Conclusions
A1: What will be the main factors limiting car accessibility in 2025?
Goal of this research has been to find measures that can be implemented to improve the car accessibility to the city center of Nijmegen from the north. The main factors limiting this car accessibility in 2025 are that the main route to the city center, south and east from the North will still be over the Waalbrug. Although planned measures (like the Stadsbrug and the widening of the A50), traffic loads on the Waalbrug will remain high and congestion will continue to occur. Other developments that play a role in this are the autonomous growth (car ownership, economic development) and the development of the Waalsprong, a large residential area (11.000 houses) just north of the Waal. Another factor is that alternative modes for car travel are not competitive with the travel time by car. Therefore, people will continue to take the car to go to the city center. This results in high traffic loads on the Waalbrug route which does not have enough capacity to handle the demand. The Keizer Traianusplein is the bottleneck in the system, but also growth possibilities on the Waalbrug are small.
A2: Which time periods and network user groups will be affected the
most?
The peak periods are the most busiest, this indicates home-work traffic. Also, the evening peak is busier than the morning peak. This indicates that in this period also people with different purpose mix in (e.g. shopping).

A5: According to which criteria will possible measures be evaluated?
From the interests of the main stakeholders the issues accessibility, livability and costs are found most important. Accessibility has been measured in XXXX/XXX*XXXX and travel time reliability.Livability was subdivided in air quality, noise and traffic safety which are the aspects of livability that are affected the most by car traffic. Costs are important as the problem owner is most likely the one paying for them.
S1: What measures could improve car accessibility?
A brainstorm session resulted in a list with possible measures to improve car accessibility. For this and this and that reason some of them were discarded which resulted in shortlist with viable alternatives.
S2: What are viable measures?
Three measures were found viable: an infrastructural measure that includes a redesign of the Keizer Traianusplein and the implementation of extra lanes on the Waalbrug to create more capacity. Also, a measure consisting of Waalsprinter improvements was found viable. Improvements include comfort, this that waiting shit.
Finally, a new parking policy was generated containing a renewed parking information system, signs and pricing policy.
M1: What is the performance of each viable measure?
Of the measures, the infrastructural measure performs best on the primary criterion of accessibility. An overall average decrease of 2,5% in generalized travel cost Is expected if this measure is being implemented. The Waalsprinter measure achieves a decrease of 0,4% in generalized travel cost and the parking policy is expected to decrease this cost by 0,2%.
On the livability criteria, all alternatives have mostly marginal effect. Noise and air quality levels are hardly affected by the measures. Traffic safety does improve in case of the infrastructural measure where conflicts are being reduced as a result of a multi-level crossing on the Traianusplein. Other measures do not have significant effect on traffic safety.
