Contribution of public transport to urban accessibility in the Netherlands
1. Contribution of public transport to
urban accessibility in the Netherlands
Ambrosius Baanders
ECORYS, Rotterdam
Paul van Beek & Sander van der Eijk
Goudappel Coffeng, Deventer
4. increasing congestion
decreasing accessibility of economic centres
Q: What is the present role of public transport
in serving the important economic centres
and how can public transport help to alleviate
car congestion problems?
5. study commissioned by NL Ministry of Transport
to ECORYS and Goudappel Coffeng
objective:
make “photo” of current contribution
of PT
estimate potential to increase
contribution of PT
7. method [2]
preliminary choices:
current situation transport model base years
morning peak: 07:00 – 09:00
twelve regions
focus on “economic centres” in urban areas
trips relevant for public transport

and relevant trips
100%
Total number of arrivals per region
50-80%
Dispersed trips
(not linked to the cities) Arrivals in the cities
20-50%
Arrivals outside the Arrivals in the
Economic Centres Economic Centres

Trips of < 2,5 km Arrivals relevant for

Estimation of potential
15. method [3]
workshops:
participants: experts from local / regional
stakeholders
making estimates of effects with the help of
an interactive spreadsheet
16. method [3]
steps in the workshops:
1. verify the data
2. select the measures (“policy dials”)
3. estimate the potential growth relative to current PT volume
4. feedback on the results
17. method [3]
number of trips >100
Origins of morning peak trips to 23 % share PT
Utrecht Centre-North
19. method [3]
steps in the workshops:
1. verify the data
2. select the measures (“policy dials”)
3. estimate the potential growth relative to current PT volume
4. feedback on the results
20. The “policy dials”
• Quality of public transport
• Parking policy
• Public transport fares
• Mobility management
• Intermodal chaining
• Marketing and image
23. method [3]
steps in the workshops:
1. verify the data
2. select the measures (“policy dials”)
3. estimate the potential growth relative to current PT volume
4. feedback on the results
24. method [3]
steps in the workshops:
1. verify the data
2. select the measures (“policy dials”)
3. estimate the potential growth relative to current PT volume
4. feedback on the results
28. results: the “photo”
level of the regions
90 – 50 % of trips have destination in urban area
all modes:
work trips 50 – 58 %
education trips 22 – 26 %
other trips 20 – 23 %
public transport:
work trips 56 – 53 %, large cities ~ 62 %
education trips 43 – 44 %, large cities ~ 33%
other trips 3– 5%

34. conclusions
current contribution
What is current role?
Flows within the cities / urban areas
Flows from other regions
What is explanation of differences?
Differences in local circumstances
Influence of land use patterns?
Role increases with size of the urban area
Which travel purposes?
Work = 50%+, education = 50%-.
Largest cities: work = larger share
35. conclusions
estimation of the potential
What is expected potential?
Between 1 % and 10 % of total trips to economic centres
Increase at the expense of which mode?
The car (bicycle > 2.5 km?)
What measures contribute?
Improvement of PT supply quality
Makes tightening of parking regime possible
Mobility management, intermodal chaining, marketing
Fares not important
Relationship between the measures?
“Dials” cannot be turned independently “Tuning”
Role of the train?
larger in largest cities
varies elsewhere due to local network configuration
36. conclusions
the method: combining models and expert
knowledge
Worked well
Was a combination of several benefits:
models used that were owned by the regions = own tools
expertise in the regions used: clear added value to model results
outcomes were trusted, because not a black box
