This post is written in the context of the decision to move from the current honor system to the barrier controlled access rail transit system in Vancouver. The capital cost involved by the move is estimated at $100 millions [3]. the cost of fare evasion on the Vancouver rail system is estimated at $3.5 millions per year [4].

Fare evasion

At the beginning the Paris subway had human fare control at its gates. In a move to save on fare control operating cost, the Parisian transit agency, had started to implement turnstile, pretty much in the style seen on the Toronto TTC or the Vancouver seabus…
But Quickly, it appeared that the lack of human control once in the subway system was a pretty good incentive to dodge the turnstiles.

The full display of fare evasion as well as turnstile dodging technique associated with perceived impunity of such behavior, has encouraged wide spreading of similar conducts in the Paris subway, then adopted by people of all conditions as illustrated below

That has lead the French transit agency, the ratp to adopt more elaborate faregate, now featuring full door.

  • either the door stay open long enough, and several people (following close enough) can pass the gate with a single fare.
  • or the door close very quickly, and you can’t cross the gate with any luggage, or stroller.

In despite of tremendous investment in fare gating, fare evasion is estimated at 10% in the Parisian subway what is in fact comparable to the access free subway in Berlin [7] and way much more than the 5% measured in Vancouver [4] or 6% on the access free subway of Los Angeles in 2007 [8]

in any case, the turnstiles are an impediment slowing down the flow of transit riders, and the good thing introduced by smart-cards, is that it allow to mitigate this point.

One will note that if fare evasion was the justification for a fare gating, subsidy could be then not necessary. In reality fare evasion on Vancouver transit system is as low as 2.5% system wide (5% on the Skytrain, what amount to $3.5 millions revenue lost a year, which could be only partially recovered by turnstiles) [4], that is nowhere near to able to justify an $100 million investment [3]. In comparison of other systems [7][9][10], there is a generally good level of compliance in Vancouver, observation that the casual observer could have confirmed during the Olympic games, by watching the sometime hour long line-up at the fare vending machine .


It has been a strange and unsubstantiated claim done by the British Columbia government that the fare gates could increase the security on the skytrain [2].
The opposite could be more true: In fact, the diversion of resource going to the maintenance and amortization of the fare gates, instead of human staffing are of nature to make the system less safe.
The creativity of the fare gate dodgers and other smugglers being boundless, it appears that nothing is able to replace human staffing as the picture below illustrates and could also apply to Canada [6]


Police, at Paris Gare du Nord, in April 2007, makes sure everyone is paying his fare!

Nevertheless, the unsubstantiated BC government claim will suffice to justify to allocate $70 millions of subsidy by senior government toward a fare gating system on the Vancouver rail network [3]

The smart card

Another strange association has been done in BC between the turnstile and the smart card. Both can be put in place separably, as it is done on numerous transit network.

smartcard access to the subway of Rennes, France, is done without turnstile. Nevertheless, notice how the smart card readers are placed in prominent position on the farepaid zone line (credit photo wikipedia commons)

The distance based pricing

That seems the only reason a network transit the size of the Vancouver one, could wish to adopt turnstiles control. Controlling entry and exit of the network effectively allows the transit operator to charge by the distance, as done in some rail network, more noticeably on the Hong Kong MTR [5]

Still, in this case, one will find curious the government interference in a matter which should be a priori leads by economic consideration.

Even so: the logic would like that the smart card come first, since it can work currently in the 3 zones model, which is common to numerous network, like the Paris one, and turnstiles in a second phase. Curiously, according to the VancouverSun [1], it is the reverse we gonna see, and suffer all the inconvenience of the faregate, including compromised ease of access to the transit system for people with special needs; from the traveler with luggage, to the wheelchairs, without the advantage of the smartcard.

[9] Toronto TTC has a fare evasion of as low as 0.7% on its subway [7], but one should note that all the turnstiles lines are constantly monitored by human staff, via strategic location of ticket office at the stations, as well as additional staffing at rush hours. Non staffed entrance, are equipped of full rotating door, unable to accommodate people with special need (wheelchair, stroller,…). In conclusion, it could be hard to conclude that the low fare evasion number is achieved by turnstiles alone. This observation can be confirmed by the number from the New York subway able to reduce from 3.5% to 0.5% the level of fare evasion through policy measures [7].
