Perimeter Circulator ProjectOctober 19, 2000Steering Committee Meeting

TASK 1.0 GOALS & OBJECTIVES

Study Goals

To better prepare the (DCID) to seek and obtain state and federal financial assistance toward project implementationTo quantify the order of magnitude of first cost and annual cost toward a go/no-go decision

Project Goals1.To encourage lessened use of single-occupancy motor vehicles 2. To provide an effective public system of local distribution for regional trip-makers3. To enhance the economic development and tax base of Perimeter Center by increasing the density of land usage without incurring adverse impacts.4. To assist the community in achieving air quality goals.

Project Goals Continued5. To make the offices, retail establishments, medical facilities, hotels, and employment opportunities more accessible to all patrons and employees.6. To offer local trip-makers an effective alternative to autos, shuttle buses and surface transit.7. To help preserve greenbelts and park areas potentially threatened by need for added parking facilities.8. To take advantage of opportunities for facilitating circulator placement and location in coordination with scheduled improvements to freeways.

Goal Suggested During the First Stakeholder MeetingTo provide a public system that allows flexibility within the Perimeter Center area and allows future expansion beyond this area.

FindingsPerimeter area is the most dense employment concentration outside central AtlantaDekalb County portion of the study area is currently much more intensely developedFulton County portion of the study area shows largest potential for future growthData sources reviewed are relatively consistent in growth estimatesOffice/Mixed use is largest component of future land usageOffice/Mixed use allows mix of uses as influenced by market forces

TASK 3.0 TECHNOLOGY ASSESSMENT

Characteristics & RequirementsState-of-the-art technology (Modern & Attractive)Electrically powered (To meet clean-air goal)Fast speed (Right-of-way permitting)Quick Loading and Off-Loading from either sideComfortable interior (air conditioned, blend of seating/standing capacity)ReliabilityAccessible conformance with Federal ADA 90 & Safety conformance with NFPA 130

Light Rail Transit (LRT) (Siemens Five-Module Combino)

Light Rail Transit (LRT)(Siemens Five-Module Combino)Most Flexible mode for Placement Can operate at 55 mph; Make short radius turns; & climb grades up to 7%Simple & Fast Switching Capability using large, single running carsManned Operations, but with automatic train protectionVehicles are generic & generally non-proprietary attracting bid competition (Least expensive of three modes under consideration)Capability of Operating at Grade where vehicles/pedestrians cross right-of-way (Could cause negative impact on other traffic movements)

Monorail (Bombardier/TGI M-VI Monorail)

Monorail(Bombardier/TGI M-VI Monorail)Trains made up of small car modules running on rubber tires and straddling a concrete girder (signature image of Disney World)Fully elevated, can operate close to grade with isolated right-of-wayOperates up to 40 mph; is limited to curves of 300 ft. radius or greater; and can climb grades up to 6.5%Manned operations, but with automatic train protectionSwitching by beam-replacement transfer table (Slower & less Reliable)Least Flexible of modes in terms of PlacementVehicles are proprietary and not competitively available (High cost mode due to uniqueness and geometric limitations

Automated Guideway Transit (AGT) (Adtranz Innovia or CX-100)

Automated Guideway Transit (AGT)(Adtranz Innovia or CX-100)Trains of small cars, operating on rubber tires bearing on concrete guideway (steered and switched by follower on center guiderail)Operates up to 48 mph; make short radius turns; & climb grades to 8%Generally flexible in terms of PlacementOperates fully grade separated (fully automated or remote controlled)Generally elevated (Can operate close to grade with isolated right of way)Vehicles are proprietary but comparable designs offered by other suppliers (Most costly of considered modes)

TASK 4.0 PRELIMINARY ALTERNATIVE ROUTES

ROUTE DEVELOPMENT CONSIDERATIONSMarta Station locations - Walking distancesHigh concentration employment - Divided into ZonesUtilize future traffic improvement (Fly-Over bridge)Consider Marietta/Lawrenceville Study/Findings

ALIGNMENT ONETwo Intersecting Loops Oriented North-SouthComprised of two dual-guideway loops which share a common guideway at their intersectionThis alignment can be implemented with any of the three technologies under evaluationInterfaces with four MARTA Stations in the study area Operations on both loops interface at Dunwoody MARTA StationSub-alternates routes to be compared

ALIGNMENT TWOTwo Intersecting Loops Oriented East-WestAlternate was developed to differ from Alignment One where MARTA coverage Retains a common guideway between the two loopsThis alternate allows any of the three technologies to be utilizedInterfaces with three MARTA Stations:Operations on both loops interface at Dunwoody MARTA StationSub-alternates are indicated for comparison

ALIGNMENT THREESingle Loop with Branches to Northern DevelopmentsContains southern loop as shown in Alternate Two with independent branch lines serving the northern developmentsBranch lines provide means for future growth or expansionInterfaces with two MARTA StationsLoop and branches converge at Dunwoody MARTA Station

ALIGNMENT FOURAt-Grade Light Rail Radial SystemRestricted to one technology - light rail transitLRT would coexist with surface traffic and would deliver patrons closer to their destinationPenetrates centers of concentrated employmentInterfaces with Dunwoody MARTA StationWould require street widening so as to not lessen street capacityEasily lends itself to phased constructionLeast cost system for a given mileage coverage
