1. MAKING API CALLS
API calls need to be made programmatically in regular intervals to obtain the constant stream
of data for your respective development or research needs. For illustration purposes, the API
call below is being made via a third-party application – Postman.
Steps to making an API call:
1. Download and install the Postman from https://www.getpostman.com/. Fire it up!
2. Make sure Http method is set to GET.
3. Enter the URL (refer to subsequent pages in this document) in the field request URL.
4. Enter your AccountKey under Headers.
5. (OPTIONAL STEP) The “accept” header allows you to specify the response format of
your API call. Default is JSON. Specify “application/atom+xml” for XML.
6. Click on the Send button.

Figure 2-2 on the next page shows the JSON response of an API call made for the Traffic
Incidents dataset.

LTA DataMall | API User Guide & Documentation
Version 4.0 (28 Jul 2017)
Figure 2-2: API (JSON) Response as shown on Postman.
With the exception of the following 3 APIs listed below (see Table 1), API responses returned
are limited to 50 records of the dataset per call. To retrieve subsequent records of the dataset,
you need to append the $skip operator to the API call (URL).
For example, to retrieve the next 50 records (51st to the 100th), the API call should be:
http://datamall2.mytransport.sg/ltaodataservice/TrafficIncidents?$skip=50
To retrieve the following set of 50 records, append ‘?$skip=100’, and so on. Just remember,
each URL call returns only a max of 50 records!

LTA DataMall | API User Guide & Documentation
Version 4.0 (28 Jul 2017)
Here’s an example of how you can retrieve the data programmatically. This example is coded
in Python 2.7. As mentioned previously, this API call only returns the first 50 records.
import json
import urllib
from urlparse import urlparse
import httplib2 as http #External library
if __name__=="__main__":
#Authentication parameters
headers = { 'AccountKey' : '6HsAmP1e0R/EkEYWOcjKg==',
'accept' : 'application/json'} #this is by default
#API parameters
uri = 'http://datamall2.mytransport.sg/' #Resource URL
path = '/ltaodataservice/TrafficIncidents?'
#Build query string & specify type of API call
target = urlparse(uri + path)
print target.geturl()
method = 'GET'
body = ''
#Get handle to http
h = http.Http()
#Obtain results
response, content = h.request(
target.geturl(),
method,
body,
headers)
#Parse JSON to print
jsonObj = json.loads(content)
print json.dumps(jsonObj, sort_keys=True, indent=4)
#Save result to file
with open("traffic_incidents.json","w") as outfile:
#Saving jsonObj["d"]
json.dump(jsonObj, outfile, sort_keys=True, indent=4,
ensure_ascii=False)

ADVISEMENT ON FRONT-END IMPLEMENTATION (BUS APPS)
1. [EstimatedArrival] Display of Advisement Messages when there is NO Bus Arrival Data
In the event where data is not available (be it in partial or in full) on the API, you may want to display
some form of ‘status texts’ to advise your app users on what’s going on, as far as bus service
availability is concerned. To do this, you will need to take reference from two data points – (1) the
presence or absence of Arrival data itself, and (2) the bus service operating hours at each bus
stop which you need to obtain via the Bus Routes API.
With those two data points gathered, you will arrive at the following possible scenarios:
#
Operation Status
Data Availability
Advisement Message
a.
Bus is in operation
Arrival data is available
(none required)
b.
Bus is in operation
Arrival data is NOT available
“No Est. Available”
c.
Bus is NOT in operation
Arrival data is NOT available
“Not In Operation”
d.
Bus is NOT in operation
Arrival data is available
(none required)
For scenarios (b) and (c), you may display advisement messages like those suggested in the table
above, or any other user-friendly and appropriate variants at your discretion.
Next, you should note that Arrival data may be available on the API even when bus services are
supposedly NOT in operation (as per scheduled operating hours) – reflected as scenario (d) in the
table above. This happens,
a.
before first bus(es) begin their service from Bus Interchanges / Depots in the mornings, and,
b. when last bus(es) at night are running behind schedule; slightly past operating hours.
Therefore, the general logic to be applied, is to always first display the Arrival data if it’s available
on the API, irrespective of the scheduled operating hours. Advisement messages like “No Est.
Available” and “Not In Operation” are applicable ONLY when there is no Arrival data on the API.

[Load] Colour Scheme Adoption
You may adopt this colour scheme to serve as visual indicators for the various loading values:
-
[Green] Seats Available
-
[Amber] Standing Available
-
[Red] Limited Standing
You are given the flexibility for the manner in which you display the colours, i.e. colour bars, coloured
timings, and accompanied with legends where appropriate and/or necessary.
4. [Feature] Wheelchair Accessible Buses
You are given the flexibility to display any symbols or labels
to denote oncoming buses that
are wheelchair accessible.
ADDITIONAL NOTE ON LOOP SERVICES THAT RUNS BOTH DIRECTIONS
Please note that some Loop Services are appended with ‘G’ or ‘W’ to denote their direction of travel.
You should account for and display these services individually – 225G, 225W, 243G, 243W, 410G, 410W.
