This algorithm pretends to solve the efective route of public transport or privated routes.

Installation

npm install --save qruta-calcular

Usage

const calculate = require("qruta-calcular");

await calculate({rutas: arrayOfRoutes, config: configuration, origen: startLocation, destino: endLocation, area: area, qty: Quantity});

rutas

array of all posible routes Example:

[
    {
        "id":"routeId",
        "area":{
            "1":[[lat,lng]]
        },
        "distances":[
            0,
            23
        ],
        "path":[
            [lat,lng,stop]
        ],
        "name":"routeName",
        "company":"companyName",
        "details":"routeInfo",
        "osisp":true
    }
]

• id: Unique id of the route
• area: Object of polygons for the range of the route.
• distances: Array of distances of the path, example: [0, 25,75] starting allways with 0, 25 meters is the distance between the first location and the second location of the path plus the distance of the previous location (25 + 0 = 25), 50 meters is the distance between the second location and the tirth location of the path plus the distance of the previous location (50 + 25 = 75).
• path: array of array with [lat,lng,stop(optional)] of the route path.
• osisp: Only Stop In Some Places, boolean true | false, default false, if true it will use only locations with stop of the current path.
• name: Name of the route.
• company: Name of the company.
• details: Aditional info about the route.

config

Object of configutation Example:

{
  "walkInterval": 500,
  "avgError": 0.3,
  "proportion": 10,
  "walkingDistance": 200,
  "busSpeed": 45
}

• walkInterval: Distance between areas
• avgError: Average percentage of error.
• proportion: This makes more or less important the walking distance.
• walkingDistance: Distance to walk between 2 routes.
• busSpeed: Average bus speed, this will help to get the average time.

origen

The origin location in [lat,lng]

destino

The destiny location in [lat,lng]

area

Number of the area to search

qty

Number of maximun responses
