Each row array contains one or more element entries, which in turn contain the information about a single origin-destination pairing. See DistanceMatrixElement for more information. See DistanceMatrixElementStatus for more information. The total distance of this route, expressed in meters value and as text. The textual value uses the unit system specified with the unit parameter of the original request, or the origin's region.
See TextValueObject for more information. The length of time it takes to travel this route, expressed in seconds the value field and as text. The textual representation is localized according to the query's language parameter. The length of time it takes to travel this route, based on current and historical traffic conditions.
The duration is expressed in seconds the value field and as text. The duration in traffic is returned only if all of the following are true:.
If present, contains the total fare that is, the total ticket costs on this route. This property is only returned for transit requests and only for transit providers where fare information is available.

Using coordinates will always result in the point being snapped to the road nearest to those coordinates - which may not be an access point to the property, or even a road that will quickly or safely lead to the destination.
Google do not provide much documentation on the actual accuracy of their journey times, so it often comes down to the potential user to test this for themselves. Having used Google Maps for my own in car navigation for a few years, I believe the predicted journey times are indeed very accurate.
I would quite often let the person at the other end of my journey know my ETA and bingo arrive at that exact time. However, I had not validated the accuracy of the journey times. This is exactly what I have been doing over the last couple of months. Over the past two months, I have noted the predicted journey time at the start of any car trip and measured this against the actual time. Having completed the analysis, I can confirm that, as expected, the Google Maps journey times are very accurate.
Below is a summary of my findings. To undertake the analysis, I would enter my route into Google Maps, note down the predicted journey and arrival times and compare these to the actual times. I tried my best to stick to good driving behaviour, speed limit etc. I conducted 56 individual trips with an average distance of 18 miles and journey time of 32 minutes.
The trips were mainly from my house in Hampshire to locations in the South of England. I spent an average amount of each journey on motorways, A and B roads, with the odd country lane thrown in for good measure. Andy Meek. Maren Estrada. Combined with user activity and, at times, sensors from the department of transportation, Google can reasonably predict an estimated time of travel. By utilizing location services, Google can record and analyze repetitive user behavior and even detect new routes.
Location tracking also makes it possible to establish an average speed and therefore predict an estimated time of arrival. Google can determine an average speed by calculating the distance between destinations and the time it took you to arrive. By associating a GPS tracking device to your current location, Google can use local speed limits and the time between locations to establish real-time traffic movements.
Over a period of time, Google can utilize historical traffic patterns to predict average speeds during certain times of the day. This feature enables more effective planning for future trips. Like other applications that provide users with real-time traffic, Google encourages users to submit live route updates by reporting a navigation incident.
