NA : Barriers

Question

Hello,

I am using the Network Analyst with the Rest API to perform routing in the FlexViewer application.

I would like the Routing solver to take into account Barriers. At the moment, I send barriers to the solver through the "barriers" parameter of the solvetask in Flex.

Now, I would like the Routing Solver to use barrriers stored in a  database table instead of loading barriers through the REST API. Is there a way to specify the barriers datasource so that the solver can get them "automatically"  ?

Many thanks for your help.

PS : I hope my english is not too bad....

Hi Juliano,

A one way to do it would be through creating a RDBMS view on top of the Feature Class and specify Order Clause on it. On the other hand, it might require some SDE skills. It also will not be dynamic enough, shell you decide to change sorting depending on the client requests.

On the other hand, I just discovered that there is a way to pass 3D input locations even to the 10.0 NAServer REST endpoint: to do it you need to pass X, Y, Z attributes on the Stops (you do not even have to specify "geometry" part), e.g.:{ 
"features"  : [
{
  "attributes" : {"X":481903.591, "Y":3768558.745, "Z":0}
},
{
  "attributes" : {"X":481849.220, "Y":3768533.156, "Z":9}
},
{
  "attributes" : {"X":481883.752, "Y":3768450.258, "Z":4.5}
}
]

Hope this will help,
Dmitry

Hi Again

I tried finding answers on forums and could not find, that is why I am asking here.

I have an network routing application for classroom scheduling that uses DataLayer as input for Stops.

I have a pre ordered sequence I want the route to be solved, for example MS-325, SS-1253, PF-4214, ENB-202, ES-718

When solving the route however it does not follow the sequence specified in the where clause. 
(BLD_ID = 'MS' AND RM_ID = '325') OR (BLD_ID = 'SS' AND RM_ID = '1253') OR (BLD_ID = 'PF' AND RM_ID = '4214') OR (BLD_ID = 'ENB' AND RM_ID = '202') OR (BLD_ID = 'ES' AND RM_ID = '718')
I understand it is following the Record Order the rooms are stored in the table. Also, I tried the ORDER BY statement but doesn�??t seem to have any effect.

Is there a way to order the Route Stops when using a Datalayer?

Thank you very much for all and any help.

Hi Juliano, Please take a look at the code below. In order to make it work, publish SanFrancisco tutorial MXD from ArcGIS 10.0 and change the value of the ROUTE_ENDPOINT variable in the code below accordingly: [HTML] Simple Routing
