TRAFFIC MANAGEMENT TECHNIQUES & APPLICATIONS

TRAFFIC MANAGEMENTTECHNIQUES & APPLICATIONSAmit Ranjan ChitranshiAkash BhatnagarMTech(Transportation Engineering)Transportation System Management (TSM)Application of methods & procedures for increasing the efficiency & utilization of existing facilities.

Emphasis on making better use of existing resources rather than planning new

Objective is to shift the focus from high capital approaches to low cost, more rapid implementable projects.

Travel Demand ManagementVolume vs Time and Peak Hours Capacity

Methods for Influencing the DemandShifting the temporal distribution of demandsReducing the Magnitude of DemandRepackaging the demand

Shifting the Temporal DistributionMethods aim at flattening the volume-time curve at peak hours.Achieved by Staggered Working HoursFlexible Working Hours

Reducing the Magnitude of DemandMethods aim at reducing the traffic demand at around a place.Achieved by:Shorter working weeksShorter Average trip length by shifting city centres to smaller cities & decentralized locationsWork from home facilityRepackaging the DemandMethods stress on the mode of transport to influence the demand.Achieved by:Better facility of public transportEncouraging/compulsory car poolingParking RestraintPriority for busesTraffic ManagementRetaining the existing pattern of streets but altering the pattern of traffic movement on these.Reorienting traffic pattern on the existing streets so that the conflicts between vehicles and pedestrians is reduces.Traffic Management MeasuresRestriction on turning movementsSeparate turning phase in signalsProhibition on turning movementOne way StreetsTidal Flow OperationsExclusive Bus LanesAdvantage of One Way StreetsReduction in points of conflictsIncreased capacityIncreased speedProgressive SignalsImproved ParkingElimination of head on collision

Disadvantage of One Way StreetsIncreased distanceRelocation of bus stopsIncreased severity of accidents due to speedAdverse effect on business of areaPrerequisite need of alternate street systemBottleneck to emergency vehicles
