Implementing pre-emption can aid in achieving it. EVs get unobstructed movement via pre-emption, usually by altering traffic signals and giving a green wave throughout the route. This approach of absolute pre-emption effects adversely on regular traffic by imposing unnecessary waiting. In this paper, we propose a novel emergency vehicle pre-emption (EVP) algorithm implemented in the Vehicular Ad-hoc Network (VANET) that can reduce the imposed undesirable waiting time, but still ascert","authors_text":"Roopak Sinha, Subash Humagain","cross_cats":["cs.NI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.soc-ph","submitted_at":"2021-07-09T02:48:07Z","title":"Routing Emergency Vehicles in Arterial Road Networks using Real-time Mixed Criticality Systems*"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2109.03210","kind":"arxiv","version":1},"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:b4695a296ceb03e20da8f899d3dd77394a200e905b434513bf5e3b94e0cf8b61","target":"record","created_at":"2026-07-05T03:12:24Z","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":"03d258278b9ae90d817ec37c683c7f7210401c283d4625a095a017fa9b8f6df6","cross_cats_sorted":["cs.NI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.soc-ph","submitted_at":"2021-07-09T02:48:07Z","title_canon_sha256":"b8095baad2288799c61a4bc6705d59914fa71893d92abc1ed82cab2321f117db"},"schema_version":"1.0","source":{"id":"2109.03210","kind":"arxiv","version":1}},"canonical_sha256":"ef390865c85919710e690a177d35b0a522e318da5a6408e4111035e42213ca96","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ef390865c85919710e690a177d35b0a522e318da5a6408e4111035e42213ca96","first_computed_at":"2026-07-05T03:12:24.815312Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:12:24.815312Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"FXulh3bMF1qCKi4E/XnmsXiZ0JzXGQ96csIkTe9/9PEZpIwDERUbJaEljM2DxxFkEqVNEYkSgn84n6jA4m5ZCA==","signature_status":"signed_v1","signed_at":"2026-07-05T03:12:24.815721Z","signed_message":"canonical_sha256_bytes"},"source_id":"2109.03210","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b4695a296ceb03e20da8f899d3dd77394a200e905b434513bf5e3b94e0cf8b61","sha256:4504258486fc301ad2184ed6779a739e422b4aaf3db012937ba36279ee758837"],"state_sha256":"d85c98bf687344e420de2c3f9270e14747f4fc622ab92a88ae15ecd54f1fe2b3"}
