Working in the Traffic / ITS industry for over a decade now, I have worked with various hardware devices, software, new technologies, and traffic modeling systems. If you are in the transportation industry or even a member of the traveling public, you've probably thought to yourself numerous times that there has to be a simpler way of coordinating traffic. I said that to myself over and over, then Dr. Tian introduced me to WaySync. WaySync is so intuitive, so efficient, and so simple, yet a powerhouse tool that can coordinate intersections at the press of a few buttons. The software will model, optimize, make suggestions, generate reports, and even take video while you're driving to show how the drive aligned with your time-space diagram in real time. If you're looking for a tool that will make coordinating traffic easier, validate current traffic conditions, or verify a retiming project was successful, this is all you need. If you're a technician, operator, engineer or planner, new to the industry or have been doing it for years, this software can cut learning curves, make any traffic project easier and professionally presented to any audience. My personal opinion is that WaySync is the best thing on the market and my personal favorite traffic software to use. I applaud the WaySync team for designing an application that truly does it all.

As a traffic signal engineer with three years of experience, I have found WaySync to be an invaluable tool for modern traffic operations. Its intuitive interface allows for quick learning and efficient day-to-day use, while still proving to be powerful enough to help users visualize complex coordination and implement timing adjustments. WaySync has streamlined processes that previously required extensive time and effort. One of the most impactful features is the WaySync-M mobile application. The app provides a real-time status display of each controller, along with a dynamic view of the Time-Space Diagram. Its ability to overlay live video during corridor drives on top of the Time-Space Diagram has proven especially valuable, allowing staff to visualize and validate both existing and proposed signal timing changes directly in the field. By leveraging the full WaySync Suite, both desktop and mobile, we can effectively document and showcase before-and-after conditions of signal retiming, facilitating communication of signal timing improvements to City leadership as well as to the public. For these reasons, WaySync has demonstrated itself to be a reliable and innovative solution that facilitates our enhancement of operational performance and strengthens our ability to deliver safe and efficient mobility. The City of Austin looks forward to continuing its use of the program and its role in supporting our transportation objectives.

In my 40 plus years with municipalities, and different State DOT’s, the frustrations of signal timing have never been easy. A green for some is still a red for others. You can never make everyone happy. All you can do is reduce delays and try to increase safety. We have come a long way baby! Forty years ago, traffic signal timing consisted of inserting keys in a dial to determine your green, yellow and red timing. The dial was a simple 90 seconds, depending on the gear you had installed. Then along came electronics and the signal timing world changed forever. Today we have coordination timing, logic processors, variable initial timing, delayed calls, advance ped start times, and entire host options to assist with moving cars, bikes and pedestrians safely through an intersection and down a corridor. Synchro has been a great tool to assist Traffic Engineers to determine how to take advantage of the available options in the controllers and insert traffic volumes to ensure that all directions are serviced adequately. It has been a great starting point to develop traffic signal timing based on demand. Develop your timing plans, deploy them and then drive the corridor to see the results. Come back to the office, adjust and drive it again. After two or three iterations of this, you might have a coordination plan that works. All while you review the time/space diagram to determine what you missed. Now we use WaySync to eliminate the guess work. We can import the Synchro data directly into the program, do the fine adjustments on the computer (WaySync D), then drive the corridor, all while recording your virtual position in the green band, and record video of the run to determine what was different than expected during the run, like pre-emption, side friction and other delays that may not have been evident in your modelling of the corridor (WaySync M). If you haven’t tried WaySync, it is worth your time and effort to realize the benefits and eliminate the guessing. Read the other testimonials and decide for yourself. I can’t wait to see what AI will do with WaySync. Don’t be afraid to use technology that works.

As a user of this incredible tool (WaySync), I have experienced firsthand its remarkable features and the positive impact it has had on my work efficiency. I’ve used this software on timing projects for multiple Cities in California, where I was able to provide final optimization and fine-tuned plans quicker with program features, including virtual trajectories, early return to green values, real-time clocks, and the ability to record and import GPS/Video paired travel runs. The quality of this data and information is second to none with regard to signal timing software on the market and my ability to perform signal synchronization projects.

Over the last few years, I’ve had the humble opportunity to learn and utilize the WaySync (formerly TranSync) signal timing software. As both an agency and consultant signal timing engineer, the benefits of combining WaySync along with Synchro into my workflow have been far reaching. WaySync has a plethora of useful features in supporting the signal timing engineer to produce the best possible signal timing plans. The most useful features include a streamlined work flow, ability to easily optimize a combination of parameters, ability to model/manage an entire signal network in a single file, ability to optimize crossing corridors with side by side Time-Space Diagrams, and a mobile companion application that is used when performing field assessments/travel runs. Unlike other software used to perform travel runs, WaySync’s iOS application shows a real time status screen of each controller and a dynamic view of your Time-Space Diagram. It also overlays video, as you drive your corridor, on top of your Time-Space Diagram. There’s no more guessing what the signal should be doing and where on your Time-Space Diagram you may or may not be at a given time and location along your corridor. I strongly encourage other signal timing engineers across the country to check out WaySync and try it on your next signal timing project. Let’s work together to continue bridging the gap on signal timing and controller programming knowledge. We owe it to our communities of roadway users who depend on our distinguished skillsets to keep all modes of traffic safety and efficiently moving.

I have had the pleasure of working in the traffic industry for nearly 30 years. I have successfully timed nearly 3000 traffic signals across Canada, the United States, and Caribbean, and have programmed, or worked with nearly every traffic controller, traffic system and traffic software available. In my early years, I worked with a Time-Space Diagram software that we developed here in Ontario, Canada that provided some of the basic functionality of WaySync, but now, years later Dr. Tian and the University of Reno (CATER) have taken the Time-Space Diagram from what I envisioned it could be, to what it should be. Many applications that used to take hours are now done in minutes. Import/Export functionality from Synchro to WaySync dramatically reduces data transfer time and errors. WaySync is the traffic signal application every engineer should have at their fingertips. It’s easy to use data screens, offset manipulation, and scenario options, allow the user to make efficient, calculated adjustments to timing plans – and the graphic screens are easy to understand with changeable window and graph colors for us Colorblind people. The WaySync-M mobile application allows the user to conduct travel time studies or project real time trajectories for instantaneous signal timing adjustments. WaySync-M can also be used as a hands-free application to record both GPS data tracking and real-time video. My favorite features of the WaySync program include the Early Return feature within the Time-Space Diagram, which allows for estimations of returning unused side-street split time back to main-street. The single greatest feature of WaySync though, is that it’s always evolving. For traffic engineers – no more ‘I wish’ and a lot more ‘I can’.

I have always sought a reliable tool that allowed me to observe coordinated signal operation in the field and compare the operation to the intended timing. I have often seen sync phases improperly defined, phases rotated, or directions reversed upon implementation. In places like Orange County, CA, a corridor may go through several jurisdictions, each can have a different central system and controllers manufactured by various vendors. It has always been a challenge to maintain a consistent clock and ensure the correct offset reference point. It can be very difficult to diagnose the problem if the coordinated phases are actuated and gapping out at the wrong time. In the earlier days prior to the smartphone, I had an intern write an app to create a cycle timer sync’d to midnight or a sync input hour. I used it with a time-space diagram to verify offsets in the field. WaySync employed the exact same concept and is a nicely designed app to achieve much more than a simple timer. WaySync is the best tool I have seen for this purpose. It also can show a test car trajectory and sync’d video on the time-space diagram, so I can playback the recordings and tell from the office whether the signals are operating as intended. This tool earns its value in ensuring that the signal system is operating as intended in a much easier way, for both experienced users or new engineers to this field.

I have been performing traffic signal timing work for 25 years now using Synchro (and SimTraffic) and have recently acquired a tool that is going to make my life much easier. That is especially true for evaluation and fine tuning of new signal timing plans in the field. Where Synchro breaks down for me is in the field testing. You can use printed time space diagrams from Synchro to try and field test and fine-tune operation, but the real-time clock and display of anticipated signal phases offered in the mobile version of WaySync is a real game changer. The WaySync software allows you to see where you are at on the corridor and within the time space diagram using the GPS tracking feature. The software also provides the green/yellow/red interval times remaining for all active signal phases giving the engineer a good understanding of how well the plan is running. This also allows the engineer to easily pinpoint problems in the programming of the plan or to identify opportunities for improvement, even if your network is partitioned and using multiple cycle lengths. Use of the iPhone/iPad camera to add a video, synced with the time space diagram and vehicle trajectories makes WaySync a perfect tool for field evaluation and fine tuning. You can even use the microphone to record observations of your travel time run. The office (desktop) version of the software has lot of interesting features as well that allow me to test certain elements of timing plans in a way that is a tricky to do in Synchro. The built-in performance statistics generated by the actual travel runs will allow me to perform before and after studies, and also document key performance measures for year over year comparisons. After using the WaySync software for just a short time, I know that I will be using it for all my timing projects in the future to save time and ensure proper operation.

I learned to design, implement, and fine-tune signal timing plans as a student of Dr. Tian’s using WaySync. Several features of WaySync accelerated my learning of signal timing. The time-space diagram is very useful by being easy to read, including all the necessary coordination information, and easy editable to see what impacts timing changes might have, which are all important for understanding signal coordination. While driving along a corridor, the time-space diagram moves in real time, showing your position in relation to the bandwidth and the state of each signal. Since WaySync places a higher emphasis on real-world implementation, as students, we spent a lot of time in the field observing traffic, doing travel runs, and fine-tuning. All this practical experience using WaySync as a student has given me the skillset and judgement needed to jump right in as a young professional to help cities around the San Francisco Bay Area with their signal timing. WaySync allows our company to verify signal operations in the field and make better informed decisions to improve what the end road users experience. With the mobile app, we can quickly check if each signal is running accurately by comparing what WaySync shows is the correct operation (based on the programed coordination parameters) with the current state of the signal. If the signal timing does not match WaySync, we know there needs to be some troubleshooting. WaySync also allows us to save time with before and after studies by automatically calculating and comparing important measures of effectiveness based on travel runs collected in the mobile app. WaySync gives us confidence in our timing, which builds trust with our clients.
