Many acknowledge that transportation in Hong Kong is structured efficiently. We see bus feeders located near Star Ferry terminals and bus stations located near some MTR stations. But one big challenge for newcomers in Hong Kong is how to get from one point to another, especially if the two are far from each other and no direct transport means connect them. It's fine for us long time residents. For example, it takes four methods to get to Central from my place (bus 2, bus M722, tram, and MTR). We who seem to know to go about the city. Or so I thought. How about longer routes?
Say for example I am from Ap Lei Chau and I want to go to Sai Kung. Or maybe Tung Chung to Chai Wan. Clearwater Bay to Wan Chai. And so on.
Now comes the Public Transport Enquiry System (PTES), initiated by the Transport Department, which allows the public to take the shortest route from point A to point B and how long is the travel time. PTES consolidates data from all public transport, including
buses and
minibuses,
the MTR,
ferries,
trams and
taxis. Wow, that's indeed amazing.
I used to marvel at
Citybus's similar feature, but PTES is indeed a great upgrade to that because it covers all other modes of transportation, along with estimated travel time. Maybe incorporating the data from traffic light system, travel frequency (some buses have more trips than others).
When it comes to estimated time, I hope PTES have factored in the following:
* Walking time on MTR stations. Causeway Bay MTR station has a long walk leading to the Times Square exit. Quarry Bay has multiple levels (platform leading to Po Lam is located deep underground). And so on.
* Waiting time for buses. Bus 2 runs more frequently than the shorter and more expensive M722. But the problem is more chronic for minibuses like in Jardine's Lookout area where passengers sometimes wait for more than 15 minutes!
* How many bus stops and pedestrian lanes will the bus pass by. Some pedestrian lanes have shorter breaks than others.
* Will the bus pass by major thoroughfares where traffic can get considerably bad.
* What season of the year or time of the day. It affects speed of travel and duration in bus stops (bus 529 to Braemar Hill's schools spends longer on bus stops as students board them during school season).
* Will passengers pass by major MTR interchanges and chances of missing out on next available MTR train due to overcrowding.
* Will it be possible to synchronize times among transport modes on interchanges? For example, arrival of ferries to Hung Hom is timed so it arrives just before a bus leaving for Kowloon City departs.
* If I live in a rural village not too far from Yuen Long or Ma On Shan, will my village be covered by this application? Or maybe I should just buy a car and install GPS?
I know I am digging deeper (and I have many other possible scenarios that help make PTES operate more accurately), which I think is good to know but unnecessary in coming up with a working prototype. But maybe for the sake of future improvements, if these weren't considered yet?
Public Transport Enquiry System transport search engine can be accessed at
http://ptes.td.gov.hk/ but it seems to lack even simple functionality. But I am sure upgrades will be available soon.
Thank you Transport Department for this application.
