RoadRunner Asset Mapping

Consolidated lookup tables for mapping source map format elements to RoadRunner project asset paths. All paths are relative to the project Assets/ folder.

When to Use

• Resolving lane marking subtypes to RoadRunner .rrlms asset paths
• Mapping sign codes (US MUTCD, German StVO, Japanese) to sign asset SVGs
• Looking up barrier/extrusion asset paths for fence, guard rail, jersey barrier, wall
• Finding prop/static object asset paths for placement in RRHD
• Determining region-specific sign paths based on geoReference coordinates
• Assigning lane type enums from source format lane classifications

When NOT to Use

• Building RRHD objects from scratch, use roadrunner-rrhd-authoring
• Performing the full Lanelet2 conversion pipeline, use roadrunner-convert-lanelet2-to-rrhd
• Importing maps into RoadRunner, use roadrunner-import-scene

Key Rules

• All asset paths start with Assets/, always prefix when constructing RelativeAssetPath objects.
• Extension matters. .rrlms = lane marking style, .rrcws = crosswalk style, .rrpms = polygon marking style, .svg_rrx = sign. Using wrong extension causes "Asset file is missing" on import.
• Signs use .svg_rrx extension (NOT .svg). The .svg paths in XML configs are internal references only.
• Sign naming: descriptive English names with region suffix (e.g., Stop_JP_01.svg_rrx, MaxSpeedLimit_30_DE.svg_rrx). The old Sign_<code>.svg naming is obsolete.
• Region detection from geoReference. Use lat/lon to determine Japan/Germany/US for sign and marking paths.
• Runtime asset discovery is MANDATORY for signs. Asset names vary by version, always verify file exists before assigning.
