Korea Road Network ETA (v3)

16개 광역지자체 도로망 그래프. 시간대별 평균 통행속도(p50)가 부착되어 있어 ETA(예상소요시간) 산정·라우팅·배차 시뮬레이션에 바로 사용 가능합니다.

Contents

각 region 마다 self-contained 파일 두 개:

  • {region}_osm_v3_nodes.parquet — 노드 (node_id, lat, lon)
  • {region}_osm_v3_edges.parquet — 엣지 (source, target, length_m, highway, oneway, ktdb_matched, …, 시간대별 속도 컬럼)

Regions (16)

seoul, busan, daegu, incheon, gwangju, daejeon, ulsan, sejong, gyeonggi, gangwon, chungbuk, chungnam, jeonbuk, jeonnam, gyeongbuk, gyeongnam

Speed columns (8 slots × weekday/weekend)

스키마: {day_type}_{slot}_p50 (단위: km/h)

  • day_type ∈ {weekday, weekend}
  • slot
    • observed (KTDB 직접 관측): am_peak, midday, pm_peak, offpeak
    • derived (관측 4슬롯에서 도출): am_shoulder, afternoon, pm_shoulder, night

도출 규칙은 도로 위계 그룹별로 다른 가중치/계수를 사용 — 자세한 내용은 프로젝트 코드(phase_d_attach.py) 참조.

Quick start

import pandas as pd

nodes = pd.read_parquet("seoul_osm_v3_nodes.parquet")
edges = pd.read_parquet("seoul_osm_v3_edges.parquet")

# Edge travel time (sec) at AM peak
speed_kmh = edges["weekday_am_peak_p50"].clip(lower=5.0)
edges["tt_sec"] = edges["length_m"] / (speed_kmh * 1000 / 3600)

scipy 또는 networkx 등 일반 라우팅 라이브러리에 그대로 투입 가능합니다.

Provenance

  • Topology: OpenStreetMap (ODbL) — 2026년 추출
  • Speeds: 한국교통DB (KTDB) 링크별 시간대 통행속도 (2024년 관측)
  • Pipeline: phase_a (6시간 프로파일) → phase_b (regional fallback) → phase_c (위계 클립) → phase_d (attach + derived slots)
