GeoKontrol: GPS Zone-Based Speed Limiting for Fleets

Traditional speed limiters set a single maximum speed for the vehicle — typically 56mph for HGVs or 62mph for buses. This is effective for motorway and open-road speed management, but it does nothing to control vehicle speed in the locations where most serious fleet-related injuries actually occur: depots, yards, customer sites, and residential areas.

GeoKontrol solves this problem by combining GPS positioning with speed limiter technology to automatically adjust the vehicle’s maximum speed based on its location. It is the most advanced speed management technology available for commercial fleets, and it is unique to AutoKontrol.

The Depot Safety Problem

HSE data shows that approximately 50 people are killed each year in workplace transport incidents in the UK, with many more seriously injured. A significant proportion of these incidents occur in depots, distribution centres, warehouses, and construction sites — controlled environments where vehicles interact with pedestrians, forklift trucks, and other mobile plant.

The common factor in many of these incidents is vehicle speed. A vehicle travelling at even 15 to 20mph can cause fatal injuries in a collision with a pedestrian. In confined spaces with limited visibility, the safe speed may be as low as 5mph.

Traditional speed limiters cannot address this risk because they are set to a fixed maximum speed designed for open-road use. A speed limiter set to 56mph does nothing to protect a pedestrian in a depot yard. Warning signs, painted lines, and management instructions help, but they rely on driver compliance. GeoKontrol enforces the speed limit automatically.

How GeoKontrol Works

GeoKontrol is a feature of the TrackSpeed combined speed limiter and GPS tracking system. It uses the vehicle’s GPS position, determined by the ScorpionTrack Fleet tracking component, to identify when the vehicle enters or leaves a predefined speed zone.

Zone Definition

Fleet managers define speed zones using the ScorpionTrack Fleet web portal. A zone is simply an area drawn on a map with an associated speed limit. Zones can be any shape — circles, rectangles, or custom polygons — and any size, from a small yard area to an entire town.

Each zone has a name, a maximum speed, and optionally a time schedule. For example, a school zone might have a 20mph limit that only applies during term-time school hours, reverting to the default maximum at other times.

There is no limit to the number of zones that can be created. National fleet operators typically define zones for all of their depots, customer sites, and any location-specific speed requirements.

Automatic Speed Adjustment

When the vehicle crosses the boundary of a speed zone, GeoKontrol automatically adjusts the speed limiter setting. The transition is smooth and progressive — the vehicle decelerates naturally as the driver lifts off the accelerator, rather than braking suddenly.

When the vehicle leaves the zone, the speed limit automatically reverts to the next applicable zone, or to the vehicle’s default maximum speed if no zone applies.

The driver is informed of the speed limit change through a dashboard-mounted display or indicator. The system is transparent — the driver knows what the speed limit is and why it has changed.

Zone Nesting and Priority

Zones can overlap, or nest inside each other. GeoKontrol always applies the lowest applicable speed limit. For example, an operator might define a 20mph zone for an industrial estate, with a 5mph zone for the specific loading bay area within it. When the vehicle is in the loading bay area, the 5mph limit applies. When it moves into the broader industrial estate but outside the loading bay zone, the 20mph limit applies. When it leaves the industrial estate entirely, the default maximum applies.

This nesting approach allows fleet managers to create layered speed management that mirrors the real-world environment.

Practical Applications

Distribution Centre Operations

A typical distribution centre GeoKontrol setup might include:

Zone	Speed Limit	Area
Approach road	30mph	Road leading to site entrance
Site entrance / gatehouse	10mph	Entrance area with security barrier
Yard / circulation area	15mph	Main yard between buildings
Loading bay approach	5mph	Area directly in front of loading docks
Fuel island	5mph	Refuelling area

This setup ensures that vehicles arriving at the distribution centre progressively reduce speed as they move from the public road network into the site, reaching walking pace at the loading bays where pedestrians are most likely to be present.

Construction Sites

Construction sites present particular speed management challenges. The site layout changes as the project progresses, access roads may be temporary, and there are large numbers of pedestrians, plant vehicles, and temporary structures.

GeoKontrol zones can be created and modified instantly through the web portal, allowing the site manager to adjust speed zones as the site layout evolves. No physical infrastructure (speed bumps, barriers) is needed — the speed management is entirely electronic and GPS-based.

School and Residential Zones

Bus operators and local authority fleets use GeoKontrol to enforce reduced speeds near schools. Time-scheduled zones automatically activate during school drop-off and pick-up times, ensuring buses approach schools at safe speeds without requiring driver intervention.

Delivery fleets serving residential areas can set reduced speed limits for housing estates and narrow streets, reducing noise, emissions, and risk.

Customer-Mandated Speed Limits

Many customers — particularly in manufacturing, pharmaceuticals, food processing, and utilities — require delivery vehicles to observe strict on-site speed limits. GeoKontrol allows the fleet operator to programme these customer-specific speed limits once, after which they apply automatically every time a vehicle visits that site.

This provides documented, enforceable compliance with customer speed requirements, which can be a differentiating factor when tendering for contracts.

Benefits of Zone-Based Speed Limiting

Workplace safety: Directly addresses the leading cause of depot and site transport injuries.

Compliance: Provides evidence of active speed management for HSE inspections, customer audits, and insurance assessments.

Reduced site damage: Lower speeds in confined areas reduce the frequency and severity of damage to vehicles, buildings, loading equipment, and stock.

Noise reduction: Lower speeds in residential and urban areas reduce engine and tyre noise — particularly important for early-morning and late-night delivery operations.

Environmental benefit: Lower speeds in urban areas reduce emissions in the locations where air quality matters most.

Driver acceptance: Drivers generally welcome GeoKontrol because it removes ambiguity about what speed is expected at different locations. There is no need to remember site-specific speed limits — the system handles it automatically.

Reporting and Audit

Every GeoKontrol speed zone event is logged by the ScorpionTrack Fleet platform. Fleet managers can access detailed reports showing when vehicles entered and exited each zone, maximum speeds recorded within each zone, any instances where a driver attempted to exceed the zone speed limit, and historical compliance trends.

This data is valuable for health and safety audits, customer compliance reporting, and insurance claims defence.

Getting Started with GeoKontrol

GeoKontrol is available exclusively as part of the TrackSpeed combined speed limiter and GPS tracking system. It is not available as a standalone product, because it requires the integration of speed limiter hardware and GPS tracking that only TrackSpeed provides.
