a particular section of motorway within a specific amount of time and examine which traffic density leads to the development of traffic jams: what happens if you provide more traffic information to motorists? What effect do variable speed limits have on the development of traffic jams? This knowledge leads to new ways of improving traffic flow progress, for example, by homogenising traffic flows and improving the utilisation of alternative routes within the road network as a whole.

The CEG faculty collaborates with other TU Delft faculties in the field of transport as well as with other universities in the Netherlands and abroad, but also with Rijkswaterstaat [the Directorate General of Public Works and Water Management], TNO, engineering firms and the industry. Together we devise solutions based on the latest scientific insights which are applicable in practice. All knowledge is immediately translated into education which therefore always consists of the latest scientific insights.

Cooperative vehicle and road systems
In collaboration with Shell, TU Delft studies how road transport can be optimised as far as fuel consumption and the emission of pollutants is concerned. The researchers thereby emphatically examine cooperative vehicle-road systems. Cars hereby not only communicate amongst themselves, but also with roadside stations. In order to optimise traffic progress, Shell and TU Delft are, for example, examining the computerisation of driving tasks and speed and lane recommendations using communication between vehicles and with the roadside stations.  

Insurance premium dependent on driving behaviour
TU Delft is studying whether driver behaviour could be used in a system of variable premiums for car insurance. To this end, the university is cooperating with TNO, NXP, TomTom and Logica. The idea entails drivers paying less if they adhere to speed limits, drive outside the rush hour a lot and primarily take ‘safe’ roads. All these factors are relatively easy to ascertain using modern ICT.
