TurnCount is the easiest and most intuitive way to count traffic today. Whether you’re a traffic engineer, a transportation planner or just someone wanting to know the number of vehicles and pedestrians entering an intersection, TurnCount is the app for you.

TurnCount works similarly to the traditional turning movement counter board. The user can count traffic with one of two interfaces. One interface, the Hyper Interface, brings an approach to counting traffic that will revolutionize the industry! Vehicles are counted by moving a thumb (or any other finger) in the direction of the vehicle movement. Follow the direction of the arrows or the vehicle path through the intersection. Either gesture works! A quick double tap prior to the finger gesture classifies a truck, a slow swipe counts a bicycle, and pedestrians are counted with a swipe of a finger across the street. Expensive count boards are no longer needed! Visual and audible feedback is provided for each action.

The second interface, the Classic Interface, requires the user to tap a virtual on-screen button for each vehicle movement. This interface is similar to how traditional turning movement counter boards operate. But, the similarities end there! Classify trucks now with a quick double tap of the on-screen button, count bicycles with a long press of an on-screen button, and count pedestrians by swiping a finger across the street being crossed. Visual and audible feedback is provided for each action.

Two user interfaces are available to count traffic. The Hyper and Classic Interfaces are provided as noted above. Count can be collected in either 5 or 15 minute bins. Two user defined vehicle classifications can be toggled on or off.

Screen views are provided for 4-way intersection configurations. Street names are shown in the view to minimize data collection errors.

Traffic count data is provided in five file formats. A JCD file is created to allow direct file import into JAMAR's PetraPro analysis software. A PDF file is created showing a count summary, the peak hour, corresponding peak hour factors, and the peak hour counts shown on an intersection graphic. The iPad interface provides an on-screen preview of the PDF file. A Universal Traffic Data Format (UTDF) file is available for importing vehicle counts into Synchro signal timing software. The time stamp for each vehicle and pedestrian movement is also available in a comma separated value (.CSV) format file for additional analysis in spreadsheet programs. Other traffic studies can be completed when the time stamps are known. Lastly, a .HTML file is created showing count data in tabular format by vehicle type and pedestrians.

Data output is transferred by email OR via the sync cable with the app file sharing feature.

Ratings and Reviews

Great Tool for Data Collection - Turning Movement Counts


I am a practicing / retired traffic engineer with more than 40 years of experience. Why pay $400 to $1,000 for a count board when this is available. Carry your count board with you on your iPhone or iPad.

This is a great app for me. I think it would work great for municipalities and consultants.

I like it and recommend it.

App No Longer Crashing


The developer has addressed the issue with the app crashing on iPads. It now goes back to a four-star rating. Thanks for the quick turnaround.

Reliable but annoying

Ann from Spokane

This app is well worth the price. However, it has some really annoying bugs. The biggest one for me is the lack of being allowed to enter the street names, etc after the count is complete. The next biggest one is the lack of an option to set the company name and for it to stay the same. Having these fields zero out every time is unnecessarily annoying. The third is how easily it crashes while entering the street names, etc. and what's up with the lack of initial capitalization? I don't know any street names that aren't capitalized, same with company names, etc.

These issues aside, the data is collected fully, and has not been lost or corrupted. I have used it a lot and find it just as reliable as the more expensive options.

It is also easy to transfer the data onto a regular computer and it comes in a variety of formats for use. As I said at the beginning, well worth the price.
