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.   The Dynamic Dilemma Zone Protection has been successfully implemented and demonstrated its effectiveness in preventing accidents.
2.   5 papers from ATTAP members have been accpeted for 91th TRB annual meeting.
3.   ATTAP made a presentation on Maryland Unconventional Intersection Design (MUID) in MDQI (Maryland Quality Initiative) meeting on Feb 2nd 2012 at Baltimore. MDQI is a cooperative effort by Maryland's transportation industry dedicated to the continuous quality improvement in the planning, design, construction, and maintenance of Maryland's transportation system.

4.  A workshop for the Maryland Capacity Analysis Program (MDCAP) and the Maryland Unconventional Intersection Design program (MUID) was hosted by ATTAP on November 17th 2011 at University of Maryland, with over 20 officials from MD SHA in attendance.

5.   3 new sensors have been deployed in the Eastern Shore Region.

6.   2 new papers have been accepted for the 18th Intelligent Transportation System (ITS) World Congress by ATTAP members.

7.   Computer simulation based Baltimore Evacuation System, developed by ATTAP members, has been applied to evaluate the traffic impact study during Grand Prix (September 2-4 2011) in Baltimore City for traffic management plan.

8.  Traffic volume data (inbound/outbound) in Ocean City, Maryland during the hurricane Irene evacuation is now available.

9.   A new report on developing evaluation models for CFI and DDI designs has been completed and place on the ATTAP website.
10.   The project, "Integration of VSL with travel time information for non-recurrent congestion" by Dr. Chang, Park, and Nan, has received the 1st rank among all projects submitted by all nationwide university research centers for the USDOT sponsored 2011 Research Demonstration/Exhibition event, and is invited to make the podium presentation at USDOT on April 6th.

11.   Maryland Unconventional Intersection Design (MUID) presentation.
