To view tabulated traffic analysis results

The Analysis tab in the Traffic Analyst Panel shows results calculated when the simulation preview runs. Full analysis results are generated when a simulation runs on the cloud, and these generated results files can be accessed using the asset card for the Traffic Study Area.

After completing a simulation run,

1. Select the Traffic Study Area.
2. Choose Traffic Analyst Panel from the Traffic Study Area right-click menu.

   Wait for the panel to load and display.

3. Click the Analysis tab to display the tabulated results, starting with the summary results.
   Click the tabs at the bottom of the panel to see other tabulated results:

   

Analysis - Summary

Completed Trip Drive Distance	The sum of all incremental movements of distance by all vehicles. This length may not be exactly the same as the length of all lanes and streams travelled, as a vehicle may not always follow the centre line of a lane or stream.
Completed Trip Drive Time	The sum of all time increments from the time at which the vehicle was created in the model to the time of arrival. The time of creation may be after the trip start time, due to congestion at the origin. The additional time will be recorded in the unreleased.
Incomplete Drive Distance/Time	Reported for all trips that have not yet arrived at the destination .
Unreleased Time	The sum of all time increments for vehicles which could not be released at the trip start time because of congestion at origin.
Extra Distance / Time	If extra people have been defined for a vehicle type, this is the sum of the distance and time for those extra people. This sum can be used to get a value for PHT and PKT for the driving part of a trip without defining person-trips.

Analysis - Departures - Unreleased - Arrivals

These tabs show counts of vehicles arranged in a grid according to origin & destination, like demands.

Departures	Vehicles that have successfully departed from the origin
Unreleased	Vehicles that were due to depart, but are blocked by congestion
Arrivals	Vehicles that have successfully arrived at the destination

Analysis - Intersections

LOS	The Level of Service: a letter from A to F, with A corresponding to low average delay
Delay	A time in seconds representing the average delay for vehicles in all lanes on an approach. The Level of Service (LOS) is calculated from this delay. This value is the sum of the approach delay and the acceleration delay. Approach delay is the difference between the time that a vehicle takes to traverse the entire approach to the intersection and the free-flow time. Acceleration delay is the time needed by the vehicle to accelerate back up to the exit free-flow speed after it has crossed the stop line. This value is approximated by assuming that the vehicle accelerates at a constant rate (its maximum acceleration rate) from its current speed up to the exit free-flow speed.
Maximum Queue	The maximum queue length experienced by queuing vehicles, where a queuing vehicle is one travelling at less than the queue threshold speed. The queue threshold speed is defined as 0.25 x the route speed on the first link of the approach. The queue delay is a rolling average value, updated every second.

Analysis - Roads

Vehicles	Count of vehicles that have completed the link
People	Count of all people in vehicles counted above
Mean Time	Mean travel time for the link
Mean Flow	Mean flow calculated from count of vehicles in measurement period
Mean Speed	Mean speed calculated from travel time and link length
Mean Density	Mean density, calculated from mean entry interval time over mean travel time
Density	Instantaneous density, calculated from number of vehicles on all lanes of road divided by length of road

Analysis - Loops

Occupancy Time	Instantaneous occupancy time. Zero if unoccupied
Non-occupancy Time	Instantaneous gap time. Zero if occupied
Occupancy Ratio	Ratio of total occupancy time to total time
Non-occupancy Ratio	Ratio of total non-occupancy time to total time
Flow	Flow calculated from count of vehicles between first and last event
Vehicles	Count of vehicles passing loop
People	Count of people in vehicles passing loop
Headway	The headway in seconds) between the last two vehicles, measured head to head
Gap	The head-to-tail gap (in seconds) between the last two vehicles (headway minus vehicle length/speed)
Vehicle Length	Mean vehicle length
Density	Density calculated form mean vehicle length
Gap Speed	Speed calculated from occupancy and mean vehicle length
Gun Speed	Mean of instantaneous speeds of vehicles at loop
