If you manage a commercial parking lot in Edmonton or Calgary, you've probably considered installing speed control measures. The two most common options — speed bumps and speed humps — are often confused, but they serve fundamentally different purposes. Installing the wrong one can create vehicle damage claims, driver complaints, or worse, fail to protect pedestrians.
This guide breaks down exactly when to use each, what they cost, and which Alberta properties benefit most from each type.
What's the Difference?
The terms "speed bump" and "speed hump" are often used interchangeably, but they describe two distinct traffic calming profiles with very different effects on vehicles.
Speed Bumps
Key Facts
Height: — 3–6 inches (75–150 mm)
Length: — 12–36 inches travel length (short and abrupt)
Target speed: — 5–15 km/h
Impact: — Aggressive — forces near-complete stops
Best for: — Parking lots, parkades, warehouse yards, private roads
Speed bumps are the aggressive option. Their short travel length creates an abrupt vertical deflection that forces drivers to slow to near-walking speed. They're designed for environments where pedestrians and vehicles share tight spaces and speeds must be kept to an absolute minimum.
Speed Humps
By the Numbers
Height: — 3–4 inches (75–100 mm)
Length: — 12–22 feet travel length (gradual rise and fall)
Target speed: — 25–35 km/h
Impact: — Gentle — slows traffic without forcing stops
Best for: — Through-roads, residential streets, drive aisles with regular traffic flow
Speed humps are the gentle option. Their extended travel length creates a gradual rise that slows vehicles comfortably to moderate speeds. They're designed for environments where traffic needs to flow but at controlled speeds.
Pro Tip
If you need drivers to slow down, use humps. If you need drivers to nearly stop, use bumps. The distinction matters — and choosing wrong creates either liability or frustration.

When to Use Speed Bumps
Speed bumps are the right choice when your priority is maximum pedestrian protection in low-speed environments:
At a Glance
Retail parking lots — near building entrances, crosswalks, and cart corrals where shoppers walk
Parkade ramps and turns — where sightlines are limited and pedestrians share narrow lanes
[Warehouse yards](/services/speed-bump-installation/parking-lot) — near loading docks where workers are on foot alongside delivery trucks
Drive-through lanes — controlling speeds near pick-up windows where workers lean out
School and [daycare](/services/bollard-installation/daycares) drop-off zones — where children are present and unpredictable
Materials and Installation
For Edmonton and Calgary properties, the two most common speed bump materials are:
- 1Rubber speed bumps — Modular bolt-down units that install in hours. Easy to relocate if your lot layout changes. Last 5–10 years depending on traffic volume. Cost: $300–$800 per bump.
- 2Asphalt speed bumps — Permanent hot-mix construction built directly onto the lot surface. More durable but requires line painting for visibility. Cost: $500–$1,200 per bump.
Both options are available through our speed bump installation service across Edmonton and Calgary.
When to Use Speed Humps
Speed humps are the right choice when your priority is traffic calming on through-roads without disrupting flow:
Quick Stats
Long drive aisles — in shopping centres where vehicles need to maintain moderate flow
[Parking lot](/services/speed-bump-installation/parking-lot) access roads — connecting lot sections where 25–30 km/h is appropriate
Multi-tenant property roads — private roads serving multiple businesses
Residential-adjacent commercial properties — where neighbourhood traffic cuts through your lot
The Emergency Vehicle Consideration
One critical difference: speed humps allow emergency vehicles to pass at reasonable speed, while speed bumps force fire trucks, ambulances, and police vehicles to slow dramatically. If your property's access road is an emergency route, speed humps are almost always the better choice.
For properties with fire lane requirements, our fire lane line painting service ensures your speed calming measures comply with municipal access codes.
Cost Comparison for Alberta Properties
| Feature | Speed Bumps | Speed Humps |
|---|---|---|
| Material cost | $300–$1,200 each | $1,500–$3,000 each |
| Installation time | 1–3 hours per bump | Half day per hump |
| Lifespan | 5–15 years | 10–20 years |
| Maintenance | Re-bolting, replacement | Re-paving, repainting |
| Best lot size | Small to medium | Medium to large |
Common Mistakes Property Managers Make
- 1Installing Speed Bumps on Through-Roads — Speed bumps on roads with regular traffic create vehicle damage complaints and angry drivers. If vehicles need to travel at 25+ km/h, use humps.
- 2Inadequate Signage and Marking — Unmarked speed bumps are a liability trap. Every speed bump and hump needs high-visibility line painting — yellow chevron markings, advance warning signage, and reflective paint for nighttime visibility.
- 3Wrong Spacing — Speed bumps too far apart let drivers accelerate between them. Too close and traffic backs up. Optimal spacing: 50–100 feet for bumps, 200–400 feet for humps.
- 4Ignoring Drainage — Speed bumps and humps placed across drainage paths create standing water and ice hazards — especially dangerous in Alberta's freeze-thaw climate. Your installer should account for surface water flow.
What About Speed Tables?
Speed tables are a hybrid option — flat-topped humps that double as raised crosswalk platforms. They're increasingly popular in Canadian parking lots because they:
- Slow traffic to 20–30 km/h
- Create a visible, elevated pedestrian crossing
- Allow smoother vehicle passage than bumps
- Meet accessibility requirements for wheelchair and stroller access
If you're considering speed tables, contact us for a site consultation — they work best when combined with proper crosswalk markings and bollard protection at crossing endpoints.
How to Decide: A Quick Framework
Ask yourself these three questions:
- 1What speed do you need? Under 15 km/h → bumps. 25–35 km/h → humps.
- 2Is it a through-road? Yes → humps. Dead-end or parking area → bumps.
- 3Do emergency vehicles use it? Yes → humps. No → either option works.
