"Break down USRN {usrn} into its component road links for routing analysis. "

"restriction_matching_analysis": (
"Perform comprehensive traffic restriction matching for road network in bbox {bbox} with SPECIFIC STREET IDENTIFICATION. "
"Step 1: Build routing network: get_routing_data(bbox='{bbox}', limit={limit}, build_network=True) "
"Step 2: Extract restriction data from build_status.restrictions array. "
"Step 3: For each restriction, match to road links using restrictionnetworkreference: "
" - networkreferenceid = Road Link UUID from trn-ntwk-roadlink-4 "
" - roadlinkdirection = 'In Direction' (with geometry) or 'In Opposite Direction' (against geometry) "
" - roadlinksequence = order for multi-link restrictions (turns) "
"Step 4: IMMEDIATELY lookup street names: Use get_bulk_features(collection_id='trn-ntwk-roadlink-4', identifiers=[road_link_uuids]) to resolve UUIDs to actual street names (name1_text, roadclassification, roadclassificationnumber) "
"Step 5: Analyze restriction types by actual street names: "
" - One Way: Apply directional constraint to specific named road "
" - Turn Restriction: Block movement between named streets (from street A to street B) "
" - Vehicle Restrictions: Apply dimension/weight limits to specific named roads "
" - Access Restrictions: Apply vehicle type constraints to specific named streets "
"Step 6: Check exemptions array (e.g., 'Pedal Cycles' exempt from one-way) for each named street "
"Step 7: Group results by street names and road classifications (A Roads, B Roads, Local Roads) "
"Return: Complete restriction mapping showing ACTUAL STREET NAMES with their specific restrictions, directions, exemptions, and road classifications. Present results as 'Street Name (Road Class)' rather than UUIDs."
