AI-Powered Smart Scheduling for Mobile Vehicle Inspections

Pink Slips NSW

AI scheduling that clusters appointments geographically, cutting daily travel time by 40%.

Guy runs a mobile vehicle inspection service across Greater Sydney. The old booking system had him zigzagging across the city, spending 3+ hours just driving between jobs. We built an AI scheduling system that clusters appointments geographically and validates travel times in real-time.

40% Less Driving, Same Number of Jobs

Smart scheduling that actually works

Guy runs a mobile vehicle inspection service across Greater Sydney. Before this system, he was zigzagging across the city, spending 3+ hours just driving between jobs. Now the AI clusters appointments geographically and validates travel times in real-time.

The Result

The Problem: Random Booking Chaos

The old booking process was reactive. Customer calls, staff checks the calendar, guesses at a time. No consideration of where the technician will be before or after. The result? Days that looked like this:

The Problem We Solved

Before vs After

PROBLEM

Manual booking with no travel consideration. Technician zigzagged across Sydney, 3+ hours driving between jobs.

SOLUTION

AI validates travel times in real-time. Both legs must be under 35 mins or the slot is rejected. Geographic clustering automatic.

The Solution: AI That Thinks About Geography

We built a scheduling engine that checks every potential time slot against real travel times. Before accepting a booking, it calculates: How long to get there from the previous job? How long to get to the next job? Both must be under 35 minutes or the slot gets rejected.

1

Load Context

Pull all existing calendar events for the next 14 days, plus the customer's address and availability preferences.

2

Check Each Slot

For every potential time: skip weekends, skip full days (8+ jobs), skip conflicts, then calculate travel times via Google Maps API.

3

Validate or Fallback

If travel is under 35 mins both ways, book it. If no slot fits, find the closest existing job and schedule nearby for clustering.

How The System Works

Smart Scheduling Logic

  • 1

    Load calendar + customer preferences

  • 2

    Calculate travel FROM previous job

  • 3

    Calculate travel TO next job

  • 4

    Both under 35 mins? Accept slot

  • 5

    No match? Cluster near closest job

4Both ≤ 35 mins? → Accept slot
5No valid slot? → Find closest job, cluster nearby

Schedule Transformation

Daily Schedule

Before

Random bookings, 3+ hours driving between jobs, zigzag routes

After

Geographic clusters, 10-15 min between jobs, regional routes

Real Test: Natasha from Woronora

Woronora is isolated in the Sutherland Shire. Most of the week's jobs were in the northwest—over an hour away. The old system would have just picked the first available slot. Here's what the smart system did instead:

Customer Location

Woronora, NSW (Sutherland Shire)

The Challenge

  • From Wahroonga (Tue): 1 hr 4 mins
  • From North Ryde (Tue): 45 mins

System Decision

Found Beata at 10 AM Thursday in Gymea (also Sutherland Shire)

Travel Woronora → Gymea: 10 minutes ✓

Generated Response:

"Hi Natasha, we can schedule you in next at Thu 4th at 9:00 AM"

Real Test Case

Natasha from Woronora

Week 1

1hr+ travel rejected

Week 2

Found Sutherland cluster

Week 4

10 min travel confirmed

The Insight

"

The system doesn't just find available slots - it finds EFFICIENT slots. Every booking is validated against real travel times before it's offered.
