Background of the 1995 E Road CensusRecommendati
ons to Governments (i)

• Coverage of the Census
• Purpose of the Census
• Scope of the census
• Comparability with the results of the 1990 Census
• Categories of vehicles to be counted
• Values to be calculated
• Design of the counts
• Characteristics of E roads
• Preparation and publication of 1995 Census data

3
1995 E Road Census Preparation and publication
of data Recommendations to Governments(ii)

• Characteristics of E roads (Tables Nos. 1 2)
• Number and nature of counting posts
  (Table No. 3)
• Distribution of motor traffic by vehicle
  categories. Total, night, holiday peak hour
  traffic (Tables Nos. 4 4B)
• Length and usage of roads (Table No. 5)
• 1995 Motor traffic density data at counting posts
  on E roads (Table No.7 and maps)

4
1995 E Road Census Recommendations concerning
Traffic Density Maps(iii)

• Counting posts to be shown on the maps.
• Scale
• Representation of Average Annual Daily Traffic
  (traffic buffers width and interval classes)
• Representation of E Road categories (motorways,
  express roads and normal roads)
• E Road and counting posts numbers
• Names of important towns and localities

What is a GIS?

• GIS is an electronic tool designed for capturing,
  storing, analyzing and presenting geocoded
  information (geographic, social, economic,
  political, transport, environmental, etc.)
• GIS uses the computer to pose and answer
  geographic questions by arranging and displaying
  data about places on the planet in a variety of
  ways, such as maps, charts and tables.
• GIS is the modern extension of the ancient
  mapmaking tradition.

Automation and Geographic application of 1995
Census

• Previous Census
• - Manually input data
• - Maps created using basic graphics software

8
Automation and Geographic application of 1995
Census

• 1995 Census (GIS context) 1/2
• In GIS all data are digitally geo-referenced
• facilitating
• the process of updating and harmonization of
  Census data
• the geographical analysis and display of the
  different Census data (tables, charts and maps)
• allowing for
• a faster publication of the E Road Census (even
  faster for the 2000 Census)
• a more sophisticated presentation of data and
  maps (improvement of statistical reports and
  cartographic production)

9
Automation and Geographic application of 1995
Census

• 1995 Census (GIS context) 2/2
• GIS is incremental
• It can always be feeded with new geocoded
  information, thus allowing for newer and deeper
  analyses.
• For instance, the Inventory of Main Standards and
  Parameters of the E Road Network can be easily
  intregrated into the GIS database developed for
  the Traffic Census.
• Variables like design speed or average width of
  either traffic lanes, central reserves or
  emergency stopping strips will be charted and
  mapped in a very straightfoward way.

10
Other benefits for UN/ECE

• The initiation of GIS capabilities at the PC
  level within UN/ECE by using ArcView software in
  order to visualize and study all the information
  contained in the GIS.
• The project will allow the electronic
  distribution of graphic and alphanumerical data
  (CD Rom)
• It is also forecasted to incorporate the GIS
  produced items on the Census, such as maps,
  statistical databases and reports into the
  UN/ECEs Web in the Internet.

11
Samples of GIS Analysis using ArcView software

• Visualizing Counting Posts on E Roads.
• Map making Density of Motor Traffic represented
  as a width.
• Interactive display of an E Road.

The different ways to read the european traffic
maps.

• Traffic maps reflect the orography and the
  political and administrative organization of
  european countries.
• 3 case studies the old inter-state frontiers,

The different ways to read the european traffic
maps.

• Summary
• The European Traffic Maps are useful
• to understand a complex reality European
  mobility.
• to improve the orientation of transportation
  plans and projects.
• to give an objective basis to define priorities
  and assign European budgets to them.
