Smart Parking in a Historic Urban District: Digitizing Curbside Availability in Portugal

P02-LW sensors embedded in paved bays reuse the district’s existing LoRa network, giving the heritage area real-time parking visibility while minimizing the need for new communications infrastructure.

Project Profile

• Region: Portugal
• Category: City
• Products: P02-LW

Reference Impact

• Zero New Infrastructure — Reuses the existing LoRa network (Infrastructure)
• Est. 25% — Shorter space-search time (Estimated improvement)
• Low-Impact — Installation preserves the historic streetscape (No major construction)

Case Snapshot

Between brick-paved streets and centuries-old façades, a historic district in Portugal needed curbside parking to improve without disturbing its protected streetscape. Narrow roads and protected paving ruled out major construction or visible new equipment. The district installed P02-LW LoRaWAN sensors beneath brick-paved bays, with signals riding the area's existing LoRa network instead of a new one — cutting the circling drivers used to do while searching for an open space in the narrow streets.

Problem

No Open Bay in Sight, So Traffic Keeps Circling

Parking improvements in historic districts run into building preservation rules, paving restrictions, and tight construction windows. Laying new cable or building a dedicated network to capture bay status raises cost and timeline, and the construction work itself risks damaging the very streetscape the project is meant to protect.

Without real-time bay data, drivers rely on guesswork and close-range searching. That circulation adds unnecessary traffic to already narrow streets and stretches out the time it takes to park — and during peak tourist hours, the backup at a lane mouth can turn into friction between pedestrians and circling cars right in the street.

Solution

Sensors Go Under the Bays, Signals Ride the Existing Network

P02-LW LoRaWAN parking sensors were installed beneath brick-paved curbside bays to detect occupancy, transmitting status data over the area's existing local LoRa network rather than a newly built one.

That choice keeps the streetscape impact to a minimum — the deciding factor for a heritage district willing to accept smart parking. Scattered curbside bays now feed a continuous stream of live data to platforms and parking guidance, while the brick paving and building façades stay essentially untouched.

Value

Bays Become Visible, the Streetscape Stays Intact

The brick paving looks untouched, but underneath it, every bay now reports its status continuously, feeding parking guidance, space-search tools, and ongoing management analysis. Drivers spend less time circling and confirming a space by sight.

The next lane worth adding to the network just needs a sensor under the brick joints — the signal picks up the existing LoRa network on its own. Smart parking in a historic core doesn't require heavy construction — it requires fitting sensing and connectivity to the constraints already on site.

Next Step

Coverage should be verified rather than assumed. A representative street segment can be used first to assess whether the existing LoRa network is suitable for bay-level reporting.
