VRU SIMULATION SERVER AND WEB VIEW. Skeleton Go, HTML + Javascript with open street map ...
Install Golang on your computer https://golang.org/
To run locally, build and run server.
Enter localhost:8081 in your browser
Simple sequence
The simulation tool should generate data in JSON format such as:
Example output
{
"vru-simulation-data":{
"name": "simdata-example",
"simdata": [
{
"routename": "pastoria avenue",
"gps": [{"lat": 37.386339,"long": -122.040848},{"lat":37.384997,"long":-122.034524}],
"vrus": [{"type":"BIKE","number":5},{"type":"PEDESTRIAN","number":5}]
},
{
"routename": "south pastoria avenue",
"gps": [{"lat": 37.386239,"long": -122.30848},{"lat":37.382997,"long":-122.03433524}],
"vrus": [{"type":"BIKE","number":2},{"type":"PEDESTRIAN","number":3}]
}
]
}
}
The json structure should be handled by the server and serve as input for the simulation tool. View the above JSON as an example which has room for improvement.
- The json included a user identified name : "simdata-example" , useful for storage server side.
- each route should have a user identified name : "routename":"pastoria avenue"
- the gps coordinates for the route from A to B. "gps":["lat": 37.1111,"long": -122.111,...]
- the various VRUS that will be simulated for that route: "vrus": [{"type":"BIKE","number":2},{"type":"PEDESTRIAN","number":3}]
The above examples have identified two road users(BIKE,PEDESTRIAN). We need to add more road users and name them accordingly.
For inspiration look at: https://docs.mapbox.com/api/navigation/#directions
Current example should let a user set a route from the hardcoded centre of the map.
go build main.go
./main
enter in your browser:
http://localhost:8082
To see the requestdata add a breakpoint in developer mode in the browser at row 48 and click on the map for a new route.
map.getSource('route').setData(geojson)
inspect the geojson object and you will see all the geocoords for a new route. That will be used to build the json data above.
