Austin's Vision Zero & the High-Injury Network

Austin's Vision Zero initiative, adopted in 2015, identifies a "High-Injury Network" — a small subset of streets that account for a disproportionately large share of serious-injury and fatal crashes in the city. According to the City of Austin, the High-Injury Network "includes just 8% of the city's street network but contains nearly 60% of all serious injury or fatal crashes for all modes." If you were hit on a HIN corridor, that classification changes what evidence is most worth preserving and how a personal-injury claim gets framed. It does not, by itself, establish municipal liability for the road — Texas sovereign immunity, the Texas Tort Claims Act, and proximate-cause doctrine still apply. This page explains where Austin crashes concentrate, what the City's own data does and does not prove, and how to preserve the evidence that matters most when a crash happens on a documented high-risk corridor.

Where Austin crashes concentrate

The City of Austin's Vision Zero analysis identifies its High-Injury Network as the corridors where serious-injury and fatal crashes concentrate. The headline finding from the City's Vision Zero page: the HIN "includes just 8% of the city's street network but contains nearly 60% of all serious injury or fatal crashes for all modes." That stat is the policy hook for the entire program — if a small share of streets generates most of the harm, capital investment goes there first.

The HIN is built from a decade of crash records the City and TxDOT report into the Texas Department of Transportation Crash Records Information System (CRIS), plus City of Austin Police Department crash reports. The combined dataset is published on the Austin Open Data Portal; check the portal's Terms of Use page for current license details on the specific dataset before reusing the records.

The corridors that consistently show up on the City's HIN reflect a familiar mix: state highways like I-35 and US-183 that move a large volume of vehicles at higher speeds; major City arterials like East Riverside Dr, South Lamar Blvd, South Congress Ave, and Slaughter Lane that carry mixed-mode traffic through dense neighborhoods; and intersections of those arterials where pedestrians and cyclists meet motor vehicles. The City updates the HIN periodically as new data lands and capital projects come online.

The corridor table below summarizes a sample of HIN-classified roads, the source signals that flag them as high-risk, the evidence specific to that corridor type that's most useful in a claim, and the legal nuance that affects how a claim against any government entity gets framed. The list is not exhaustive — the live HIN map at austin.maps.arcgis.com shows current classifications.

What the City data says

Vision Zero is a policy framework that treats every traffic death as preventable. The City of Austin adopted it in 2015 and has built out the HIN analysis as one of its primary tools for prioritizing where to spend capital dollars. The data sources behind the HIN are reasonably well-defined: City of Austin Police Department crash reports, TxDOT Crash Records Information System (CRIS) entries, and supporting City inventories of road conditions, signal configurations, and pedestrian and cyclist counts.

The City's analysis covers all "modes" — passenger vehicles, motorcycles, pedestrians, cyclists, and increasingly micro-mobility (scooters and e-bikes). A finding the analysis surfaces consistently: pedestrians and motorcyclists are overrepresented in the serious-injury and fatal subset relative to their share of total trips. That's part of why the policy emphasizes intersections, signal-phase timing, and pedestrian crossings over generic vehicle-throughput improvements.

What the data does NOT do, on its own, is decide causation in any particular case. The HIN map shows where crashes concentrate; it does not show why your specific crash happened. A corridor can carry an HIN classification because of vehicle volume alone, or because of pedestrian/cyclist density, or because of intersection design, or because of a documented signal-timing problem. Each of those underlying factors matters in a different way for a personal- injury claim, and the same corridor can carry different risk profiles for different modes.

The City publishes the underlying crash-records dataset on its Open Data Portal. Specific license terms are documented at the portal's Terms of Use page; that's the right place to check before reusing the records, because license assignment can vary by dataset. Either way, the City's own warranty disclaimer applies — the City explicitly does not warrant "specific accuracy or completeness." That disclaimer should not be confused with a finding that the data is unreliable; it is a standard public-data-release posture.

Why it matters for your case

A HIN classification on the corridor where you were hit is useful context for several reasons. It positions the corridor as documented high-risk in the City's own analysis, which can support a negligence framing in a third-party liability claim — particularly if the at-fault driver was familiar with the corridor and its known hazards. It can help reconstruct sequence: traffic patterns, sight lines, pedestrian density, and signal timing on a HIN corridor are typically better-documented than on a low-volume residential street. Insurance adjusters who handle Austin crashes know which corridors are HIN- classified, which positions a represented claimant in a more informed conversation about liability and damages.

What HIN context does not do is establish that any particular driver or any particular government entity caused your specific crash. The factual chain from "this is a documented high-risk corridor" to "this person breached a duty that proximately caused your injury" still has to be built. HIN classification is one piece of supporting context, not the whole case.

There is one practical implication that often gets overlooked: HIN corridors typically have more cameras (City traffic cams, business security cameras, dashcams in regular commercial traffic), more witnesses (pedestrians and cyclists are overrepresented), and more secondary documentation (delivery records, ride-share trip logs, transit surveillance). If you were hurt on a HIN corridor, evidence preservation is materially easier than on a residential side street — but only if you act on it within the first 24 to 72 hours before recordings get overwritten and witnesses' memories fade.

For a represented claimant, the most useful application of HIN data is in the demand letter and in deposition preparation. A letter that cites the corridor's HIN classification, the specific evidence preserved from your crash, and the at-fault driver's familiarity with the corridor reads materially differently from a generic demand. It signals that you understand the corridor and have been deliberate about evidence.

Preserving evidence on a HIN corridor

The first hour after a crash on a HIN corridor is when the most useful evidence either gets captured or lost. A short list, in priority order:

Time-stamped photos of the scene. Lane markings, signal phase if a signal was involved (catch the actual phase you remember from before the crash before it cycles), road surface conditions, any visible debris, the position of all vehicles before they're moved, sight-line obstructions (parked cars, construction barricades, foliage). Photo timestamps are critical — modern phones embed them automatically; do not edit photos after the fact.

Witness contact information. HIN corridors carry higher pedestrian and cyclist density, which means independent witnesses are more available than on a residential street. Get phone numbers and emails from anyone who saw the crash. Ride-share drivers, delivery couriers, and transit operators are particularly useful witnesses because their work is documented (trip logs, GPS records).

Dashcam footage. If you had a dashcam, preserve the file immediately. Dashcams typically loop and overwrite; an un-preserved clip can disappear in hours. If another driver near you had a dashcam, ask politely before they leave the scene — most drivers will share a clip if asked at the scene.

Witness affidavits, eventually. Witness phone numbers are step one; written affidavits taken within a few weeks while memories are fresh are step two. A lawyer can help here, but informal written statements (texted, dated, signed) are useful even before formal involvement.

Signal timing and signage records. If a signal was malfunctioning, if a sign was missing or obscured, or if construction was affecting the corridor, those facts are documented somewhere (City work orders, TxDOT incident logs, contractor permits). Preserving the date and approximate location lets a records request later pull the right documents.

Don't post on social media. Anything you post about the crash, your injuries, or even general life activity in the days following becomes discoverable. Set accounts to private and stop posting until your case resolves. This is a comparative-fault concern as much as an evidence concern.

Don't give a recorded statement to the OTHER driver's insurer. Your own insurer's cooperation clause requires you to talk to your own adjuster, but the at-fault driver's adjuster has no claim on your statement. Recorded statements early in a claim are routinely used to lock you into a version of events before all the facts are clear.

What HIN data does NOT prove

The most common misreading of HIN data is to assume that a crash on an HIN corridor automatically supports a claim against the City of Austin or TxDOT for the corridor's design or maintenance. It does not, for several reasons.

HIN is statistical, not causal. A corridor can be on the HIN because of vehicle volume alone — high-volume corridors generate more crashes simply because more crashes happen where more driving happens. HIN classification by itself does not prove that the road's design or maintenance contributed to any particular crash. The factual chain from "crashes happen here often" to "the road caused YOUR crash" still has to be built with corridor-specific evidence.

Sovereign immunity covers most government-entity claims. The Texas Tort Claims Act (Chapter 101 of the Civil Practice and Remedies Code) waives governmental immunity only in narrow circumstances. Most highway-design claims against TxDOT face design-immunity defenses; most City-roadway claims face the discretionary-functions and design-immunity defenses; both face strict notice requirements that can bar a claim filed even one day late.

The Austin charter sets a 45-day notice deadline, with one important exception. The Texas Tort Claims Act sets a six-month state default for notice of claim, but Tex. Civ. Prac. & Rem. Code §101.101(b) preserves city charter provisions. The City of Austin's charter requires written notice of claim within 45 days of the incident. The statute also has an actual-notice escape hatch: §101.101(c) provides that the formal-notice requirements do not apply if the governmental unit has actual notice that death, injury, or property damage has occurred. Actual notice is not the same as formal notice and is fact-specific (it generally requires the governmental unit to have subjective awareness of its alleged fault, not just awareness that an incident happened), but it occasionally rescues claims that miss the 45-day deadline. Treat the 45-day deadline as the practical rule and the actual- notice exception as a fallback to discuss with a lawyer immediately if any government vehicle was involved or if road design was a factor.

Proximate cause is corridor-and-crash-specific. Even when sovereign immunity is waived, a claim still has to prove that the specific government conduct proximately caused the specific injury. A corridor's HIN classification is supporting context, not proof of cause-in-fact.

HIN does not freeze in time. The HIN map updates as new data lands and as capital improvements are completed. A corridor that was on the HIN three years ago may no longer be classified that way after signal-timing changes or lane reconfigurations. The version of the HIN that matters for your specific crash is the version active on the date of the crash, not the version live when you read this article.

The practical posture: HIN data is useful, but it is supporting context. A crash on a HIN corridor still requires the same factual building-blocks as a crash anywhere else — at-fault driver identification, comparative-fault analysis, evidence preservation, and (if a government entity is involved) strict adherence to notice and procedural rules. Treat HIN classification as a reason to be more deliberate about evidence preservation and corridor context, not as a substitute for the elements of the claim.
