Definition

Traffic management =

Influencing of traffic (flow) and transportwith operational measures based on

defined goals

(without major infrastructure measures high cost-effectiveness)


4/24Institute for Transport Studies, BOKU Vienna 4

Types of Traff ic Management Measures

Traffic management of trafficinfrastructure (with and without ITS)

Travel information service

Mobility management for firms andcompanies

Travel behaviour change program

etc.



Goal of Traff ic Management Measures

Influencing traffic to

improve the environment promote the economic

development

achieve a high social standardfor the whole population

sustainabletransport

development

Need of suitable evaluation tool(SDA = Sustainable Development Analysis)



Example 1

Bus Priority Measure underHeterogeneous Traffic Condition

Results of phd-thesisof P. Vedagiri, Madras



The Problem

Congested arterial roads inconurbation

no space for wideningno sense of widening

Two principle alternatives

underground new distributionrailway of road space



Lane-Based Homogeneous Traff ic Flow

Vedagiri 2009



Non-Lane-Based Heterogeneous Traff ic Flow

Vedagiri 2009



Bus Lane for 14.5 m Wide Urban Road(Dual Carr iage Way)

Example 2

Parking Management Scheme for

Private Car Parks

Results of a Research Study forthe Vienna Region

ITS, BOKU


15/24


The Problem

Parking management and paid parking zones in publicspace very efficient traffic management measure

Problem: increasing number of private parking slots commuter car parks, car parks of shopping centresetc.

Two options of solution

congestion pricing parking management for

private car parks

O t i f k i t f


16/24


Opt ions of park ing management measures forpr ivate car parks

1 Obligatory limitation of the maximum number of private parking slots for customers andcommuters

2 Parking space levy for operators of large privatecar parks20 to 60 /month, parking slot

3 Obligatory parking fees for customers (0,80 to1,80 /h) and commuters (20 to 60 /month,parking slot)

4 Maximum trip quotas in combination with mobilitymanagement for customers 20 to 200 cartrips/day,1000 m2 gross floor area, penalty

73 % influence on the decision of location problem at boundary of zones with different

tax level equal treatment of all location is important

100 % passing the cost to customers

27 % jeopardizing of existing location of shoppingcentres

64 % reductions of number of parking slots

Opinion of Operators and Developersparking space levy for shopping centres


21/24


Strong demand effects, mitigation of congestion

Recommendation for combined measuresOPPS + parking space levy

Recommendation for application

- in low density areas outside cities- increased graduation of levy dependent onincreasing car-orientation

Limitation of car trips for shopping centres- possible application in air quality redevelopmentareas

- further research needed

Recommendation


22/24


Short term effects for shopping trips- Omitted trips (deduced traffic) up to one quarter consumer loss

- Change of destination for shopping trips up to onequarter weakening of shopping locations appropriate zones for shopping centres with

obligatory parking management measures? problem of fair competition for obligatory

zones with differentiated level of quota

Long term effectsStrong effect on location choice for shopping centres appropriate locations for obligatory OPPS

boundary problem? Further research recommended

At t ent ion of Not Negligible Side Ef fect s

Conclusion

Traffic management very effective

Attention to not negligible side effects Cost-effective contribution for

sustainable transport policy
