Short answer: congestion adds driver time, fuel use and uncertainty to a delivery day. Sofia's city-wide data shows the pressure on the road network. Your route log shows the cost for your operation.
Key takeaways
- TomTom reports 113 rush-hour hours lost in Sofia in 2025.
- The figure describes city traffic across the year.
- A useful route log separates road delay, loading, waiting and stop-order problems.
- Your labour and fuel rates turn recorded delay into a business cost.
What the Sofia traffic figure measures
TomTom’s 2025 Traffic Index reports an average congestion level of 47% for Sofia and 113 hours lost during rush hour over the year. It also reports that a 10 km trip took an average of 27 minutes and 2 seconds across all days and times.
TomTom builds these figures from anonymised trip data across the road network. The result describes general traffic conditions. Each delivery operation still needs its own route records to calculate time and money.
Turn delay into an operational cost
Record planned and actual start time, planned and actual finish time, planned distance, actual distance when available, completed stops and failed stops. Add a short reason for delays such as congestion, loading, parking or waiting for a customer.
A transparent formula
Estimated traffic cost = added driver hours × hourly employment cost + extra fuel used × fuel price + documented late-delivery costs.
Use payroll, fuel invoices and customer agreements for the rates. Industry averages provide context. Your accounts provide the budget figure.
Plan for the traffic you can see
First remove avoidable route problems: backtracking, repeated crossings of the same corridor, and an uneven split between couriers. Then compare the plan with known busy periods and fixed delivery commitments.
MileCut’s Team plan arranges and groups stops using the road network. Control can also check planned routes against current traffic for the selected departure time and show when the check was made. The check supports planning before departure. MileCut does not track vehicles during the shift.
Run a fair route comparison
Compare similar days over several weeks. Keep the service area, number of stops, and vehicle type as consistent as possible. Look at distance per completed stop and minutes per completed stop. If a traffic incident or road closure affected only one day, mark it rather than treating it as normal performance.
A useful plan reduces avoidable crossings and exposes likely delay before the vehicles leave. Congestion remains part of the day, so keep measuring actual results after departure.
Review the plan comparison to see which traffic features are included, or use a 7-day Team trial to test the base planning workflow.
