I have built an small application which calls the Google Directions API in Transit mode. It works - nevertheless it returns only one possible route, so it shows no alternatives. Usually I expect 3-4 options to choose from.
Example:
http://maps.googleapis.com/maps/api/directions/json?origin=bieberstrasse,+dusseldorf&destination=norf,+neuss&sensor=false&mode=transit&departure_time=1399399424
The returned JSON structure has the expected "routes" array, but this array always has only one element. I have tried it with addresses in Brazil and Germany - it doesn't matter the country, I only get one single route.
Did I miss some parameter? Could someone help me with it?
If you want alternative routes, specify the request parameter alternatives=true:
http://maps.googleapis.com/maps/api/directions/json?alternatives=true&origin=bieberstrasse,+dusseldorf&destination=norf,+neuss&sensor=false&mode=transit&departure_time=1399399424

For our use case, we need a turn-by-turn navigation on a mobile device but using a custom route.
Please let me know if the following usage scenario is possible:
Given an array of points (lat/long) that the route needs to pass through, get a route using CalculateRoute.
Create a deeplink for HERE WeGo (e.g. iOS) using the sequence of waypoints obtained in step #1
Navigate turn by turn in HERE WeGo along the route
So far I was successful in #1 but could not create a deeplink with the same route for HERE WeGo. When I create a link, the app simplifies the route to only include origin and destination points and omits all "via" points.
Would appreciate advice on this.
In general passing the waypoints one after the other should open the route with the intermediate points (at least on wego.here.com) , not so sure if this work out of the box in HERE WE Go https://developer.here.com/documentation/deeplink-web/dev_guide/topics/share-route.html
I am using a HERE API call to request traffic incident data from a particular start time. Whenever I include the "type" key and specify "Accident" as the value, no response is returned. However, switching the value to "Construction" does provide a response.
Does anyone have information on how to make the API call return accident data specifically?
Here is the exact call I am using:
https://traffic.api.here.com/traffic/6.3/incidents.json?app_id={{app_id}}&app_code={{app_code}}&startTime=2017-01-01T00:00:00-05:00&type=Accident&bbox=52.5233,13.4035;52.5181,13.4159
There is no data returned as there are no “Accident” type incidents in that location. This can be seen when skipping the “type” parameter:
https://traffic.api.here.com/traffic/6.3/incidents.xml?app_id=APP_ID&app_code=APP_CODE&startTime=2017-01-01T00:00:00-05:00&bbox=52.5233,13.4035;52.5181,13.4159
Traffic Data is dynamic data. Accident can be located somewhere and disappear in a matter of minutes. We recommend to use wego.here.com to locate an accident, or Bing maps (they are all using our services and traffic data).
We were able to find one in Germany right now (should be there until 13:34 German time):
https://traffic.api.here.com/traffic/6.3/incidents.xml?app_id=app_id&app_code=app_code&startTime=2017-01-01T00:00:00-05:00&prox=51.52427,11.85887,15&type=Accident
Hope this helps! Happy Coding!
I have searched the questions here and gone through a fair amount of the API. I have not found reference to requesting historic route data. My questions is this; Does the Here api support historical route data. An example request would be that I seek the mileage from point a to point b 365 days ago, when perhaps a key route obstruction existed such as a bridge was out or a road was closed for construction that resulted in more miles during that historic period.
I would like to answer this in two parts
Can a route be calculated for a past date ?
Yes, you can. You need to request a Time Aware Route like below. You can read more about it in the developer site.
`
GET https://route.api.here.com/routing/7.2/calculateroute.json
?app_id={YOUR_APP_ID}
&app_code={YOUR_APP_CODE}
&mode=fastest;car;
&waypoint0=geo!37.743385,-122.422835
&waypoint1=geo!37.743878,-122.423686
&departure=2014-03-12T10:00:00
&routeattributes=sh,bb,g
`
Will the map used for the query depend on the departure date ?
No, Here API always uses the current version of the map available unless you specify explicitly the map version. But you can specify only till previous two releases.
So for your question, you wont be able to get the map data for a past year even using map version. But what you can do, is explicitly avoid the bridge or road newly constructed so that the api doesn't suggest that route. You can do this through Custom Route Extension API like below example.
GET http://cre.api.here.com/2/overlays/upload.json
?map_name=OVERLAYBLOCKROAD
&overlay_spec=[{"op":"override","shape":[[50.10765,8.68774],[50.10914,8.68771]],"layer":"LINK_ATTRIBUTE_FCN","data":{"VEHICLE_TYPES":"0"}}]
&storage=readonly
&app_id={YOUR_APP_ID}
&app_code={YOUR_APP_CODE}
I am working on a school project in R where I am attempting to map where the most popular youtube videos are posted around the world. I am able to get the data for the 50 most popular videos, but am having trouble understanding how to use pageToken.
The current get request I am using is with the following:
https://www.googleapis.com/youtube/v3/videospart=snippet%2CrecordingDetails&chart=mostPopular&maxResults=50&key={api_key}
Is it possible to retrieve more than 50 results using "pageToken" (I am unfamiliar with how this works).
Any help would be appreciated thanks!
Videos: list
pageToken string The pageToken parameter identifies a specific
page in the result set that should be returned. In an API response,
the nextPageToken and prevPageToken properties identify other pages
that could be retrieved.
Note: This parameter is supported for use in conjunction with the
myRating parameter, but it is not supported for use in conjunction
with the id parameter.
So when you get the results from the first request you should have an option called page token if you send that to the next request
&pageToken=api_pageToken
it should give you the next bunch of rows.
Note: I am not an R programmer so I cant help with the code for a loop over the results to find out if there are page tokens or not.
Hi every one i am working on asp.net web routing. I need same url pattern without any constraints.
i need following multiple URL pattern.
"CountryRoute","{country_name}" "~/country.aspx" => www.abc.com/australia/
"PageRoute","{page_url}" "~/page.aspx" => www.abc.com/contact_us/
"keywordRoute","{keyword_url}" "~/keyword.aspx" => www.abc.com/keywordName/
i can't apply any constraints.
You can't have one common URL for two different resources (without magic, that is). That's like suggesting one road could take you to two different places.
You know that en URL is kind of the address of a web page, right? Consider the similar properties in comparison with a real address of a real house; It would be OK to have two addresses for one house, but if two different houses had the same address (in the same town, county, country etc.) then how would the postman be able to tell which house a certain letter should be delivered to?
If you wanted to, you could build your own route handling but that wouldn't change the fact that at one point or another you need to do the job of the postman and identify some unique feature of the request or its context, that points towards one resource or the other. It could be the querystring, a session object, whether the call was made from a computer i China or Germany or whatever -- you need to decide what makes sense in your case. "Both link going to different destination page but URL are same", as you wrote in your answer to my comment, does not.
