我發電郵查詢GTFS-RT實時資訊所獲之回覆
[複製鏈接]
|
內容大致如下：
I am writing to enquire about the availability of estimated bus times for
buses in Hong Kong in GTFS-RT format. GTFS-RT is the de-facto standard for
public transport agencies to deliver real-time data, including vehicle
positions, trip updates (delays and cancellations).
I would like to produce a unified journey planner which allows passengers to
plan journeys according to their customised preferences, in an operator-
neutral way, on a real-time basis. In order to achieve this, I need the
timetable data and the real-time updates in an international standard (GTFS-RT
or SIRI-ET). However, I could not find any useful information about the
endpoints to access these information for your transport operator with a web
search.
Therefore, I would like guidance how I can obtain the timetable and real-time
data in GTFS / GTFS-RT formats, such that I can run a journey planner across
all transport modes and all transport operators and plan connections according
to the real-time data.
之後追問係：
Following up to your previous reply, are the estimated times available in SIRI-ET format, which is the European de-jure standard? Otherwise, what is the proper way for a third-party journey planner to load estimated times on a whole-network basis, such that we can plan the fastest connections across the whole territory, using the real-time estimated times?
For your reference, this is done by one of the two methods below, either by downloading a snapshot of the whole network at once, or for a larger transport network, by streaming estimated times as they become available for each trip.
I would appreciate a reply from the technical team on the enquiry above.

如果第一篇已經係九成內容嘅話，唔回你「關我咩事」都算畀面
顧客滿意度、提升品牌形象隻字不提真係犀飛利
至於relevant department恐怕都唔存在......
講到Nation Fail cancellation都睇到，19-33仲理你?

其實傾創科合作和傾技術是兩個不同專業範疇的事，樓主不如搵返合適的人去傾會好些，第二個email叫人搵technical team來答, 講真其實都幾唔尊重人。
Relevant department在某些公司是存在的, 如果我是這個department的人見到個咁既email，我都會比返個官方答案叫你自己去data.gov.hk算了。 |

還以為TDAS的出現會帶來轉機，不過看來都已經石沉大海了，系統建立了，錢花了，但就正如小巴的ETA一樣，data只是在雲端，地上的人得物無所用...（甚至是一無所知）

如果佢個application咁成功，我就用緊佢個隻而唔係bustimes或者realtimetrains吧

你咁樣係要人地俾data而唔係pitch人地合作喎
假假地連個deck都無你咁就想人地回應？

咁你而家用邊隻 application 可以整合晒所有交通模式嘅資料兼做 journey planning ？
Citymapper 嘅問題係你一長途，過咗某啲 arbitrary boundary 就即刻唔 work （佢唔係全國通用），例如我想由我屋企去 Solihull 某個 Bridge Club ， Citymapper 用唔到 （雖然呢點喺香港無關係，因為香港有 hard border ）。 Google 就出名垃圾大家都知。
bustimes 同 realtimetrains 唔係 journey planner ，佢唔能夠話你知你來緊星期日由屋企去80公里外某個山旮旯地方要搭咩車，我間中都有用來睇資訊（睇時間表同巴士嘅實時位置，主要係因為我隻 app 未整好呢個功能），但係唔多用； realtimetrains 加上因為 data licence 限制（佢唔用 National Rail 嘅 data - National Rail 嘅 licence 唔容許 mix with other predictions ，而 realtimetrains 有自己 predictions ），所以睇唔到即時 skip stop 同埋 last minute platform change due to set swap ，唔能夠用來依賴搭車，只能夠用來事後孔明（例如 Delay Repay ）。
同埋我隻 application 都未正式 release ，而家重係 beta 緊。

不如叫TD 喺GTFS度加返鐵路資訊先，簡單嘅做咗先雖然JT唔準但夠做multimodal search先

少甜啊唔該

唔牽涉到鐵路，單係搭巴士旺角去九龍城
你估九巴會唔會想見到啲客識上793，又或者城巴想唔想啲客上九巴堆流水?
定係可以narrow down到連公司都有比重?

假設你由London去Solihull，唔係turn up and go或者揸車去，正常人都識得拆開3程去plan：
- 起點至London火車站
- 火車
- Solihull火車站去目的地
(NB: 火車可以係其他交通工具，例如National Express)
Divide and conquer就已經可以解決嘅，又何必要搵晒全部options去計？
同埋係香港點樣會出現boundary issue？你唔係旨意連大灣區結果都一次過晒嘛？
如果你隻野係beta緊又得到公司批准，無理由唔會俾到deck人地巴士公司喎
好似美國呢間公司，佢地連合作都未有就已經有舊成品大家可以睇到
你仲停留係紙上問data access個階段，又點夠convincing？
