8 TRANSITDEPENDENTANDSPECIALFACILITYEVACUATIONTIMEESTIMATES

Thissectiondetailstheanalysesappliedandtheresultsobtainedintheformofevacuationtime

estimates for transit vehicles. The demand for transit service reflects the needs of three

populationgroups:(1)residentswithnovehiclesavailable;(2)residentsofspecialfacilitiessuch

as schools, medical facilities, and correctional facilities; and (3) homebound special needs

population.

These transit vehicles mix with the general evacuation traffic that is comprised mostly of

passengercars(pcs).Thepresenceofeachtransitvehicleintheevacuatingtrafficstreamis

representedwithinthemodelingparadigmdescribedinAppendixDasequivalenttotwopcs.

Transit vehicles must be mobilized in preparation for their respective evacuation missions.

9 TRAFFICMANAGEMENTSTRATEGY

Thissectiondiscussesthesuggestedtrafficcontrolandmanagementstrategythatisdesigned

to expedite the movement of evacuating traffic.  The resources required to implement this

strategyinclude:

  • Personnel with the capabilities of performing the planned control functions of traffic

guides(preferably,notnecessarily,lawenforcementofficers).

  • TrafficControlDevicestoassistthesepersonnelintheperformanceoftheirtasks.These

devices should comply with the guidance of the Manual of Uniform Traffic Control

Devices (MUTCD) published by the Federal Highway Administration (FHWA) of the

U.S.D.O.T. All state and most city/county transportation agencies have access to the

MUTCD,whichisavailableonline:http://mutcd.fhwa.dot.govwhichprovidesaccessto

theofficialPDFversion.

  • A plan that defines all locations, provides necessary details and is documented in a

formatthatisreadilyunderstoodbythoseassignedtoperformtrafficcontrol.

AllcountiesandcitiesintheSPSEPZhavedetailedevacuationtrafficcontrolplans.AttheAlert

law enforcement personnel would be placed on standby and an assessment made, at the

Theterms"facilitate"and"discourage"areemployedratherthan"enforce"and"prohibit"to

The implementation of a plan must also be flexible enough for the application of sound

manpower and equipment needs, while still facilitating the evacuation process. Dynamic

Message Signs (DMS) can be placed within the EPZ to provide information to travelers

regardingtrafficconditions,routeselection,andevacuationassemblycenterinformation.DMS

canalsobeplacedoutsideoftheEPZtowarnmotoriststoavoidusingroutesthatmayconflict

withtheflowofevacueesawayfromthepowerplant.HighwayAdvisoryRadio(HAR)canbe

atleast80percentofthepopulationwithintheEPZwillcomplywiththeAdvisorytoEvacuate.

Onthisbasis,ananalysiscouldbeundertaken(seeTable121)toyieldanestimatedsample

sizeofapproximately300.

Theconfirmationprocessshouldstartatabout3hoursaftertheAdvisorytoEvacuate,whichis

when approximately 90 percent of resident evacuees have completed their mobilization

activities (see Table 59). At this time, virtually all evacuees will have departed on their

respectivetripsandthelocaltelephonesystemwillbelargelyfreeoftraffic.

As indicated in Table 121, approximately 71/2 person hours are needed to complete the

telephone survey.  If six people are assigned to this task, each dialing a different set of

telephone exchanges (e.g., each person can be assigned a different set of PAZs), then the

requiredtoundertakethistypeofconfirmationsurvey.

Ifthismethodisindeedusedbytheoffsiteagencies,considerationshouldbegiventomaintain

a list of telephone numbers within the EPZ in the EOC at all times. Such a list could be

purchased from vendors and could be periodically updated. As indicated above, the

that households have had enough time to mobilize. This 3hour timeframe will enable

13 RECOMMENDATIONS

Thefollowingrecommendationsareoffered:

1. Examination of the general population ETE in Section 7 shows that the ETE for 100

percentofthepopulationisgenerally11/2to4hourslongerthanfor90percentofthe

population. Specifically, the additional time needed for the last 10 percent of the

populationtoevacuatecanbeasmuchasfourtimesthetimeneededtoevacuate90

percent of the population. There are two contributing factors that lead to this non linearity:

a. Relativelyfewstragglersrequiresignificantlymoretimetomobilize(i.e.prepare

for the evacuation trip) than their neighbors. This leads to two

recommendations:

i. Thepublicoutreach(information)programshouldemphasizetheneed

forevacueestominimizethetimeneededtopreparetoevacuate(secure

thehome,assembleneededclothes,medicines,etc.).

ii. The decision makers should reference Table 71 which list the time

needed to evacuate 90 percent of the population, when preparing

recommendedprotectiveactions,asperNUREG/CR7002guidance.

b. ThereisintenseandprolongedcongestionontheroadwaysexitingtheEPZnorth

When the road network under study is large, multiple routing options are usually available

betweentriporiginsanddestinations.Theproblemofloadingtrafficdemandsandpropagating

them over the network links is called Network Loading and is addressed by DYNEVII using

macroscopic traffic simulation modeling. Traffic assignment deals with computing the

distributionofthetrafficovertheroadnetworkforgivenODdemandsandisamodelofthe

route choice of the drivers. Travel demand changes significantly over time, and the road

networkmayhavetimedependentcharacteristics,e.g.,timevaryingsignaltimingorreduced

road capacity because of lane closure, or traffic congestion. To consider these time

dependencies,DTAproceduresarerequired.

A telephone survey of households within the EPZ was conducted to identify household

theEPZpopulation.Thisinformationwasusedtodetermineimportantstudyfactorsincluding

theaveragenumberofevacuatingvehiclesusedbyeachhousehold,andthetimerequiredto

performpreevacuationmobilizationactivities.

Step6

A computerized representation of the physical roadway system, called a linknode analysis

network,wasdevelopedusingtheUNITESsoftwaredevelopedbyKLD.Oncethegeometryof

thenetworkwascompleted,thenetworkwascalibratedusingtheinformationgatheredduring

the road survey (Step4). Estimates of highway capacity for each link and otherlinkspecific

characteristicswereintroducedtothenetworkdescription.Trafficsignaltimingswereinput

accordingly.ThelinknodeanalysisnetworkwasimportedintoaGISmap.2010Censusdata

were overlaid in the map, and origin centroids where trips would be generated during the

evacuationprocesswereassignedtoappropriatelinks.

Step7

TheEPZissubdividedinto30PAZs.Basedonwinddirectionandspeed,Regions(groupingsof

PAZs)thatmaybeadvisedtoevacuate,weredeveloped.

The need for evacuation can occur over a range of timeofday, dayofweek, seasonal and

weatherrelatedconditions.Scenariosweredevelopedtocapturethevariationinevacuation

demand,highwaycapacityandmobilizationtime,fordifferenttimeofday,dayoftheweek,

timeofyear,andweatherconditions.

Step8

TheinputstreamfortheDYNEVIImodel,whichintegratesthedynamictrafficassignmentand

distributionmodel,DTRAD,withtheevacuationsimulationmodel,wascreatedforaprototype

evacuationcase-theevacuationoftheentireEPZforarepresentativescenario.

Step9

After creating this input stream, the DYNEV II System was executed on the prototype

evacuationcasetocomputeevacuatingtrafficroutingpatternsconsistentwiththeappropriate

NRC guidelines. DYNEV II contains an extensive suite of data diagnostics which check the

completenessandconsistencyoftheinputdataspecified.Theanalystreviewsallwarningand

error messages produced by the model and then corrects the database to create an input

streamthatproperlyexecutestocompletion.

The model assigns destinations to all origin centroids consistent with a (general) radial

evacuation of the EPZ and Shadow Region. The analyst may optionally supplement and/or

replacethesemodelassigneddestinations,basedonprofessionaljudgment,afterstudyingthe

topology of the analysis highway network.  The model produces link and networkwide

Step10

The results generated by the prototype evacuation case are critically examined. The

examination includes observing the animated graphics (using the EVAN software which

operatesondataproducedbyDYNEVII)andreviewingthestatisticsoutputbythemodel.This

isalaborintensiveactivity,requiringthedirectparticipationofskilledengineerswhopossess

thenecessarypracticalexperiencetointerprettheresultsandtodeterminethecausesofany

problemsreflectedintheresults.

Essentially, the approach is to identify those bottlenecks in the network that represent

locations where congested conditions are pronounced and to identify the cause of this

congestion.Thiscausecantakemanyforms,eitherasexcessdemandduetohighratesoftrip

generation,improperrouting,ashortfallofcapacity,orasaquantitativeflawinthewaythe

physical system was representedin the input stream. This examination leads to one of two

conclusions:

x Theresultsaresatisfactory;or

x Theinputstreammustbemodifiedaccordingly.

Thisdecisionrequires,ofcourse,theapplicationoftheuser'sjudgmentandexperiencebased

upontheresultsobtainedinpreviousapplicationsofthemodelandacomparisonoftheresults

of the latest prototype evacuation case iteration with the previous ones.  If the results are

satisfactoryintheopinionoftheuser,thentheprocesscontinueswithStep13.Otherwise,

proceedtoStep11.

Step11

There are many "treatments" available to the user in resolving apparent problems.  These

treatments range from decisions to reroute the traffic by assigning additional evacuation

destinations for one or more sources, imposing turn restrictions where they can produce

significantimprovementsincapacity,changingthecontroltreatmentatcriticalintersectionsso

as to provide improved service for one or more movements, or in prescribing specific

treatmentsforchannelizingtheflowsoastoexpeditethemovementoftrafficalongmajor

NUREG/CR7002 indicates that the existing TCPs and ACPs identified by the offsite agencies

As discussed in Section 9, traffic control points at intersections (which are controlled) are

the intersection is identified as a traffic control point, the control type was changed to an

orabove,trafficbarrierswouldbedistributed,asneeded.

G.2 AccessControlPoints

It is assumed that ACPs will be established within 2 hours of the advisory to evacuate to

discourage through travelers from using major through routes which traverse the EPZ.  As

discussed in Section 3.6, external traffic was only considered on I64, in this analysis.  The

generation of these external trips ceased at 2 hours after the advisory to evacuate in the

simulation.
