Most existing algorithms and speed-up techniques work by computing subjourneys to intermediary stops until the destination is reached. In contrast, the trip-based model focuses on trips and transfers between them, constructing journeys as a sequence of trips. In this paper, we develop a speed-up technique for this model inspired by principles behind existing state-of-the-art speed-up techniques, Transfer Pattern and Hub Labelling. The resulting algorithm allows us to compute Pareto-optimal (with respect to arr","authors_text":"Sascha Witt","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-07-05T15:32:06Z","title":"Trip-Based Public Transit Routing Using Condensed Search Trees"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.01299","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5c394d9c75c756b296df72e2296ea3831143eacf178080ff118b6fc89202614a","target":"record","created_at":"2026-05-18T01:04:37Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"5b3af3955a71e657c4672a850849e8ca66d0b89e3411e394ff2b6fba6510ffd5","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.DS","submitted_at":"2016-07-05T15:32:06Z","title_canon_sha256":"75a7772c46d5bd6ec5592e6eef2a058afb1972ee3128831ecb1fd07d323d3906"},"schema_version":"1.0","source":{"id":"1607.01299","kind":"arxiv","version":2}},"canonical_sha256":"95b97e2459fddf83f31ee5b315d4d5bca983c74ec0ffec693b18d8fface3a54c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"95b97e2459fddf83f31ee5b315d4d5bca983c74ec0ffec693b18d8fface3a54c","first_computed_at":"2026-05-18T01:04:37.141540Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:04:37.141540Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rRJWCIbekEKnQdM5hLt511zIEo1U4AB97EWiF3LlgXETRp8QyqCEy9h3SsDKlPX5JF20q26jPVk94PgB9bbFBg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:04:37.142213Z","signed_message":"canonical_sha256_bytes"},"source_id":"1607.01299","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5c394d9c75c756b296df72e2296ea3831143eacf178080ff118b6fc89202614a","sha256:c648915f6516e1c7e8de47e128d0edea90267a9ccfa3c261ca5fbab52f93eaa1"],"state_sha256":"207e4bc813dfe04c5b8cc1c6b6234488ab745348166c9c30ff12b57ae7f8f7c6"}
