WHATISANMBUFSYSTEM?

America’sroadsarepaidforthroughavarietyofmeans:fueltaxes,tiretaxes(fortrucks),vehicleregistrationfees,tolls,generalfundrevenues(includingsalestaxes),andothers.Inthelast

decade,anumberofgovernments,includingsomeforeignandU.S.stategovernments,havebegunexperimentingwithcollectingrevenuedirectlyfromdriversonthebasisoftheirtravel.

Therearemanytermsforthis,includingMBUFs,distance-baseduserfees(DBUFs),avehiclemilestraveledtax(VMTT),androadusagecharges(RUCs).Theideaispaymentsshouldbe

basedonactualtravel,includingtimesofdayandroadstraveledon.Anumberofstates,

includingCalifornia,Colorado,Delaware,Hawaii,Minnesota,Oregon,Pennsylvania,and

Washington,havelaunchedpilotRUCprograms,mostwithpartialfederalfunding,whilea

numberofotherstatesareconsideringsuchprograms.TheU.S.DepartmentofTransportation(DOT)hasfundedanumberofroundsofstateRUCpilotprograms.AmajorfactormotivatinginterestinanMBUFsystemistheconcernthatwiththeexpectedriseofmorefuel-efficient

Therearetwomainwaystocollectmileage-basedfees.Thefirstisbasedonasimpleannualodometerreading,withafeebasedonthenumberofmilesavehiclehasdriven.Thisis,

however,nottheoptimalwayofcollectingthefee,becausethecostsimposedonthe

morefuel-efficientvehicles,especiallyEVs,governmentswillbeunabletoobtainadequaterevenuestosupporttransportationinfrastructure.

Suchasystemwouldworkasfollows.NewvehicleswouldcomeequippedwithanOBU,aGPS

receiver,andcellular-communicationscapability.Innewvehicles,theOBU(orthevehicle’smappingsystem)wouldcontainadatabasewithalltheroadsintheUnitedStatesand

informationonpricesforeachsegment,includingbytimeofdayandwhatentity(local,state,andfederalgovernmentorprivatetolloperator)wouldreceivethepayment.Whenjurisdictionschangeroadprices,regularupdateswouldbedownloadedtotheOBUs.TheOBUwould

calculatepaymentstoallthejurisdictionsbasedontheroadsegmentsavehicledroveonandthepriceofthesegmentatthetimeoftravel(e.g.,$1.30toMontgomeryCounty,Maryland;

$5.15tothestateofMaryland,and$6.47tothefederalgovernment).Attheendofeach

month,avehicle’sOBUwouldaggregatethevariousfeesandsendapaymenttotheappropriatelocal,state,orfederalagency—oraprivate-roadowner—byautomaticallychargingthevehicleowner’screditcardorbankaccount.Forindividualswithoutacreditcardorbankaccount,thetotalpaymentamountcouldbeaddedtotheirannualorbiennialvehicleregistrationfees.

Importantly,theonlypersonallyidentifiableinformationtheentitieswouldreceivewouldbe

WHYTRUCKS?

AkeybenefitofdeployingaGPS-basedMBUFsystemwouldbetheabilitytobetteralignthe

costsheavytrucksimposeonthetransportationsystemwiththefeestheypay.Economistsin

general,andtransportationeconomistsspecifically,agreethateconomicallocationefficiencyismaximizedwhenpricesreflectcostsimposed.Ifaneconomicactivityissubsidized—inthecaseofheavytrucks,bynotpayingthefullcoststheyimpose—theeconomywillbelessefficientandoveralloutputwillbeless.

Itisclearthatheavyvehiclesimposegreatercosts.Asoneacademicstudystates,“Asroadwearisverytightlycontrolledbyaxleload,itbecomesapparentthatlargervehiclessuchas[heavy

weight.”

HOWWOULDATRUCKMBUFSYSTEMWORK?

AsuccessfultruckMBUFsystemwouldbedesignedsuchthattrucksoveracertainsizeand

addition,truckswouldberequiredtohavesensorstomeasureweightperaxle.Truckswouldpaybasedonanumberofdifferentfactors:thetruckaxleweight(heaviertruckswouldpaymore);

setuptocollectandremitbothstateandfederaltaxes.Chargesshouldbesettoensurethatthechronicsubsidizationofheavytruckingiseliminatedandthattrucksassumetheirfull

TRUCKINGINDUSTRYOPPOSITION

Anyindustrythatisprotectedorsubsidizedbygovernmenthasamajorstakeinprotectingthoseadvantages,andthetruckingindustryisnodifferent.IntheiradvocacyagainstatruckMBUF,theymakeanumberofflawedarguments.

Claim1:TruckingAlreadyPaysaLot

Thetruckingindustryclaimsthatsincetrucksalreadypayalotinvariousfeesthatanyincreaseisunfair.Butthat’sabitlikesomeonesayingtheyalreadypayalotontheirmortgage,even

thoughthepaymentsdon’tcovertheprinciple.Theissueisnothowmuchtruckerspay,orwhatthetrendsinpaymentsare;it’showmuchdotheypayrelativetothecoststheyimpose?Andasnoted,theevidencesuggeststhattheindustrydoesnotpayenough.

Ofcourse,thetruckingindustrycriesthatitwouldbediscriminationiftheyweretohavetopaymoreandhaveanMBUF.AsatopofficialattheAmericanTruckingAssociationwroteinalettertoCongress:

Ourindustryhaslongsaidwearewillingtopayourfairsharetofinanceneeded

nation’sinfrastructureneedsandwillstronglyopposeanyefforttodoso.

IfhewerecomplainingaboutthepossibilityofCongressraisingtheirfeesabovewhattheiractualcostswere,thenhewouldhavealegtostandon.ButcomplainingthatCongressmightraise

window:“That’sdiscriminatory.Can’tIjustpayhalfandhavealltheneighborspaytherest?”

Claim2:IncreasedPricesforConsumers

Theindustryplaysthesmalltruckersympathycard,claimingwronglythatincreasedfees(to

matchthecoststheyimpose)wouldputindependenttruckersoutofbusinessandraisecostsforconsumers.But,bydefinition,theycan’tdoboth.Eithertruckersabsorbthehigherfeesortheydon’t.Therealityisthatiftruckcostsgoup,twothingswillhappen.First,atthemargin,therewillbeashifttoothershippingmodesforparticularrouteswheretheyareinherentlymore

Second,totheextentcostsgoupfortheroutesonwhichshippersstillusetrucks,bydefinition,thecostswillgetpassedontoconsumers,aslongastruckingmarketsarecompetitive.Whiletheindustrymaynotbeabletopassalongallthecostsoftargetedtollstocustomersintheshort

Butthatisnotthefullstory.Becausetruckswouldnowbepayingmoreinroadfees,automobile

andlight-dutytruckdriversandtaxpayerswouldpayless,completelycancelingoutanyincreaseinshippingcosts.Anyargumentthatconsumerswillsufferfromendingtrucksubsidiesisjustwrong.

Finally,becausetruckswouldbepayingthetruecosttheyimposeonthetransportationsystem,therewouldbelessroaddamage,inpartbecausetheywould,atthemargin,switchtomore
