我有一个geoJSON对象，我想在我的geoJSON文件中的路标之间进行路由。

我的问题是：我可以在文件中的位置和＃34之间进行路由;仅在这些属性为＆＃34;轮椅＆＃34;：＃34;是＆＃34;和＆＃34;公路＆＃34;：＆＃34;人行道＆＃34 ;.并且路由不能使用LineStrings，其中属性仅为＆＃34; highway＆＃34;：＆＃34; footway＆＃34;。
我可以使用mapbox方向服务吗？
我使用自定义属性创建了自己的openstreetmap，但知道我被卡住了，我不知道如何在该地图中路由，因为路由只能在这些方式上调用（线串和点）其中一个属性是轮椅=＆＃34;是＆＃34;。

您可以使用L.mapbox.FeatureLayer与过滤器一起呈现您的featurecollection：
var featureLayer = L.mapbox.featureLayer('data.geo.json').addTo(map);
var filter = function (feature) {
// Check if feature is a linestring
if (feature.geometry.type == 'Linestring') {
// Check if has property wheelchair and value is yes
if (feature.properties.hasOwnProperty('wheelchair') &&
feature.properties.wheelchair === 'yes') {
// Check if has property highway and value is footway
if (!feature.properties.hasOwnProperty('highway') ||
feature.properties.highway === 'footway') {
// highway absent or highway is footway
return true;
} else {
// highway found and value is not footway
return false;
}
} else {
// Wheelchair absent or value isn't yes
return false;
}
} else {
// Not a linestring
return true;
}
}
featureLayer.on('ready', function () {
featureLayer.setFilter(filter);
});
