前言：旅游规划的技术革命
在数字化旅游时代，MCP2.0（Map-based Collaborative Planning）系统代表着旅游攻略技术的最新演进。作为对1.0版本的全面升级，MCP2.0通过深度整合高德地图API和智能算法，实现了从静态信息展示到动态智能规划的质的飞跃。本系统专为解决现代旅行者面临的三大核心痛点而设计：
- 信息过载：海量景点数据难以有效筛选和组织
- 规划低效：手动规划路线耗时费力且难以优化
- 实时应变：无法根据路况和突发情况动态调整行程

if (dayAttractions.length > 0) {
result.push({
day: currentDay,
attractions: [...dayAttractions],
totalHours: maxHoursPerDay - remainingHours
});
}
return result;
}
// 计算两点之间的距离（简化版，实际应使用高德API）
function calculateDistance(point1, point2) {
const R = 6371; // 地球半径(km)
const dLat = (point2.lat - point1.lat) * Math.PI / 180;
const dLon = (point2.lng - point1.lng) * Math.PI / 180;
const a =

policy: AMap.DrivingPolicy.REAL_TRAFFIC, // 考虑实时路况
showTraffic: true,
hideMarkers: true
});
// 转换路径坐标格式
const waypoints = path.slice(1, -1).map(point => ({
lnglat: [point.lng, point.lat]
}));
// 执行路径规划
driving.search(
[path[0].lng, path[0].lat],

const duration = route.time; // 单位：秒
const trafficCondition = getTrafficCondition(route.trafficStatus);
// 显示在UI上
document.getElementById('eta-distance').textContent = `${(distance / 1000).toFixed(1)} km`;
document.getElementById('eta-time').textContent = `${Math.floor(duration / 3600)}小时${Math.floor((duration % 3600) / 60)}分钟`;
document.getElementById('eta-traffic').textContent = trafficCondition;
document.getElementById('eta-traffic').className = `traffic-${route.trafficStatus.toLowerCase()}`;
