Freight Highway Network

The DVRPC Freight Highways data layer was based on DVRPC's major routes dataset representing major highways in the region. The dataset uses the centerlines of undivided highway segments and ramps to depict each of the major freight serving highways as identified by DVRPC staff. The highways are limited to regional serving routes including interstates and limited-access highways. This dataset is mapped by route name number and is segmented at key interchanges and by several characteristics: road profile, V/C ratio and performance indicators.

DVRPC货运高速公路数据图层基于DVRPC用于表征本区域主要高速公路的主路线数据集构建而成。该数据集采用非分隔高速公路路段与匝道的中心线，对DVRPC工作人员识别出的所有主要货运服务高速公路进行可视化呈现。此类高速公路仅限区域服务类路线范畴，包含州际公路与限制通行高速公路。该数据集依据路线名称与编号进行制图，并在关键互通式立交处结合多项特征进行分段，特征涵盖道路线形、交通量-通行能力比（V/C ratio）以及性能指标。
