+==== Field Exclusion ====
+Journeys API allows exclusion of returned fields depending on the end point. Below are list of end points which allow field exclusion.
+<pre>
+api/1/journey-patterns
+        - exclusions: stopPoints, journeys
+api/1/journeys
+        - exclusions: calls
+api/1/routes
+        - exclusions: journeyPatterns, journeys, geographicCoordinateProjection
+</pre>
+For each end point a single or multiple exclusion can be used. Multiple exclusions are separated by comma. For example a client might call:
+* http://data.itsfactory.fi/journeys/api/1/routes?exclude-fields=journeys
+* http://data.itsfactory.fi/journeys/api/1/routes?exclude-fields=journeys,journeyPatterns
+* http://data.itsfactory.fi/journeys/api/1/routes?exclude-fields=journeys,journeyPatterns,geographicCoordinateProjection
+Also the vehicle-activity end point support field exclusion, please see that section for details on field exclusion on vehicle-activity end point

+==Stop Monitoring==
+Journeys API allows clients to access real-time location of vehicles moving through the street network from stop point perspective. To do this, client would make a HTTP GET request to url
+<br><br>
+http://data.itsfactory.fi/journeys/api/1/stop-monitoring?stops=0001,0002
+<br><br>
+where stops argument contains a list of stop short names for which to fetch the data. NOTE: you can specify at maximum 100 stop short names into single request
+The call would result in a following response:
+<pre>
+{
+: [
+    {
+      lineRef: "3R",
+      directionRef: "2",
+      vehicleLocation: {
+        longitude: "23.7337863",
+        latitude: "61.5007787"
+      },
+      operatorRef: "TKL",
+      bearing: "70",
+      delay: "-P0Y0M0DT0H1M18.000S",
+      vehicleRef: "TKL_41",
+      journeyPatternRef: "3R",
+      originShortName: "1028",
+      destinationShortName: "0002",
+      originAimedDepartureTime: "2016-04-23T02:35:00+03:00",
+      call: {
+        vehicleAtStop: false,
+        expectedArrivalTime: "2016-04-23T02:53:00+03:00",
+        expectedDepartureTime: "2016-04-23T02:53:00+03:00",
+        aimedArrivalTime: "2016-04-23T02:55:00+03:00",
+        aimedDepartureTime: "2016-04-23T02:55:00+03:00",
+        departureStatus: "onTime",
+        arrivalStatus: "onTime",
+        visitNumber: "24",
+        vehicleLocationAtStop: {
+          longitude: "23.7337863",
+          latitude: "61.5007787"
+        }
+      }
+    }
+  ]
+}
+  ...
+</pre>
+The response contains a list of elements (grouped by requested stop short names) described above. Following fields are present:
+* lineRef specifies the line where the bus is currently operating.
+* directionRef sepecifies the direction the bus is travelling on the line. 1 = from origin stop to destination stop, 2= from destination stop back to origin stop.
+* originAimedDepartureTime specifies which time the vehicle departed from the origin stop
+* latitude and longitude specifies the map position of the vehicle at the time of the observation
+* originShortName specifies the number of the stop where the vehicle started
+* destinationShortName specifies the number of the stop where the bus is heading to
+* bearing specifies the direction the vehicle is travelling
+* delay specifies the relative time the vehicle is behind or ahead of its planned schedule
+* vehicleRef uniquely identifies the monitored vehicle
+* call element tells when the journey is expected to reach the requested stop, as well as its departure estimation
+The response data changes once in a minute, so clients are not recommended to poll the interface very often.
+==GTFS Zip files==
+Journeys API provides public transport data in form of GTFS ZIP files. These files are meant for purposes where offline usage of public transport data is required. Please see https://developers.google.com/transit/gtfs/reference for more details on GTFS.
+Zip files are available at: http://data.itsfactory.fi/journeys/files/gtfs/
+Journeys API provides two zip files:
+* gtfs_tampere.zip is a file which adheres strictly to GTFS format. This file however does not include all information available via Journeys API GTFS Zip files. Use this file when you need to be fully compatible with GTFS
+* extended_gtfs_tampere.zip is a file which extends standard GTFS Zip file with information about tariff zones and municipalities. Use this file when you need the extra info and when you do not need to be fully compatible with GTFS. Please note however, that extended GTFS Zip file is not in conflict with GTFS specification, but extends it. So in most cases you should be able to use it.
