• Native 64 bit applications
  
• Multiple-Core/Thread SSAM Conflict Analysis
  
• Parallel processing Surface/Freeway vehicles
  
• Distributed Architecture Through WCF
  
• Multiple run could be deployed on different CPU simultaneously​

• Components based, related to real world, such as vehicles, detectors, traffic control systems, etc.
  
• Both data and function access for commonly used components
  
• Multiple network protocol support (HTTP, TCP/IP, SOAP)
  
• Cross platform and mobile interface (through HTTP/SOAP)
  
• Almost any programming language that supports WCF: C#, C++, VB, html, Python, etc.
  
• API functions that allow the executive system to access and modify simulation data, such as vehicle desired speed, turn code, destination, etc., and to access and modify fixed-time signal parameters, such as duration of green time or current interval
  
• API Examples showing how to interface with user developed traffic signal control algorithms, lane changing/car following algorithms through ETAPI.​
