How smart are alternative routes?

Posted by Dr. Ir. Steven De Schrijver on 13/06/2016


The kilometre-based charging system in Belgium has been the topic of lively debate over the past few months. Before the introduction of the new tax on April 1, various figures were bandied around in terms of what the exact impact on transport costs would be. Some mentioned an average of 8%, others believed that the extra costs would vary between 2% and 12%. But the only way to calculate the true impact of the kilometre-based charging system is by simulating it on your actual transport lanes. In addition to the transparency these simulations offer you, you will also be much better prepared to discuss price increases with your subcontractors and your customers alike.

Multimodal transport at lower costs. Are you ready?

Posted by Dr. Ir. Steven De Schrijver on 31/05/2016


Do you know the difference between multimodal, intermodal, co-modal and synchromodal transport? What they have in common is that they all combine different modes of transport and offer a sustainable alternative to road transport. But there are differences between them too. Multimodal freight transport describes a transport chain which integrates various different modes of transport. The largest part of the journey is completed by rail, air, sea or inland waterway, with only the first and last stages of transport being by road. In the case of multimodal transport the cargo is re-packed or re-loaded whenever it is transferred to a different mode of transport. Intermodal transport differs in this respect, since the cargo then only changes mode of transport and not ‘packaging’ too – it remains in the same container, swap body or trailer.
