如何在openlayer 3中开发道路

var map = new ol.Map({
  target: 'map-container',
  layers: [
    // 添加地图图层
  ],
  view: new ol.View({
    // 设置地图初始视图
  })
});

var roadLayer = new ol.layer.Vector({
  source: new ol.source.Vector({
    url: 'path/to/road/data.geojson',
    format: new ol.format.GeoJSON()
  })
});

map.addLayer(roadLayer);

var interactions = ol.interaction.defaults().extend([
  // 添加其他交互控件
]);

map.addInteraction(interactions);

var roadStyle = new ol.style.Style({
  stroke: new ol.style.Stroke({
    color: 'blue',
    width: 2
  })
});

roadLayer.setStyle(roadStyle);

var view = new ol.View({
  center: ol.proj.fromLonLat([longitude, latitude]),
  zoom: 10
});

map.setView(view);
