MOT Support Services for I-75 Eastbound Ramp to SB SR 826
The eastbound exit ramp from eastbound I-75 to southbound SR 826 is under construction. The ramp currently experiences high levels of congestion during the morning peak hour which is expected to increase during construction. The objective of our study is to determine the increase in travel time for the eastbound I-75 to southbound SR 826 traffic movement as a result of construction on the eastbound I-75 exit ramp and to monitor the critical phases of construction. As part of the tasks for this project ATEC performed travel time and delay data for the "before" and "during construction" conditions. Our team used the Traffic Camera System (TCS) to perform traffic counts; also ATEC prepared a Multimedia which includes animations for travel time and videos recorded in the field during peak the hours.
Also, our clients were able to have access to the real time cameras.

Evaluation of the Removal of the Flyover Ramp from WB SR 836 to SB SR 826
ATEC was retained by FDOT District SIX to perform an advanced VISSIM traffic Microsimulation analysis to evaluate the performance of the interim MOT phase of the reconstruction of SR 826/SR 836 system to system interchange. The MOT phase consists of removing the westbound SR 836 to southbound SR 826 flyover-ramp. Traffic will be diverted to the loop ramp from westbound SR 836 to southbound SR 826 that will be widened to dual lanes. The main objectives of the study were to quantify the impacts of the flyover ramp removal in terms of additional travel times for the westbound movement from SR 836 to southbound SR 826, and to develop alternative strategies to minimize travel time, reduce conflict and the need for lane changes, and enhance safety.
The FDOT Resident Engineer and design-build team of consultants approved the study conclusion and changed the MOT plan as recommended by the ATEC study.
PD&E Study Golden Glades Interchange from SR 826 to I-95 NB
ATEC as a sub-consultant to C3TS is currently performing the operational analysis for the Golden Glades Interchange (GGI) PD&E study. GGI is one of the most complex interchanges in Florida. It connects three major freeways (I-95, Palmetto Exp. and Turnpike) and three major arterials (SR 7, SR 9 and NW 167 Street). It carries over 400,000 vehicles per day and is critical for inter-county travel and the transportation of goods and services. The operational analysis conducted by ATEC will consider future improvements including a direct connection between eastbound Palmetto Expressway and northbound I-95, and an ultimate plan providing a network of managed lanes. The analysis is being performed using CORSIM micro-simulations and will implement the latest 2010 Highway Capacity Manual procedures.
A successful completion of this project will reduce delays and enhance the overall mobility in South Florida for commuters, visitors and truck traffic; for both local and regional trips.
