Choosing an Analysis Method

In Synchro, there are 3 methods for reporting signalized intersection delays. This includes:

• Synchro Control Delay (Percentile Method)
• HCM 2000
• HCM 2010 (new in Version 8)

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.
