Trafficware is excited to announce an update to the background image feature for Bing Maps in Synchro 10. Similar updates will be coming to Synchro 9 soon. This feature allows users to download a background image from Bing Maps without exiting Synchro.
Synchro should alert you that the update is available next time you open the software, or you search for it using the 'Check for Updates' button on the Help tab.
Trafficware is excited to announce the upcoming release of Synchro 10, supporting the latest edition of the Highway Capacity Manual (HCM) 6th Edition methodology for signalized and unsignalized intersections, two-way-stop-control intersections, all-way-stop-control intersections, and roundabouts.
Synchro 10's user interface was updated, introducing a new look and feel with easy-to-use ribbon bar controls.
Applying weighting factors is a great way to customize the optimization routine in Synchro 9. If you haven't tried this new feature yet, this post will get you started. Weighting factors allow you to favor specific movement(s) at some or all of the intersections in the network. There are two choices to apply weighting factors, to specific phase(s) or there is a shortcut to apply a single weighting factor to all of the coordinated phases. Choose which method to use in the Optimize Cycle Lengths window.
“Should I use Synchro, SimTraffic, or both?” We often get this question from users. Today’s post discusses the benefits to help clarify the issue.
The “Choosing an Analysis Method” post from two weeks ago discussed the three macroscopic analysis methods available in Synchro: Percentile Method, HCM 2010, and HCM 2000. In addition to these choices, you can use SimTraffic for analysis.
The intention is to use Synchro and SimTraffic as companion models. Synchro can be used to determine macro level LOS and delays, then use SimTraffic to simulate realworld conditions. Not all projects require use of SimTraffic. Synchro analysis may be sufficient for a high-level planning study, for example.
Not an expert at signal phasing? No problem! Even if you are, using Phase Templates is a great shortcut. The default phase templates are also NEMA compliant. You may remember from last week’s post that the HCM 2010 requires NEMA phasing. Phase Templates are a quick way to set the phasing in preperation for an HCM 2010 analysis.
It is common to assign the main street through movements as phases 2 and 6, so the Phase Templates are setup in this manner. For example, selecting the East-West template will set the eastbound through as phase 2 and the westbound through as phase 6. Here is a diagram of the Synchro default Phase Templates:
A Flashing Yellow Arrow (FYA) can be used to install lead/lag phasing without a left-turn trap. It is also required, in certain situations, by the 2009 Manual on Uniform Traffic Control Devices (MUTCD). So how does it work? And how can it be modeled?
In Synchro, there are 3 methods for reporting signalized intersection delays. This includes:
Each of these methods are macroscopic models, which use equations to determine measures of effectiveness such as delay and queue length. Synchro’s companion model, SimTraffic, is a microscopic simulation model. Microsopic models, like SimTraffic, simulate the movement of individual vehicles. Operational measures of effectiveness are collected on every vehicle and can be summarized in a report. Here I will focus on the 3 macroscopic models listed above and save the comparison between Synchro and SimTraffic for another post.
Don’t waste time setting the Street Name and Link Speed on each individual link along an arterial. Simply enter the Street Nameand Link Speed once, and use the Set Arterial Name and Speed button to propagate the information up and down the entire arterial, including both the selected and opposing direction.
