先来看两个问题：路线规划与导航有什么差别？步行导航与驾车导航有什么差别？
回答：
1、路线规划，指的是为用户提供3条路线推荐。【高德】在提供路线规划的时候，会提供用户自己定义路线规划功能，这是别家没有做到的。导航。指的是为驾车用户提示路口信息，向左向右。进入匝道等信息。
2、我们这里说的步行导航和驾车导航，严格的说，应该是路线规划。从A地到B地，假设是驾车，路线规划会将公路路网做为搜索数据；假设是步行。过街天桥、地下通道、人行道做为搜索数据。
——————————————————————————————————-
一、路线规划——驾车
1、驾车路线规划
有三种策略，各自是最短时间、最少费用、最短路径、规避拥堵（參考了实时交通数据，这个比較NB）。
LEAST_TIME，LEAST_FEE, LEAST_DISTANCE,REAL_TRAFFIC
我们在这里採取驾车插件来做。代码：
//驾车导航
function driving_route() {
clearMap();
mapObj.plugin(["AMap.Driving"], function() {
var DrivingOption = {
policy: AMap.DrivingPolicy.LEAST_TIME
};
MDrive = new AMap.Driving(DrivingOption); //构造驾车导航类
AMap.event.addListener(MDrive, "complete", driving_routeCallBack); //返回导航查询结果
MDrive.search(start_xy, end_xy); //依据起终点坐标规划驾车路线
});
}
示意图：
2、驾车最后一公里步行
在最開始一段，和最后一段步行距离的时候，能够用虚线来表示。
代码：
//起点到路线的起点 路线的终点到终点 绘制无道路部分
var extra_path1 = new Array();
extra_path1.push(start_xy);
extra_path1.push(steps[0].path[0]);
var extra_line1 = new AMap.Polyline({
map: mapObj,
path: extra_path1,
strokeColor: "#9400D3",
strokeOpacity: 0.7,
strokeWeight: 4,
strokeStyle: "dashed", //虚线
strokeDasharray: [10, 5]
}); var extra_path2 = new Array();
var path_xy = steps[(steps.length-1)].path;
extra_path2.push(end_xy);
extra_path2.push(path_xy[(path_xy.length-1)]);
var extra_line2 = new AMap.Polyline({
map: mapObj,
path: extra_path2,
strokeColor: "#9400D3",
strokeOpacity: 0.7,
strokeWeight: 4,
strokeStyle: "dashed", //虚线
strokeDasharray: [10, 5]
});
效果图：
3、驾车导航拖拽效果
假设要可拖拽的效果，须要使用另外一个插件。AMap.DragRoute。
代码：
//可拖拽的驾车导航
function driving_route_drag(){
clearMap();
var path = [start_xy,end_xy];
mapObj.plugin("AMap.DragRoute",function(){
MDrive = new AMap.DragRoute(mapObj, path, AMap.DrivingPolicy.LEAST_FEE); //构造拖拽导航类
MDrive.search(); //查询导航路径并开启拖拽导航
});
}
示意图：

二、路线规划——公交
1、公交导航
公交导航不仅是路线相关的，还是依据公交车路线数据，进行查询。使用到插件AMap.LineSearch。
代码：
//公交线路查询
function lineSearch() {
clearMap();
//载入公交线路查询插件
//实例化公交线路查询类，仅仅取回一条路线
mapObj.plugin(["AMap.LineSearch"], function() {
var linesearch = new AMap.LineSearch({
pageIndex:1,
city:'北京',
pageSize:1,
extensions:'all'
});
//搜索“518”相关公交线路
linesearch.search('518');
AMap.event.addListener(linesearch, "complete", lineSearch_Callback);
AMap.event.addListener(linesearch, "error", function(e){alert(e.info);
});
});
}
效果图：
2、公交线路查询，如518
查询公交线路，须要注明城市。
每一个城市都可能有518路线。对吧。
代码：
//公交线路查询
function lineSearch() {
clearMap();
//载入公交线路查询插件
//实例化公交线路查询类，仅仅取回一条路线
mapObj.plugin(["AMap.LineSearch"], function() {
var linesearch = new AMap.LineSearch({
pageIndex:1,
city:'北京',
pageSize:1,
extensions:'all'
});
//搜索“518”相关公交线路
linesearch.search('518');
AMap.event.addListener(linesearch, "complete", lineSearch_Callback);
AMap.event.addListener(linesearch, "error", function(e){alert(e.info);
});
});
}
示意图：
3、通过网站，查公交线路
比方。我在北京东直门。想知道东直门都有哪些公交路线。
使用服务插件AMap.StationSearch。
代码：
//公交网站查询
function stationSearch() {
clearMap();
//载入公交网站查询插件
mapObj.plugin(["AMap.StationSearch"], function() {
//实例化公交网站查询类
var station = new AMap.StationSearch({
pageIndex: 1, //页码
pageSize: 10, //单页显示结果条数
city:'010' //确定搜索城市
});
station.search('东直门'); //查询
AMap.event.addListener(station, 'complete', stationSearch_CallBack);
AMap.event.addListener(station, 'error', function(e) {alert(e.info);});
});
}
演示样例图：
演示样例查看：http://zhaoziang.com/amap/zero_5_1.html
三、路线规划——步行
步行。能够过天桥啊，地下通道啊，穿过小区啊，不能走快速公路啊。等特点。
代码：
//步行导航
function walking_route() {
var MWalk;
mapObj.plugin(["AMap.Walking"], function() {
MWalk = new AMap.Walking(); //构造路线导航类
AMap.event.addListener(MWalk, "complete", walk_routeCallBack); //返回导航查询结果
MWalk.search(start_xy, end_xy); //依据起终点坐标规划步行路线
});
}
效果图：

四、小结
驾车，公交，步行的差别
1、从效果图里能够看出。这三种路线规划是搜索的不同数据库。
2、他们的服务插件不一样，都是通过【高德服务插件】进行调用。比原生API接口封装得更加完好，使用起来更加简单。
