US California H3 Travel Matrix
收藏资源简介:
Uber's H3 spatial grid. It answers a single, expensive question instantly: how long does it take, and how far is it, to travel between places in California? <p><br/></p> Every OD pair is keyed by H3 cell (resolution 7, ~5 km² hexagons), so you can join it directly to any H3-indexed table or roll it up with native Snowflake H3 functions, no routing engine, no API rate limits. <p><br/></p> **What's inside** - ~2.21 billion loaded origin-destination pairs - 34,929 origin cells x 65,128 destination cells covering California - Travel time (seconds) and road travel distance (meters) for each pair - H3 resolution 7 indexing (origin + destination) - Pre-computed on the road network, not straight-line distance <p><br/></p> **Use it for** - Logistics & fleet: service-area sizing, depot/hub placement, delivery zone design - Site selection & retail: drive-time catchments for any location in seconds - Accessibility analysis: reach to hospitals, stations, stores, jobs - Pricing & coverage: distance/time-based pricing models, SLA feasibility <p><br/></p> **Why H3** Because the grid is fixed and standard, you can join this matrix to demographics, sales, sensor, or any other H3-tagged dataset and get answers with a single SQL JOIN, and visualize the result instantly on a map.

基于Uber H3网格预计算的加利福尼亚州起终点出行时间与距离矩阵。可快速回答加利福尼亚境内任意两地之间的出行时长和距离,无需路由引擎或API。
核心内容
- 数据规模:约22.1亿条起终点(OD)对。
- 覆盖范围:34,929个起点单元 × 65,128个终点单元,覆盖整个加利福尼亚州。
- 数据字段:包含出行时间(秒)和道路行驶距离(米)。
- 网格系统:H3分辨率7(约5 km²六边形)索引,起点和终点均使用H3编码。
- 计算方式:基于实际道路网络预计算,非直线距离。
适用场景
- 物流与车队:服务区范围测算、仓库/枢纽选址、配送区域设计。
- 选址与零售:任意地点的驾车时间缓冲区分析。
