3. PROBLEM DESCRIPTION

Modern roundabouts have been gaining popularity in the United States in the past decade due to the safety benefits as well as other positive impacts (such as reduction in delay) that they bring to the communities. The safety benefits are contributed by the geometric design of the entry approach and circulatory roadway, which reduce vehicle speed and shifting right-angle crashes to angle or sideswipe collisions. A new variant of the modern roundabout, known as the turbo roundabout, has potential to further reduce angle and sideswipe crashes. Turbo roundabouts are so far only in operation in Europe. No turbo roundabout has been constructed in the United States. Since the turbo roundabout is a recent innovation, the design guidelines are very limited. Additional research efforts are necessary to understand the safety benefits and operational implications prior to developing design recommendations, both of which consider the behavior of all type of users in the United States. State and local transportation agencies are in need of guidelines to determine intersections that are potential implementation sites so as to prioritize turbo roundabout implementation projects.

4. BACKGROUND SUMMARY

Modern roundabouts began in the United Kingdom and spread to France and Norway in the 1970’s. In the United States, the first modern roundabout was constructed in Summerlin, Nevada in 1990; and since then, around 100 more roundabouts have been constructed in Nevada, and more than 8,400 nationwide (Kittelson, 2020). After the implementation of roundabouts in the United States, the number of fatalities and serious injuries resulting from intersection-related crashes have reduced significantly. Still, more than one-third of all crashes, fatalities, and serious injuries occurred at intersections. The Fatality Analysis Reporting System (NHTSA, 2020) reported a total of 104 fatalities that occurred at intersections in Nevada in 2019. Modern roundabouts are known to be safer than stop-control and signalized intersections. Single- lane modern roundabouts have limited capacity. Multilane modern roundabouts, which provide higher capacity, create issues such as higher speed, more conflict points compared to single-lane modern roundabouts, and allowing lane changing in the roundabout, which all contribute to the risk of crashes. Fortuijn (2009a) addressed those issues by limiting lane changing in the circulatory roadway and removing the need for entering vehicles to yield to traffic on the far side of the circulatory lane (i.e., the inner lane). Turbo roundabouts were first built in 2000 in the Netherlands. This was followed by their adoptions in Poland, Germany, and other European countries. There have been 603 turbo roundabouts in operation in Europe (DeBaan, 2020). There are different types and design features of turbo roundabouts: (i) basic; (ii) egg; (iii) knee; (iv) spiral; and (v) rotor (FHWA, 2020). They differ in capacity and number of approach lanes. A diagram of a basic turbo roundabout is

1 presented in Figure 1. Dabiri et al. (2020) studied the effect of geometric characteristics on operational performances of the turbo roundabouts and found that basic turbo roundabouts have smaller delay, higher capacity, and better level of service compared to rotor turbo roundabouts. Safety is the main benefit of the turbo roundabout. It is basically explained by the reduction of number and type of conflict points. In turbo roundabouts, the reduction of conflict points varies between 38% – 66%. Compared to a typical multilane (two-lane) roundabout, a turbo roundabout reduces the number of potential conflict points from 16 to 10 (Fortuijn, 2009a). The study reported that, when seven intersections in the Netherlands were converted into turbo roundabouts, the reduction in crash rate was 76.1%. In a more recent simulation study, Mauro et al. (2015) found that the number of total potential crashes was reduced by up to 50% and the number of accidents with injuries was Figure 1. Basic turbo roundabout. decreased by up to 30%. Other studies in Source: FHWA (2020). Europe (Macioszek, 2015), which all compared turbo roundabouts with other types of intersections found that turbo roundabouts are the safest option, which provided 30% to 60% reduction in crashes, 40% to 90% reduction in injuries, and 70% to 95% reduction in fatalities.

Another factor that contributes to the safety benefits of turbo roundabouts is the lane dividers. The turbo roundabouts with raised lane dividers have fewer sideswipe crashes than the turbo roundabouts with regular pavement markings (Macioszek, 2015). The choices of circulatory lane dividers differ in different European countries. Macioszek (2015) showed that the drivers in turbo roundabouts in Poland without raised lane dividers continued illegal lane changes, while the turbo roundabouts with raised lane dividers were safer. Chodur and Bak (2016) conducted another study in Poland and showed that raised lane dividers reduced the number of crashes between 10% to 17% compared to the regular pavement markings. Besides the safety benefits, another advantage of the turbo roundabout is the ability to handle higher capacity and allow equal entry lane utilization. Drivers approaching a turbo roundabout are expected to decide on their lane choices before entering the roundabout and then keep to the same lane until they exit the turbo roundabout. Therefore, unlike the multilane modern roundabouts, which generally have an underutilized inner circulatory lane, turbo roundabouts promote equal utilization of the entry lanes at the same approach and the circulatory lanes (Homola and Chan, 2014). European studies revealed that the entry capacity of a turbo roundabout is 25% to 35% higher than a multilane modern roundabout (Fortuijn, 2009b). However, as stated by FHWA (2020), the roundabout capacity in Europe is likely to be higher than in the United States mainly because of the driver familiarity with roundabouts. Although some European researchers (Brilon et al., 2014) recommended turbo roundabouts only in suburban areas or in urbanized areas without cyclists and pedestrians, FHWA (2020) reserved

2 a subsection for all type of potential users of turbo roundabouts including motorists, pedestrians, cyclists, and motorcyclists. Generally, the footprint of a turbo roundabout covers a smaller area than a multilane modern roundabout of the same number of lanes because of nesting the spiral lanes to the inner side of the roundabout. This benefit is important especially in densely urbanized areas with limited space and right-of-way (Fortuijn, 2009a). Internationally, the entry radii of the turbo roundabouts vary between 39 to 50 ft, whereas the multilane modern roundabouts in the United States are designed with entry radii between 50 to 100 ft (Rodergerdts et al., 2010). Roundabouts should always be designed for the largest vehicle (i.e., the design vehicle). Since heavy vehicles occupy a greater area when executing their turning movements, the European design standards should be updated to accommodate the larger vehicle sizes in the United States (Rodegerdts et al, 2010).

5. PROPOSED RESEARCH

The objective of this research is to investigate the implementation potentials of turbo roundabouts in Nevada through evaluations of applicable conditions, safety benefits, operational performances and costs. This project will be carried out over 12 months. The research team will: (1) Review the current usage of turbo roundabouts, particularly in the Netherlands; (2) Collect intersection data in Nevada; (3) Develop Turbo roundabout Implementation Metric (TIM), with feedback provided by NDOT engineers, in the form of a worksheet for identification and ranking of suitable intersections for turbo roundabout implementation; (4) Develop Turbo roundabout Implementation tool for NevadA (TINA), a user-friendly plug- and-play interactive software application that runs on Microsoft Excel for NDOT to implement TIM with ease; (5) Apply TINA to selected intersections of interest in Nevada; and (6) Develop multilingual, easy-to-understand outreach material for NDOT to use on educating the public and K-12 on turbo roundabouts. A more detailed description of each task, including deliverables, is described below: 1. Literature and Technology Review. [Months 1-2] In this task, the research team will review existing literature and websites related to turbo roundabouts, including FHWA (2020). This task also involves telephone, email, and/or Zoom interviews with several experts in the field, primarily among the members of the TRB Standing Committee on Roundabouts (AKD80). At the end of the interviews, the research team will identify the preliminary decision factors that are important for the implementation of turbo roundabouts, and for each decision factor, determine the numerical measures. An infographic flyer introducing turbo roundabouts, the features and benefits will be developed. Expected deliverables: An interim literature review report. Preliminary decision factors and measures. Infographics flyer. 2. Data Collection. [Months 3-4] The research team will work with the Project Champions to collect existing, readily available intersection data in Nevada for subsequent evaluation of turbo roundabout potential. The requested data attributes will include the decision factors and measures proposed at the end of Task 1. The research team will not perform on-site data collection. The use of only existing

3

data enables NDOT to evaluate intersections without additional time and cost. Possible sources of data are the National Performance Management Research Data Set (NPMRDS) Analytics Tool for Nevada and/or NDOT’s Crash Data dashboard. The data provided by NDOT will be organized in electronic form in a suitable format, e.g., Microsoft Excel worksheets. The decision factors and measures will be revised to keep only those for which data is available to conduct evaluation. Expected deliverables: List of intersections and their available data. Revised list of decision factors and measures. 3. Development of an Implementation Metric. [Months 4-6] In this task, the research team will develop TIM based on the revised decision factors and measures obtained in Task 2. A mock-up of TIM is shown in Table 1. Table 1. Mock-up of TIM.

Total Credit Points =

The PI will conduct an online anonymous survey of NDOT engineers using UT Tyler’s Qualtrics Survey tool. The survey will ask a series of questions to identify the relative

4

weights (called “Credits” in TIM) of the decision factors and their associated measures. The PI will obtain proper Qualtrics certification and Institutional Review Board (IRB) approval with UT Tyler prior to the online survey. The survey results will help the research team to fine-tune the decision factors and measures and assign them proper credits. As can be seen in Table 1, each decision factor has one or several measures. Each measure will earn 1 to 4 points depending on the site condition. The points earned is then multiplied by a credit. The final output of TIM is the total credit points of a site. This value may be used by NDOT to rank the intersection. As part of the outputs, TIM will also recommend the type(s) of turbo roundabout suitable for implementation. After the initial form of TIM has been proposed, the research team will use data from several intersections collected in Task 2 to validate the metric. Expected deliverables: TIM. Online survey results. Validation report. 4. Development of TINA. [Months 7-8] In this task, the research team will develop TINA, a user-friendly interactive software tool, which will be in the form of a Microsoft Excel Add-In for NDOT. TINA is the software version of TIM that comes with an intuitive graphical user interface. A mock-up of the interface is shown in Figure 2.

Figure 2. Mock-up of TINA user interface.

With TINA, NDOT engineers simply need to input the intersection-specific data related to the decision factors and measures in the left panel of the screen. TINA will automatically calculate the total credit points. Multiple intersections will be sorted and ranked according to the total credit points. Finally, for each ranked intersection, the recommended types of turbo roundabout will be listed on the right panel of the screen. Although TINA will be designed as a plug-and-play tool with a minimal learning curve, the research team will still provide a short training video on how to use TINA. Expected deliverables: TINA software tool accompanied by a short instructional video. 5. Case Studies. [Months 9-10] In this task, the research team will use TINA to evaluate the intersections for which the data have already been collected in Task 2. Expected deliverables: Ranked list of intersections according to the potentials of turbo roundabout implementation. 6. Report Writing and Preparation of Multilingual Outreach Material. [Months 11-12] The research team will finalize all work performed, which will be documented into a written report. Outreach material will be developed following the FHWA public involvement and educational approach with a focus on safety (FHWA 2020). The draft final report will be delivered to the Project Champions for comment before revising into the final form for NDOT. The outreach material will include color flyers, video clips for social media, and presentation slides for NDOT. They will be available in simple English and Spanish and delivered in electronic format. Expected deliverables: Final project report. Outreach material.

6. URGENCY AND ANTICIPATED BENEFITS

From a safety perspective, there were a reported 104 fatalities at intersections in Nevada in 2019 (NHTSA, 2020). Based on European studies thus far by Macioszek (2015), intersections after conversion into turbo roundabout have led to reductions of 70% - 95% in fatalities. If all such intersections in Nevada are converted to turbo roundabouts, these fatalities could be decreased to approximately 5 to 32 fatalities per year. This is a major step towards Nevada’s goal towards Zero Fatalities. Other benefits that come with higher entry capacity include reductions in delay and emissions.

7. IMPLEMENTATION PLAN

According to the Five Stages of Research Deployment provided along with the solicitation, this research project falls under Stage 4: First Application (Contract) Field Pilot Stage. The case study will apply TIM and TINA at real-world intersections in Nevada. At the completion of this project, NDOT will have the following tools for immediate implementation: (i) TIM; (ii) TINA; and (iii) outreach material. Each will be described below: i. TIM is a metric (a simple worksheet, see Table 1) for evaluation of the potential of converting an intersection to a turbo roundabout. TIM will be delivered in a PDF file for NDOT to mass distribute to engineers in all its districts. Users who do not want to use TINA (described below) have the option to use TIM.

6 ii. TINA is a user-friendly and intuitive software tool that automatically implements TIM in Windows 10 and iOS computers. TINA will be delivered as a Microsoft Excel Add-In; therefore, there is no need to purchase any additional software or equipment, and the Add-In may be freely distributed to all NDOT districts statewide for immediate, no-cost implementation. The accompanying instructional video will provide a free, on-demand tutorial that will help NDOT engineers to use TINA. iii. The outreach material will be delivered in English and Spanish in easy-to-understand language. The material will be in the form of: (i) infographic flyers on turbo roundabout features; (ii) 5- minute informational video on turbo roundabouts; and (iii) presentation slides on turbo roundabouts. The videos will be delivered in MP4 files. The infographic flyers will be in PDF files. The slides will be in PowerPoint PPTX files. They will be provided electronically so that they may be disseminated to the NDOT website, NDOT social media accounts, YouTube channel, TV channels, and other agencies immediately at no cost. They are useful material for NDOT to conduct public meetings and for K-12 outreach.

8. PROJECT SCHEDULE

The project will be carried out over 12 months. There will be five formal project meetings ( to M5). These five meetings are necessary and critical for the research team to report task accomplishments and to seek feedback on the products before proceeding to the subsequent tasks.
