Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built from the bottom up, starting from vehicle production volumes by connectivity type and the attach rate at which automakers and fleet operators fit onboard units, then combining those unit counts with realised prices for onboard modules, roadside units and the underlying chipsets. Roadside deployment is sized separately from public transportation-agency procurement volumes and average unit costs for signal-connected infrastructure. The resulting build is checked against revenue disclosed by the connectivity-module and automotive-semiconductor suppliers named in this report, segment by segment. Where a supplier's disclosed revenue implies a different attach rate or unit price than the build assumed, the bottom-up assumption is corrected rather than averaged against the disclosed figure.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Primary interviews target the commercial and engineering roles that actually decide V2X sourcing: procurement and platform engineering leads at automakers and tier-one suppliers, product managers at connectivity-module and chipset vendors, and traffic-engineering or ITS officials at transportation authorities who specify roadside equipment. Distribution and channel contacts are included where a market is served through system integrators as well as direct OEM sales. Sampling weights toward North America, China and the European Union, since mandate timing and vehicle-program decisions in those geographies set the pace the rest of the market follows, with additional coverage in Japan and South Korea to capture platform decisions made outside the three lead markets.

Secondary sources, this report

Desk research draws on the FCC's 5.9 GHz spectrum-allocation dockets and equivalent European Commission and ETSI ITS-G5 filings, 3GPP release documentation covering cellular-V2X standards, and China's C-V2X industry-alliance technical specifications, since regulatory and standards timing drives most of the forecast. Vehicle production volumes come from national automotive-manufacturer association data, and shipment values for connectivity modules are cross-checked against customs classifications covering automotive telematics hardware. Annual reports and investor disclosures from the automotive-semiconductor and tier-one suppliers named in this report provide the revenue figures the bottom-up build is checked against.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built on staggered regulatory mandate timing across the three lead vehicle-producing regions, OEM platform refresh cycles that determine when connectivity becomes standard equipment, and a declining cost curve for cellular-V2X modules as production scales. Near-term growth is normalized for the pace at which national spectrum and standards decisions are actually finalized, since announced timelines in this market have historically slipped against actual rollout dates. For the forecast to hold, cellular standards need to remain the primary technology path in the largest vehicle-producing markets, and roadside infrastructure funding needs to keep pace with vehicle-side adoption, since onboard units depend on network coverage to function as intended.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs are back-tested against recorded shipment and revenue growth for the 2020 to 2024 period to confirm the build reproduces historical trend before it is extended forward. Segment-level shifts, including the pace at which cellular connectivity overtakes dedicated short-range hardware and the share commercial vehicles gain against passenger cars, were reviewed against the same supplier disclosures used in sizing to confirm the direction and rough pace of each shift is consistent with what those companies report. Sensitivities were run on the two assumptions the forecast depends on most: the timing of spectrum and standards finalization in the largest markets, and the pace of module cost decline, since both move the outcome more than any other single input.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest for onboard-unit sizing in North America, China and the European Union, where mandate timing is public and supplier shipment data is disclosed with enough regularity to cross-check the build directly. It is thinner for roadside-unit deployment outside those three markets, where procurement is fragmented across municipal and regional authorities and reporting is inconsistent, and for the Others category within connectivity type, which spans legacy and transitional hardware with little standalone disclosure. A structural risk to the estimate is a slower-than-assumed rollout of cellular standards in a lead market, which would push volume back toward dedicated short-range hardware and require the forecast to be revised downward.
