This research investigates the speed behaviour and safety effects on cyclists and mopeds sharing the cyclist T-Intersection with and without the application of a lane marking nudge. Unsignalised cyclist T-Intersection gives rise to more safety-critical instances, which include unsafe braking and evasive maneuvers. It is also found that uncontrolled T-intersection can create an issue when priority is assigned to the intersecting (right) arm because drivers on the straight road have a high perception of priority and fail-to-yield. Even though many studies have analysed the positive influence of the lane markings for cars, the influence of it on cyclists have not been explored. The safety criticality in this research is investigated using critical deceleration and jerk as Surrogate Safety Measures, because they are found to perform better at identifying potential conflicts compared to other time proximity measures, such as Time to Collision. Based on the results, the nudge did not show any strong evidence for reducing the speeds or safety criticality at the T-Intersection. So, it cannot be implemented as a traffic calming measure at the T-intersection without further research or modifications. So, this research also suggests key improvements with the lane marking nudge, and some crucial changes have to be implemented to avoid these kinds of unexpected outcomes in future. So, an elaborate discussion is made on what could be the possible changes with the implementation of the nudge for further investigations. Few intervention functions from the MINDSPACE framework and improvements from the behavioural change wheel have to be considered in the future researches with nudges.

With an increase in interest in putting people on bikes instead of driving vehicles for day-to-day transport, new regulations are being implemented to make roadways safer for cyclists while also encouraging cycling behavior among various segments of the population. The perception of safety has been proven to play a significant role in the decision to adopt active forms of transportation. The significance of this feeling is underlined even more when it comes to vulnerable road users, in this case, cycling children. This study seeks to provide a better knowledge of the road conditions that increase the perception of road safety in order to establish a safe and encouraging cycling environment for adolescents cycling to school. The preferences of different categories of the population toward various measures are explored using the stated preferences experiment. Furthermore, with the adoption of the new lowering of the speed limit policy, the attitude toward a growth in the usage of bicycles is done. According to the findings of this study, different sectors of the public have distinct perceptions and preferences toward the numerous aspects shown on the highways. The presence of separated bike lanes, a speed restriction of 30 km/h, and a priority for crossing rule for cyclists are discovered to be components that all groups in the sample strongly prefer. Parking on the country road is limited to the groupings of parents and road designers. Finally, the presence of speed displays is discovered to be negligible for all subgroups in the sample population as a measure that has no influence on making roads safer for children to cycle on. Furthermore, it has been discovered that parents who bring their children to schools that are now located near unsafe GOW50 roads have a more positive attitude toward cycling following the implementation of the speed limit policy. More aspects that were discussed in the GOW30 debate could be included in a future study to gain a better understanding of the impact of the various elements on providing a safe cycling environment for children. Furthermore, a recommendation is made to examine the behavior of parents in other locations that are also in close proximity to hazardous GOW50 roads and to incorporate the features of other respondents in order to corroborate the findings of this study.

Cycling has gained popularity worldwide, but little is known about the choice behaviour of people searching for a bicycle parking spot in the city centre. Formal parking spaces provided in the city centre are currently often underutilised, whilst many people use fly parking, which causes nuisance. This thesis aims to identify the most effective communication strategy to reduce the utilisation of fly parking and whether this differs for distinct user groups. Traffic signs were chosen as a means to present the different communication strategies. Information on choice behaviour was gathered with the use of a stated preference survey. Discrete choice modelling was used to analyse this data. The results show communication prohibiting the use of fly parking work very effectively in reducing fly parking. Interactions of socio-demographics and communication strategies were also found, indicating that belonging to a certain user group affects the effectiveness of the different communication strategies. What should be noted is that the effect of the interactions is marginal compared to the effect of the communication strategy itself. Meaning that the effectiveness of the communication strategy itself is most important. The research also tested how well traffic signs performed as a means of delivering the communication. It was concluded that solely showing traffic signs without providing any prior or other information is not very effective.

Deze scriptie beschrijft een onderzoek naar de toepasbaarheid van verschillende pop-up fietspaden. Dit zijn fietspaden welke in zeer korte tijd kunnen worden aangelegd en in een latere fase definitief worden gerealiseerd of weer verdwijnen uit het straatbeeld. Aangezien pop-up fietspaden in de meeste gevallen op dezelfde rij loper liggen als auto’s voorheen gebruikte is een rijbaanscheiding van belang. Eerst is onderzocht welke type pop-up fietspaden bestaan en hoe deze onderverdeeld kunnen worden. Voor dit onderzoek is gebruik gemaakt van een enquête welke is verspreid in Duitsland, Frankrijk en Nederland om de gebruikerservaringen van pop-up fietspaden te bepalen. Uit dit onderzoek blijkt dat Barrières afgezien van kosten erg goed scoren. Een parkeerstrook als rijbaan scheiding is een goede optie mits voldoende ruimte aanwezig is en de weg geen stroomweg is. Lijn markering zijn qua kosten voordelig maar moeten desondanks zo min mogelijk gebruikt worden. Net als bij normale fietspaden is de ligging van invloed op de veiligheid van fietsers. In verschillende landen hebben fietsers verschillende voorkeuren voor de ligging van een fietspad. Ook de regelgeving is verschillend hierover tussen verschillende regio’s. Uit dit onderzoek blijkt dat rijbaanscheidingen inwisselbaar zijn per type wegindeling. Om een keuze voor een optimale rijbaanscheiding te maken kan gebruik gemaakt worden van een keuze diagram op basis van snelheid van auto’s en beschikbare ruimte. Voor de wegindeling hebben alle types specifieke karakteristieken. Afhankelijk van de intensiteit lokaal of doorgaand fietsverkeer kan gekozen worden welk type wegindeling het beste bij de weg past aan de hand van een keuze diagram.

To intrigue more people to cycle, it is essential to assess the current design of the cycling infrastructure to guarantee the efficiency and safety for the users. A credible simulation of cyclists is helpful to evaluate different designs of infrastructure and point out the problem. A valid simulation model requires proper verification and validation. However, there was hitherto no standard procedure to conduct model verification, and limited studies were found related to the verification of cyclist simulation models. To fill this gap, this study develops a verification framework for traffic simulation models based on the methodologies used in the literature. It also briefly discusses the difference to verify a cyclist simulation model. The framework is assessed by applying to a case study of the cyclist-queue-formation simulation model. The results prove the applicability of the framework to verify a cyclist simulation model. The organised structure of the framework provides a systematic measure for the verification of traffic simulation models. Furthermore, the cyclist-queue-formation simulation model is verified within the study area, where its conceptual model is proposed. The room for improvement of the simulation model regarding the relatively slow correction behaviour in steering and pedalling of the cyclists was also indicated.

This studydives into factors influencing the shared e-moped usage in first- and last mile. Other studies show that the service area size, vehicle availability the shape of city and the temperature affect the shared e-moped usage. This study confirms the service catchment, temperature and vehicle availability factors. It adds to this that also factors such as the share of young people, bus frequency, shared bike availability, walking distance, visibility and points of interest have an influence. This study also provides a quantification to show which factor has the biggest influence. According to the model results, the vehicle availability at a station is the most important factor. Next to the factors, this study also shows what the usage patterns of shared e-mopeds in first- and last mile transportation are. This study, therefore, helps in understanding the usage of shared e-mopeds as a first- and last mile mode.
