Pavement Temperature Data Maps: Asia
Navigating the Map: Zoom in on the
map to display the location icons (red circles). Green, yellow and reddish circles
(with numbers) are location clusters and indicate the number of points in the
vicinity for which data is available. Either click on the location clusters or zoom
in further to decluster. Pavement temperature data is displayed as attribute
information for each station. Click on the location icon (red circle) to display the
pavement temperature and other attribute information for each station. Alternatively,
search field can be used to locate the station of interest. Units: All temperature
data in degrees Celcius, Station Elevation in metres.
Data Source and Period
Data Source:Daily air temperature data sourced from National Climate Data
Centre, US (NNDC) - Climate Data Online (CDO) website
https://www7.ncdc.noaa.gov/CDO/cdo.
Data Period: Maximum period of 30 years (1989-2018).
Note: Temperature data for the entire 30 year period
was not available for certain stations. Data periods for which analysis were
done are indicated in the map below under attribute info for each station as
'Data Start Date: ....' and 'Data End Date: ....'.
Data Analysis
Daily air temperature data sourced from NNNDC-CDO website analysed using
Python PANDAS library to arive at the Mean, Maximum and Minimum air temperature
records for each station.
Air Temperature to Pavement Temperature conversion based on LTPP, SHRP and
Shell WMAPT models.
Pavement temperature data exported to GIS platform (QGIS) for further
analysis.
Preparation of web maps using qgis2web plugin in Leaflet.js, javascript
library.
Results and Outputs
Weighted Mean Annual Pavement Temperatures (WMAPT) for each station based on
the Shell WMAPT (AustRoads) Model
Low and High Pavement Temperatures for stations based on Long Term Pavement
Performance (LTPP) High and Low
Pavement Temperature Model with 50 and 98% reliability (US Federal Highway
Administration Report: FHWA-RD-97-103).
Low and High Pavement Temperatures for stations based on Strategic Highway
Research Programme (SHRP) High and Low
Pavement Temperature Model (US Federal Highway Administration Report:
FHWA-RD-97-103).
Additional Information: Station Details, Data Period, Minimum and Maximum Air
Temperatures and the 7 day moving average Maximum Air Temperature recorded during the
data period, Dates of recorded Minimum and Maximum
Air Temperatures etc.
For LTPP and SHRP Models, the high pavement temperature was derived from the
highest 7 day average air temperature per year during the data period and the Low
pavement temperature from the lowest air temperature per year during the data period.
The altitude, air temperature and
latitude data ranges used in the
development of LTPP low temperature model are limited to the values given below.
- Latitude: 27° and 52°.
- Elevation: 11 m to 1586 m
- Air Temperatures: 4.6 to -41.5 ℃
- Pavement Temperatures: -33 to 13.7℃
The altitude, air temperature and latitude data ranges
used in the
development of LTPP high temperature model are limited to the values given below.
- Latitude: 27° and 52°.
- Elevation: 11 m to 1586 m
- Air Temperatures: 21 to 47℃
- Pavement Temperatures: 31.4 to 58.3℃
It
may be noted that the majority of stations that fall within the Asia region are
located beyond the range and the low and high pavement temperature values for
the
stations
shall be used with caution.
