Heated cycle lanes to warm Dutch winter cyclists
Infrastructure in Holland is pretty well adapted to cyclists; there is always room for improvement though. I thought we had a great improvement recently with the green lights for cyclists when it rains (see here) but this one is surely a winner:
Towns in the Netherlands are considering a proposal to heat cycle lanes to encourage greater use of bicycles in winter. In the near future a trial will start in the city Zutphen and the province Utrecht.
The scheme will use geo-thermal energy to prevent ice forming. This means the asphalt will be cool in the summer and warm in the winter.
The prognosis is that these bike paths will hardly cost more than normal bike paths and very little energy is needed to keep the paths warm in the winter. The reduction in crashes due to iced over roads will most likely outweigh the additional costs of creating the paths.
I guess this is why you can be car-free in Holland without getting stares.

Wouldn't this create issues with fog and condensation on the paving surface making it slippery?

Fog and condensation occur when you take warmer, humid air and cool it or have it come in contact with a cold surface. This would be the opposite - the cold and dry ambient air contacting a warmer surface of the heated pavement. Sounds reasonable for areas that have enough cycle traffic to justify the energy expenditure.

While the geothermal is obviously fairly low energy use; what mechanisms are being used to deliver that energy to the road surfaces and what is the source of the energy for that delivery?

And if the route already has enough traffic to justify the energy expenditure it would not likely have much ice accumulation, since the traffic would tend to melt/disappate the ice.
