33 High Productivity Freight Vehiclesvity freight vehicles Re-inventing the wheel? A 66-tonne truck with 9 axles and trailer-axle steering mechanisms, from

34 What is productivity? Productivity can be defined as freight efficiency Any method which allows extra mass/volume to be carried Can be very simple (e.g. increased length), or quite involved (e.g. entirely new vehicle designs) Payload efficiency Volume efficiency 34

35 Local advances in productivity Many advances in productivity over the years Productivity improvement Gross vehicle mass (GVM) increase Year 1950s Trailer length increase 1989 Introduction of B-doubles 1990 s Increases in cubic capacity 1997 Truck and dog trailer improvements 1997 Introduction of PBS 2000s 35

36 B-doubles: a case study The impetus for B-doubles: only slightly longer than a semi-trailer one extra axle group allows more payload First request from Shell Australia in 1979 Twelve years later, 500 B-doubles in operation, and approvals or trials in most Australian states 36

41 Productivity in terms of vehicles GCM (t) Length (m) Payload (t) Volume (m 3 )

42 Productivity in terms of vehicles Vehicle type B-double 35% increase in payload and volume 27% increase in length 42

43 Productivity in terms of vehicles Vehicle type B-triple 43% increase in length 56% increase in payload and 52% increase in volume 43

44 Performance Based standards

45 What is the PBS scheme? Performance Based Standards, established 2008 Innovative regulatory scheme for innovative vehicles Focuses on what the truck can do, not what it looks like Network access is based on vehicle performance 16 safety standards and 4 infrastructure standards Source: NTC 45 45

46 Why do we have the scheme? The demand for freight is increasing Freight demand in 2050 will triple that of 2006 Source: Infrastructure Partnerships Australia, Meeting the 2050 Freight Challenge

52 Vehicle Classification Criteria

53 53 Why is maneuverability an important consideration?

54 Overview Why is low speed manoeuvrability important? How do we measure it? What vehicle factors affect performance? Practical tools and assessment methods 54

55 Low speed swept path (LSSP) The maximum width of the swept path of the vehicle simulated driving through a 90º turn of 12.5 m radius at a speed of 5 km/h 55

56 Typical performance levels What are the typical performance levels for a range of different vehicles 56

57 Static rollover threshold (SRT) The vehicle driven along a tight radius path increasing the speed at a slow, steady rate until the point of rollover. PBS Performance Targets Dangerous goods & buses: > 0.40g Other vehicles: > 0.35g 57

58 Testing rollover stability Target 28 degrees 58

59 Vehicle assessment High speed lane change manoeuvre Left screen shows a vehicle undergoing a full lane change manoeuvre during an ARRB testing program. The driver must follow the yellow markers. Right screen shows the same manoeuvre using computer simulation. The four white lines represent the maximum off-tracking permitted for each level. Note this vehicle does not exceed Level 1 (0.6m). 59

60 Tracking ability on a straight path TASP is determined by the maximum swept width obtained from the lateral movement of a vehicle when it is travelling along a section of road with a varying profile. The total swept width while travelling on a straight path, including the influence of variations due to crossfall, road surface unevenness 60

61 Tracking Ability on a Straight Path (TASP) Measured by simulation 61

62 Longitudinal performance 62

63 Route Assessment Principles

64 Route assessment benefits Achieves consistency in classification across jurisdictions Identifies the weak links and allows prioritised plans Can support access and compliance monitoring 64 64

65 Route assessment guidelines Advances in innovative policy (PBS), vehicle assessment and data collection and processing Used to develop a more comprehensive approach to route assessment and access decision making NTC s Network Classification Guidelines published in

66 Route assessment guidelines Managing road characteristics in accordance with aspects of vehicle performance that relate to access Acceleration performance Turning performance Road space requirements Road and bridge widths Overtaking provision Entry length onto main roads and highways Approach visibility Vertical (overhead) clearance Off-road truck parking Roadside infrastructure 66

67 The route assessment process A particular route or set of routes is defined Road/route data is collected or collated The classification guidelines are applied The access Levels are determined Lane width Level 1 Shoulder width Grade AADT volume Level 2 Level 3 intersections Level 4 67

68 Roads owned by local government (comprising 85% of the transport network) were not captured The NTC guidelines are not suitable for local government road networks Are constantly facing requests for access, with few alternatives or options 68

73 What s it all about?

74 What is PBS RAT? PBS Route Assessment Tool for Victorian Local Govt ARRB - MAV Project Development of LG guidelines and On-line software tool

75 Where Does PBS Fit In? Supplements not replaces Local manager decision making!

76 How the Tool Helps You Push for HPV access to local roads, National Regulator means a change in responsibilities for LG Goal is to achieve consistency in route classification (access) by using a tool that is: Suitable for local government Easy to use, quick or detailed Support for both near-zero and rich data inputs Simplifies PBS guidelines for local road infrastructure Exists to make life easier and support local managers Repeatable and traceable workflow and record for access decisions in local area

77 Supplementing Existing Access Processes Tool supplements, not replaces existing process PBS RAT provides a practical technical classification More detailed classification possible using Guidelines Ultimate decision is still Local Road Manager System Publishes completed routes to 3 rd parties

78 PBS RAT Features Web-based tool (PBS RAT) - No special software required System supports, educates and simplifies local government HV access decision making Provides both classification and indication of classification reliability

79 Operation Overview

80 Pinch Points Assumes highest level of access, but lowest reliability Considers routes in terms of its restrictive limitations (pinch points) Allows for progressive classification of routes with quick and dirty followed by adding more detail Lane Width (2B) Signal Timing (2A) Swept Path (3A) Storage Lane Length (2B) Actual route classification (2A) is the lowest access level granted by these restrictive features

81 You can estimate then confirm later Ranges rather than absolute values, user can specify level of certainty and update later if seen to be critical

82 Sometimes you already Know the Answer! Practicality with understanding constraints on local government.

83 Design Features You can pick the eyes out, do classification by road section or by PBS classification item.

105 Route Setup Guidelines You must add all bridges and railways crossings along a route since these are special cases. You can re-visit this screen later if you make a mistake, and edit the route. The system will automatically detect existing (pre-classified) sections of routes

106 System Outputs PBS Classification Score (PBS level 1-4 a/b) Detailed classification reports, including pinch point(s) Consolidated published route reporting area Mapping outputs - route and location Data export linkages through road ID s etc Additional linkages to be considered in national context SRO s Research PBS RAT NHVR National Route Maps

107 Reports and Outputs Reporting Survey drive sheets for things to check/measure on the route Detailed route classification reports Route response audit reports Network summary reports CSV download

108 Privacy and Security The system is designed to support local manager decisions, therefore: Your routes are shared within your organisation only All information is private and secure, some reporting for support and research purposes only (anonymous and aggregated data only) Only the results of completed routes that you choose to publish are made available to other authorities No details, comments or inner workings are released:

109 Typical Usage 1. Local Government Manager get request to classify route 2. Set s up route in PBS RAT using mapping 3. Does an initial desk survey, gets initial result 4. May then do more detailed classification (s) a) Drive the route b) Use the route issues report c) Order engineering site inspections 5. Checks results and determines classification 6. Publish route (uploads) 7. Grants access (currently paper based)
