BRT in the Netherlands

We here at third rail harbor rather mixed feelings about BRT. Those feelings aside, I’d like to point readers to an article in Mass Transit Magazine which discusses the Netherlands ' and innovative Phileas Advanced Public Transport (APT) system. Named for Phileas Fogg in Verne’s “Around the World in 80 Days,” the BRT system is billed as an economical alternative to light rail for cities like Eindhoven whose relatively small population translates to modest ridership. Features of the system and it’s vehicles include:

  • An electric-hybrid propulsion system with an engine that uses liquid petroleum gas to drive an electric generator.
  • All of the vehicles' wheels except the front two are driven by individual electric motors.
  • Regenerative braking is used to recover deceleration energy, and excess electrical energy is stored in Ni-MeH, so the Phileas can operate up to 3 kilometers on electric power in the city center
  • Controllable wheels on the vehicle allow it to move sideways towards the stop.
  • An electronic lane assistance and precision docking system can bring the vehicle to a stop within a centimeter of its docking position. The vehicle automatically follows a predetermined route guided by magnetic plugs embedded in the road surface at 4-meter intervals.

    The above features, combined with an electronic guidance and control system which ensures that vehicle locations are always precicely known, seem to me to offer a viable alternative for smaller cities, which might not be able to meet the infrastructure costs of light rail or tram systems.

    I must say, that sounds really neat.

    I think it's a beautiful vehicle and would be an excellent prospect to curb our current light-rail mania in this country.

    Craig: why do you consider it better than light rail? Or more generally, what do you consider to be the problems of light rail and in what ways is this BRT better and worse than light rail?

    A thought--I wonder about using NiMH batteries. My understanding is that lead-acid batteries are usually preferred over NiMH except when the weight of lead-acid is a significant problem, since NiMH is much more expensive. I would think that for a multi-segment bus, battery weight would be a much smaller fraction of total weight than in a 4 passenger automobile.

    Hi--I'm studying transportation at MIT and considering writing my thesis on people's perceptions of BRT. I stumbled accross this blog and was wondering if anyone could tell me about it (who posts, is it related to some organization, etc) thanks,
    miriam
