Conceptual Overview

 I-75 Express Lanes is identified as a Tier 1

recommendation in the Managed Lane System Plan, adopted by the State Transportation Board in December 2009.

 From the MLSP GDOT recognized that:

 Managed lanes would be defined as a set of lanes where operational

strategies are proactively implemented and managed in response to changing conditions.

 Managed lanes are considered to be complementary treatments to metro

Atlanta’s interstate network

 Managed lane solutions would preserve mobility choices and likely represent

the most appropriate and cost beneficial improvements.

 Transportation needs have outpaced traditional revenue sources  In some locations it is not feasible to build all the additional lanes necessary

to meet current and future needs.

Why Is This Project Important?

 I-75 is an important local and regional corridor

 One of the nation’s most traveled highways, especially in metro Atlanta  Primary connection between jobs and fast-growing Henry County

 Safety, travel demand, regional growth and accessibility

are major issues

 Transportation investments are the solution

 Improve roadway capacity, accessibility, efficiency  Address safety -- increased traffic congestion increases crash frequency  Context of Traffic volumes between SR 155 and I-75/675 lends credible

  • pportunity for a ML solution

Project Facts

 The project will add two reversible barrier separated

managed lane system along I‐75 in Henry and Clayton Counties from SR 155 to SR 138 for 12.24 miles.

 The express lanes are designed to improve the flow of

traffic, increase travel options for motorists, transit and registered vanpool customers, provide reliable trip times, create jobs and bring economic benefits to the residents of this region.

 The project funding sources: state-motor fuel, federal

aid and toll revenue bonds.

Reversing I-75 South

 Typically two reversals per day

 Mid-day reversal for outbound evening commute  Late-night reversal for the inbound morning commute

 HERO units will be on-site during all reversals

 Two dedicated units required for reversal

Check that the gates open/close properly at every entry and

exit point

Can access the ACS cabinet to start/continue the reversal (if

reversal fails

  • A. Gillespie
slide-31

Access Points

Reversals are completed by Access Point Each Access Point contains equipment for both

entrances and exits

 Gates  Signs  Toll points  Signals/Blank-out Signs

Order of operations is pre-determined, site-specific, and

  • peration specific

Trip Building by Project

I-85 Express

 Trip may include a single

tolling segment or multiple tolling segments

 A minimum of two gantry

reads per segment are necessary to form a valid trip

 Minimum number of reads to

form shortest trip is two

 Maximum number of reads to

form longest trip is 34

I-75 South

 No concept of a tolling

Segment

 Entry/exit transactions are

used to create trips

 Two gantry reads are required

to form shortest trip and longest trip

Toll Pricing – I-85 Express

  • Static, variable, or dynamic
  • I-85 Express Lanes are a

combination of all of the above

  • Minimum rate per mile $0.01,

Maximum rate per mile $0.90

  • Dynamic tolls are calculated

using live traffic speeds and volumes from both the EL and the GP lane

  • Trip rate is calculated per

mile, locked in at point of entry.

  • Signage is based upon

next/last destination

  • Designated weave areas for

ingress/egress.

a combination of the above

  • Minimum – Flat $0.50,

Maximum rate per mile is $0.90

  • Dynamic tolls are calculated

using live traffic speeds and volumes from both the EL and the GP lane

  • Trip rate is segment based,

locked in at point of entry

  • Signage is based upon

next/last destination
