Local Arrangements, Liaison and consultation

Road Safety Officers (RSO)

• Involved in Education, training and publicity programmes, to try and change road users behaviour – long term benefits
• School based – inform and advise teachers
• Safety planned to compliment other national curriculum topics
• Training Programmes – aimed at specific types of road users – develop practical road use skills
• Publicity Campaigns – Media/leaflets/advertising

Road Safety Engineers (RSE)

• Responsible for making the road network as safe as possible, to reduce number and severity of casualties
• Involves physical changes to the network – mainly light.
• Effects all road users that travel through the scheme

Road Planning Officers

• Take account of road safety and planning
• Liaise with both RSO’s and RSE’s

Road Safety Qualifications


• RoSPA
• BITER
• TMS
• PTRC


General Principals

A local transport plan is a statutory document produced by a local authority. It sets out a five year integrated transport strategy devised in partnership with the community. The local transport plan covers every transport related activity carried out by the local authority. Two recently published documents give guidance on developing full LTPs and examples of good practice LTP development.




Survey Techniques

• Revealed Preference/Stated Preference
• Traffic Component Assessment
• Personal/Qualitative Response


OSGR – Ordinance Survey Grid References



Design Process Requirements

• Current State of transport system and how it has changed.
• Alternative design standards and implications on scheme proposals
• Predictions of effects the scheme will have
• How it will effect the community


Road Networks

• Common - traffic related data – referenced over the road network, which can be specified as links (sections of motorway with different characteristics).
• NODES – Junctions or points where changes in link characteristics occur.

• Nodes – given reference number (OSGR location). Links are then specified by the numbers of the nodes at each end.

• The network codes can then be used to store information relating to highway characteristics – traffic flows – maintenance records.

GIS – Geographic Information Systems

• Computerised map in which various database information can be held/displayed/manipulated/reported.
• Locational referencing carried out using OSGR
• GIS might be used in connection with a traffic count database, which covers a large amount of roads and contains comprehensive historical records.

Used for -

• Identifying traffic count locations and nature/quality of data available
• Highlight particular location(s) to provide access to the raw data
• To manipulate the raw data to provide, average daily traffic flow levels, heavy goods vehicle content and year – on – year traffic growth trends

There is Software available that combines GIS and CAD.

National Inventory Data

DfT holds a large amount of data, collected in scheme appraisals




Accident Rates

• Potential Accident Reduction – PAR
• PAR – Designed to estimate the number of accidents expected at a particular site (according to layout and prevailing traffic conditions)
• STATS 19
• Accident Causation factors are not recorded on the STATS 19 form – not always related to the limited number of physical features (which are recorded).

Severity Ratio

Severity Ratio(SR) = Number or fatal of serious accidents per year
Total number of injury accidents per year

Will be influenced by –

- Protective attitude of the occupants of the vehicles.
- Road Environment
- Traffic Level

Processing Accident Data

•  Accident Data records contain the main details from a STATS 19 form.
• Four basic Functions within GIS
- Assignment of each node, link, cell or road section on the road network, as defined within an authority’s representation of the road.
- Extractions of tables showing trends in accidents for the area as a whole.
- Plotting of the distribution of all the accidents over the network(reveals hot spots, accident clusters)
- Cluster analysis.
