Certainly in terms of providing an integrated system, the UK fares substantially better than a number of countries I am familar with:
France:
In Paris, the ticketing arrangements are different depending upon the mode of transport or destination. If you're on the Metro, Bus or Tram, generally a single t+ ticket will suffice for a single journey, including connections. If you're on the RER, it matters which zone you are in, as only Zone 1 RER stations accept ticket t+. If you're going to an airport, you need to pay a special fare in many cases, OrlyBus, RoissyBus, OrlyVAL and the RER at CdG are only accessible with an Airport Access fare (or appropriate Paris Visite pass).
In most of the rest of metropolitan France, the TER local train system tends not to be integrated with the local transport ticketing:
Lyon - TER Trains + TCL Metro/Tram/Bus - only if you want a monthly smartcard.
Marseille - You can buy an integrated TER/RTM pass, but only if you want one that is valid throughout Bouches du Rhône (incl. Aix-en-Provence and Arles). Oh and you need to pay extra if you want Airport shuttles included. The benefit is the integrated pass also includes most of the other cities' bus systems, and the departmental coach network.
Lille - Local TER ticketing is integrated into the TRANSPOLE network, and visitor passes are available that include TRANSPOLE and wider TER travel (but not on the bus systems of the other cities you can travel to).
Toulouse - only one TER line in the conurbation is available on a TISSEO ticket or Pass, and then only for its suburban section (a change onto the Metro is required to reach the city centre using a TISSEO ticket). I believe a regional smartcard is available that can have multiple products loaded, but you have to be a French resident to get it.
Bordeaux - The only combined TER-TBC tickets are those combining a TER season with a TBC pass in one ticket. Normal TBC tickets do not include TER, and it does not seem to be possible to get a pass that includes TER, TBC and Gironde Cars (the regional coach services)
In most French cities, the city bus or tram network tarifs do not include the regional or departmental coach and bus networks. This includes many small cities, where a substantial portion of the local bus transport system can be provided by the departmental (inter-city) bus routes, much as in the UK.
Spain:
In Valencia, Spain, only commuter tickets can include Regional (MetroBus). Tourist tickets only incorporate Metro/Tram/City Bus (EMT). No integrated ticketing with RENFE Cercanias exists, and the Metro stations do not share concourses with the RENFE stations.
USA:
The USA tends to make it difficult to integrate modes as well:
New York
NYC Bus & Subway share a tarification system, using MetroCards for PAYG or weekly/longer travelcards.
LIRR, Metro North and LI Bus, despite also being New York MTA systems have very little integration in terms of ticketing -- the best you can get is that your LIRR or MNR ticket can also be bought with an attached PAYG MetroCard for use on the Subway/Bus. Remember, also, that weekly travelcards are not acceptable on the Express bus system unless you have an additional top-up pass. Bizarrely, this often makes it more expensive to use express buses than the subway.
Additional fares are payable for the JFK AirTrain (which only goes as far as Howard Beach or Jamaica in Queens), no integrated through tickets are available, despite it already being a difficult trip given the changes required to reach Manhattan. AirTrain will use stored value on your PAYG MetroCard as payment. What's not clear is if you can combine PAYG balance with a pass - my gut instinct is no.
PATH subway, NJ Transit (including NJ Rail, Newark and Hudson light-rail) and Amtrak all have their own tarification systems as well, the only sop to integration is that MetroCard PAYG value can be used to pay a PATH fare.
So, a week-long holiday by public transport in the NY region could end up with a plethora of different tickets and passes, many of which will look similar (How different will your PAYG MetroCard - for AirTrain and PATH - look from your weekly MetroCard pass?)
New York also has the issue that the majority of the regional train service stations were built to compete with the subway (or v.v.) and therefore do not form integrated complexes. AFAICT, only LIRR Atlantic Terminal, Penn Station and Grand Central actually incorporate subway station entrances into their complexes. All of the other interchanges require a transfer via city streets (although in the case of Jamaica LIRR, the entrance is right outside).
Chicago has a similar problem, with CTA, PACE and METRA all operating indepdent ticketing systems, and a lack of station integration. None of the METRA and CTA 'L' stations share a common concourse or entrance, and there's the ridiculous fact that the main downtown terminals for rail traffic in Chicago (Union Station, Millennium Station, Oglivie Station) are not even adjacent to 'L' stations - Union Station, one of the most important Amtrak and METRA terminals, is three blocks from an 'L' station.
The only combined system ticket is valid on CTA (downtown) buses only during typical commuter hours.
Many of the other systems share similar idiosyncracies
- LA has poor station integration and no fare integration between Metrolink and LA Metro.
- While the bay area of CA (San Fransico etc.) has an integrated card called Clipper, you still have to load separate products on to it for each transit system you want to use - Caltrain/BART/Muni/VTA/SamTrans/ACTransit - and it's not valid on Amtrak or ACE trains.
- Washington DC's WMATA is not integrated with VRE or MARC trains.
However some systems are surprisingly well integrated:
- Philadelphia (SEPTA) has a variety of fully integrated tickets (including with NJ Transit, but unfortunately not PATCO across the river), but many multi-mode transfers (subway-regional rail etc.) require street-level transfer.
- Boston (MBTA) has a reasonably integrated system
- Seattle and Tacoma use an Oyster-like card called ORCA, and although there are no weekly or daily passes, the system will automatically calculate any appropriate transfer discounts when changing vehicles or modes.
-
So certainly in the USA and France, very few cities offer the benefits that most UK municipal visitors can realise through buy-once-go-anywhere tickets.
In my travels so far, I have seen nothing like the London TravelCard or PlusBus fares where you can buy unlimited local transportation in a city the other side of the country along with your intercity travel.
We also integrate our metro networks with our local and intercity rail networks at least as well as the 'good' countries in Europe, with metro/tram stations typically forming part of the main station complexes (true in London, Birmingham, Manchester, Newcastle, Sheffield, Nottingham, Liverpool, Sunderland and Glasgow to some extent). We also are quite good at building dedicated bus interchanges immediately adjacent to, or as part of rail stations.
Our integrated ticketing products in the main cities almost always have an option to have heavy rail services form part of the mix (certainly true for London, all PTE covered cities, Bristol and Nottingham), and they tend to cover all buses in the appropriate area.
Finally, we have a wide variety of area explorer and rover tickets which can cover all services in an entire region, albeit these aren't always multi-mode.
They aren't as simple to use as the German fully integrated systems, but I submit that we have traded complexity for convenience, in that there's often a ticket ideal for many different sorts of tourists, and the integration between systems (at least in the larger cities, or where PlusBus is appropriate) is far more seamless than many places can offer, both in terms of ticketing and making connections.
