Tolled trip and Alternative route
Tolled trips are example trips only, and represent trips that incorporate a toll road(s). Alternative trip refers to the alternative route related to the selected Tolled trip as determined by Google Maps Directions API (Alternative trip). Alternative routes may change over time based on Google Maps Directions API.
In some instances, portions of the Tolled trip are not toll roads though a necessary part of the journey if you take the Tolled trip. (e.g. West Gate Freeway between CityLink Western Link and CityLink Southern Link)
Travel times are based on time of departure from the relevant origins of the Tolled trip and the Alternative trip
Start point and end point labels are general in nature, and location names have been used to provide a common reference for users.
Toll costs are based on the trip cost for a single direction trip for an Access Account (including $0.55 vehicle matching fee) for a standard car. Motorbikes, light and heavy commercial vehicles may be charged at a rate that is different to the estimate provided in this tool. Refer to our toll calculator for more detail.
Changing time and day of travel
By default, Trip Compare displays the current predicted travel times for the selected sections. When a user adjusts the time and day of travel, travel times are based on the predicted future travel times provided by Google Maps Directions API.
Vehicle efficiency (fuel used and CO2 emitted)
Vehicle fuel and greenhouse gas estimates are based on formulas extracted from vehicle emissions modelling software COPERT Australia. This method is consistent with what Transurban uses each year in its annual public Sustainability Report to estimate customer vehicle emissions. Comparisons take into account trip distance and travel time information from Google Maps Directions API to calculate the speed for each Tolled route and Alternative route. Results represent a typical petrol passenger car. Actual fuel consumption and greenhouse gas emissions will vary for individual vehicle models and driving behaviour.

Traffic light counts are calculated based on the total number of intersection traffic lights on the relevant Tolled and Alternative trips. Traffic light points are sourced from VicRoads open data “Traffic Signals dataset”.
