Stupid little command line utility to give the ETA to work/home for various times in the future.

eta.py

import requests
import datetime
import time
import urllib 
import sys

origin = "1234 Main Street, Anywhere CA 12345"
dest   = "4567 Corporation Way, Anywhere CA 12345"
key    = "your-api-key-for-distance-matrix"
time_spans = range(0, 61, 15)

if len(sys.argv) > 1 and sys.argv[1].lower() == 'work':
    (origin, dest) = (dest, origin)

def unix_to_hm(u):
    return datetime.datetime.fromtimestamp(u).strftime("%H:%M")

now = int(time.time())
now_dt = datetime.datetime.fromtimestamp(now)
now_hm = now_dt.strftime("%H:%M")

results = []
for offset in time_spans:
    departure_time = now + offset * 60
    uri = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=%s&destinations=%s&key=%s&departure_time=%s&traffic_model=best_guess" % (urllib.quote(origin), urllib.quote(dest), key, str(departure_time))
    rv = requests.get(uri)
    results.append([ departure_time, rv.json() ])

for row in results:
    traffic = row[1]['rows'][0]['elements'][0]['duration_in_traffic']['value']
    print "%-6s: arrive %-6s traffic %2.2f" % (unix_to_hm(row[0]), unix_to_hm(row[0] + traffic), int(traffic/60))

Example output:

11:36 : arrive 11:57  traffic 21.00
11:51 : arrive 12:13  traffic 22.00
12:06 : arrive 12:28  traffic 21.00
12:21 : arrive 12:42  traffic 21.00
12:36 : arrive 12:57  traffic 21.00
