Contactless on the tube and rail
In message , at 12:55:07 on
Wed, 17 Sep 2014, Paul Corfield remarked: Based on anecdotal feedback it seems the card / reader txn time for CPCs is marginally longer and if there is significant transfer to CPCs that could slow down gate throughput. If the subsequent conversion of Oyster is also slower than current Oyster then that's not going to be wonderful. Southern and the DfT have been launching the "Travelcard on ITSO" functionality for the Southern "The Key" today. I saw something on Twitter but no press releases were around earlier. I hadn't noticed that, thanks. Apparently it went operational (some would call that a 'soft-launch') about three weeks ago. Apparently ITSO card read times are not quick either Even slower than CPC I'm pretty sure. Not that this matters on much of National Rail with really slow 'clockwork' barriers. so we face the prospect of gate throughputs falling. Indeed, although if they started to mark some gates as "Oyster only" (even if it's a bluff) that might keep the throughput up for people in the know. This is in the face of rising patronage and slow gate throughput means you need more gates for a given throughput which could have serious implications, if TfL change their standards, for reconstructing stations. Another option would be to redefine the ITSO use paradigm, and make it more like CPC with a "read only" and hence shorter transaction time at selected gates with selected products (such as TfL/Travelcards), with the results being reconciled overnight (like CPC) with some sort of centralised auto-topup purse. There are a lot of "ifs" there but I hope someone is paying attention to the effect of changing the blend of card technologies and read times. On the other hand it may just be another instance of Hutber's Law, with a so-called improvement actually giving worse/slower service to the end user. Who would have predicted when they decided to phase out slam-door trains that one of the results would that instead of being able to exit the train from about minus-two seconds before it stops, you always have to wait until about fifteen seconds afterwards. Manual ticket buying has only got difficult since the industry changed from issuing Edmondsons for cash (about 5 seconds all-up) to the current offering which have to be picked from a crt, take ages to print, and even longer to pay for by credit card. -- Roland Perry |
