Welcome:

ATTAP is jointly initiated by the Office of Traffic and Safety at the Maryland State Highway Administration and the Traffic Safety and Operations Laboratory at the University of Maryland - College Park

Goals and Objectives:

  • Work in partnership with the University of Maryland;
  • Develop state-of-art traffic engineering analysis tools and technologies;
  • Provide traffic engineering technical expertise to University of Maryland students/staff;
  • Develop and maintain an internet based traffic engineering innovation and information resource site; and
  • Provide on site support in traffic engineering analysis and applied operations to the Traffic Development and Support Division/Office of Traffic and Safety - Maryland State Highway Administration.

Recent Activities  (More)

 

 
1.   Dr. Gang-Len Chang's Traffic Safety and Operations Center has recently been awarded a project of $542,778 over a period of 18 months to design and operate an Advanced Incident Response System for the Eastern Shore region. This project, sponsored jointly by FHWA/MDSHA, is an extension of Dr. Chang's Intelligent Transportation System research over the past 10 years on Ocean City and Eastern Shore. The focus of this phase is to provide the estimated traffic delay and duration due to a detected incident, including the predicted travel time during incident clearance operations, the criteria and models to guide any necessary detour operation, and the resulting time-varying traffic impact to both motorists and the entire region. The results of this research will be integrated with Dr. Chang's other $1.5 million on-going projects (http://www.oceancity.umd.edu) to develop a test bed for advanced traffic management systems for Maryland State Highway Administration.
2.   MDQI (Maryland Quality Initiative) presentation on "National Prespective on Diverging Diamond Interchange" is available. Click here for more information
3.   ATTAP's visual simulations on UAID are referenced on TEDx Talks event about unconventional Intersections. For more information, please click the following link "Can we live with traffic?" by John Sangster at TEDx Virginia Tech
4.   UMDTEST (Universal Modular Distributed Traffic Extendable Simulation Toolkit) , a web-based modular traffic simulation platform has been developed by ATTAP. Currently, it can employ either of two simulation engines: (1) a vehicular evacuation simulation and optimization engine based on research by Xin Zhang and (2) a freeway macro-particle simulation model (MPSM)
5.   ESSIM (Eastern Shore Simulator), a web-based evacuation simulator for Ocean City and the Eastern Shore region has been developed using the UMDTEST framework. The demo is currently available at the oceancity.umd.edu website
6.   6 papers from ATTAP members have been accepted for 92th TRB annual meeting.
7.   A Success research accomplishment for the Applied Technology and Traffic Analysis Program (ATTAP) led by Professor Chang
Mark L. Franz will be presenting the dilemma zone research at the 6th Regional Traffic Signal Forum & ITS MD Annual Meeting.

8.   Eastern Shore regional traffic monitoring and management system update presentation is available.
9.   Xin Zhang finished his Ph.D. thesis defense. The thesis title is "Development of a Mixed-flow Optimization System for Emergency Evacuation Networks".
10.   The Dynamic Dilemma Zone Protection has been successfully implemented and demonstrated its effectiveness in preventing accidents.
11.   5 papers from ATTAP members have been accpeted for 91th TRB annual meeting.
