Traffic with waze in Domoticz

[bricololo]

Hello, there is a new API for Waze traffic.
https://www.waze.com/row-RoutingManager/routingRequest?
I am looking to get travel time Home - Work with this request.

Actually, I can get an XML file via the request,
(for me, latitude and longitude are reversed)
https://www.waze.com/row-RoutingManager ... LOW_UTURNS

It is possible to have the answer in XML or JSON, modify returnXML=true by returnJSON=true
<summary time = "9264" must be divided by 60 for take the time.

I would like to create a script in shell or python to have the traffic.
This value will be displayed in Domoticz with a JSON request and just put this script in CRON.

There is sources

https://github.com/Nimrod007/waze-api/b ... /route.php

If anyone can realize the scripts before me it's will be good.
Thanks

Nice idea
I wouldn't put in into domoticz do.
Quickly created a page on my site, bookmark it on my phone

I'm wondering how much request you may sent to that service

Offcourse with something like this you could also easily drop in into a text virtual switch.

Code: Select all

<?php
header('Content-Type: text/html; charset=UTF-8'); 
function traffic($startlat, $startlon, $endlat, $endlon) {
	GLOBAL $traffic;
	$traffic=file_get_contents('https://www.waze.com/row-RoutingManager/routingRequest?from=x%3A'.$startlon.'+y%3A'.$startlat.'&to=x%3A'.$endlon.'+y%3A'.$endlat.'&at=0&returnJSON=true&timeout=60000&nPaths=1&clientVersion=4.0.0');
	$traffic=json_decode($traffic,true);
	$tijd=0;$lengte=0;
	foreach($traffic['response']['results'] as $street) {
		$tijd = $tijd + $street['crossTime'];
		$lengte = $lengte + $street['length'];
	}
	$tijd = strftime("%k:%M:%S",$tijd);
	$lengte = round($lengte / 1000,0);
	return array('tijd' => $tijd, 'lengte' => $lengte);
}

$hw = traffic(50.892565,3.114135,50.877122,4.164326);
echo 'Home - Work = '.$hw['tijd'].' / '.$hw['lengte'].'km<br>';
$wh = traffic(50.877122,4.164326,50.892565,3.114135);
echo 'Work - Home = '.$wh['tijd'].' / '.$wh['lengte'].'km<br>';

Wake is super!! Maybe the output can be written to a virtual text switch.

[Egregius]

Offcourse. Just add something like this:

Code: Select all

<?php
$idx = 153;//IDX of the virtual text switch
file_get_contents('http://ip:port/json.htm?type=command&param=udevice&idx='.$idx.'&nvalue=0&svalue='.$hw['tijd'])

It's interesting but I don't use a web server, so no php script.
That's why I'd like a shell script or python.
The hardest for me is to extract the time value of the answer to the request.
Thank for your answer

[Egregius]

You can use php without webserver;)

[bricololo]

Yes...
It's works
Thanks a lot

[Egregius]

You're welcome

Add the script to crontab so it runs every 5 minutes or something.

[bricololo]

I don't understand,
Travel times are increased by an hour.
For a normal time 18min, I get 1 hour 18 min.
For a normal time 1 hour 30 min, I get 2 hour 30 min.

Is possible to decrease an hour.
I tried
$timestamp = mktime($tijd);
$timestamp -= 3600;
$tijd = date($timestamp);
but it's not works

Thanks

[Egregius]

Yes, I noticed that also...

Try

Code: Select all

$tijd = strftime("%k:%M:%S",$tijd-3600);

strftime uses UTC or DST or something. If it's going to be a problem after wintertime I'll search for another function.

[bricololo]

Super,
Thanks, I'm not good in php.

[remb0]

maybe a nice for the wiki. a little tutor how to schedule, run configue and see it in domoticz?

Hello

I simplified the script in order to get only the time (every 10 minutes) for my trip home -> work
And I populate a "pressure" sensor to get the best timing to leave home (before 8h10 in my case)



Here is the code (quite the same) :

Code: Select all

---------------------------------
-- Script de calcul de temps pour un trajet entre 2 coordonnées
-- Auteur : Neutrino (updated iero)
-- Date : 7 septembre 2015 (updated 21/09/2015)
-- Nécessite un capteur virtuel de type Pression
-- source :
-- http://www.domo-blog.fr/info-trajet-waze-eedomus-version-raspberry/
---------------------------------
commandArray={}

time = os.date("*t")
if((time.min % 10)==0) then

        --import des fontions pour lire le JSON
        json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")()
        --variables à modifier----------------
        --idx du capteur
        idx = 'XX'
        --coordonnées de départ
        departx="X.XXX"
        departy="X.XXX"
        --coordonnées d'arrivée
        arrivex="X.XXX"
        arrivey="X.XXX"
        --Récupération du trajet et de sa durée en temps réel via WAZE--
        ----------------------------------------------------------------
        local waze=assert(io.popen('curl "https://www.waze.com/row-RoutingManager/routingRequest?from=x%3A'..departx..'+y%3A'..departy..'&to=x%3A'..arrivex..'+y%3A'..arrivey..'&returnJSON=true&timeout=6000&nPaths=1&options=AVOID_TRAILS%3At%2CALLOW_UTURNS"'))
        local trajet = waze:read('*all')
        waze:close()

        local jsonTrajet = json:decode(trajet)

        --Noms des principales routes empruntées
        routeName = jsonTrajet['response']['routeName']
        --Liste des routes empruntées
        route = jsonTrajet['response']['results']

        --calcul du temps de trajet (en secondes)
        routeTotalTimeSec = 0
        for response,results in pairs(route) do
           routeTotalTimeSec = routeTotalTimeSec + results['crossTime']
        end

        --Temps de trajet en minutes
        routeTotalTimeMin = routeTotalTimeSec/60-((routeTotalTimeSec%60)/60)

        --print(routeTotalTimeMin)
        commandArray[1]={['UpdateDevice'] =idx..'|0|' .. tostring(routeTotalTimeMin)}
end

return commandArray

Next step, I would like to receive an alert if waze see a police control on this trip..

Hi iero !

I just tried your lua script but i haave this error :
2015-09-28 11:48:10.576 Error: EventSystem: /home/pi/domoticz/scripts/lua/script_time_WAZEFLO.lua:35: attempt to index local 'jsonTrajet' (a nil value)

Any idea ?

My data are :
--coordonnées de départ
departx="48.632936"
departy="2.291525"
--coordonnées d'arrivée
arrivex="48.796156"
arrivey="2.299969"

Very nice!

[remb0]

there is an link to JSON.lua (for the calsulations) you miss that file!

download: http://regex.info/code/JSON.lua
and place it in the right folder.

[Whatsek]

I have the same error, I have the JSON.lua from you link, and put in /home/pi/domoticz/scripts/lua/JSON.lua

Do I have to edit something in that file? I couldn`t find anything about "trajet"

[Derik]

pffff I cannot handle all the great options ij Domoticz....[ like that ]

Is there perhaps a clean and working code example for Waze?
Or a Wiki?

[salvation]

Yes, I noticed that also...

Try

Code: Select all

$tijd = strftime("%k:%M:%S",$tijd-3600);

strftime uses UTC or DST or something. If it's going to be a problem after wintertime I'll search for another function.

Thanks for this script Egregius, works great.
I've also tried the LUA variant but it's not working. Get the same message as others. Seems the call to waze is not correct and returns an empty result. But I didn't know how to fix.

[Egregius]

Once you go PHP you'll never look back to lua
