ABSTRACT A Decision Support Tool to Identify Countermeasures for Pedestrian Safety by Madhuri Uddaraju Dr. Shashi Nambisan, Thesis Committee Chair Professor, Department of Civil and Environmental Engineering University of Nevada, Las Vegas Enhancing pedestrian safety and providing a pedestrian-friendly environment are key goals for urban planning and public works organizations. The primary tasks to be accomplished in enhancing pedestrian safety include identifying high pedestrian risk locations and implementing appropriate countermeasures to minimize the risks. The selection of such countermeasures to address specific pedestrian safety concerns should be done based on factors that influence the risks. A methodology to identify suitable countermeasures for various scenarios is developed in this research. The factors considered for selection are crash contributing factors, roadway functional class, posted speed limits, type of location (intersection/non-intersection), vulnerable age groups of pedestrians, and average daily traffic. A computerized decision support tool that helps the user to identify appropriate pedestrian safety countermeasures is developed. This tool is automated in Microsoft Excel environment using Visual Basic Applications. Ill Reproduced with permission of the copyright owner. Further reproduction prohibited without permission.

    DEVELOPMENT OF AN AGENT BASED SIMULATION MODEL FOR PEDESTRIAN INTERACTIONS by MOHAMED HUSSEIN B.Sc., Ain Shams University, 2004 M.Sc., Ain Shams University, 2010 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Civil Engineering) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) December 2016 © Mohamed Hussein, 2016 Abstract Developing a solid understanding of pedestrian behavior is important for promoting walking as an active mode of transportation and enhancing pedestrian safety. Computer simulation of pedestrian dynamics has gained recent interest as an important tool in analyzing pedestrian behavior in many applications. As such, this thesis presents the details of the development of a microscopic simulation model that is capable of modeling detailed pedestrian interactions. The model was developed based on the agent-based modeling approach, which outperforms other existing modeling approaches in accounting for the heterogeneity of the pedestrian population and considering the pedestrian intelligence. Key rules that control pedestrian interactions in the model were extracted from a detailed pedestrian behavior study that was conducted using an automated computer vision platform, developed at UBC. The model addressed both uni-directional and bi- directional pedestrian interactions. A comprehensive methodology for calibrating model parameters and validating its results was proposed in the thesis. Model parameters that could be measured from the data were directly calibrated from actual pedestrian trajectories, acquired by means of computer vision. Other parameters were indirectly calibrated using a Genetic Algorithm that aimed at minimizing the error between actual and simulated trajectories. The validation showed that the average error between actual and simulated trajectories was 0.35 meters.

  • Minneapolis Transportation Action Plan (Engagement Phase 3)
    Minneapolis Transportation Action Plan (Engagement Phase 3) Email Comment Topic Comment # The recommendations in this submission expand on this principle and support the overall Transportation Action Plan goals of designing transportation to achieve the aims of Minneapolis 2040, address climate change, reduce traffic fatalities and injuries, and improve racial and economic equity. In line with these goals, our most significant recommendations for the Prospect Park area are to • Invest in the protected bike network: extending the Greenway over the River, and building the Prospect Park Trail along railroad right-of- way • Transform University Avenue and Washington Avenues • Complete the Grand Rounds and use the Granary corridor to redirect truck traffic Priorities for transportation improvements in Prospect Park 1. Improve pedestrian infrastructure throughout the community including safe crossings of University Avenue SE (Bedford, Malcolm, 29th and 27th), Franklin Avenue SE (Bedford, Seymour) and 27th Avenue SE (Essex, Luxton Park to Huron pedestrian overpass). We encourage the city to narrow residential intersections, particularly in Bicycling, the Tower Hill sub-neighborhood where streets do not meet at right Walking, 1 angles, and crossing distances are significantly longer than needed. Additional Planters and plastic delineators could be used to achieve this ahead of Comments reconstruction. Maintenance and improvements should focus on public safety, adequate lighting and landscape upkeep. Throughout the neighborhood residents have cited safety (particularly at night), sidewalk disrepair, narrowness, snow and ice issues, and have expressed support for full ADA compliance. 2. Complete the Minneapolis Grand Rounds and the Granary Corridor (see Map 2) to enhance community access to city and regional parks and trails as well as to adjoining neighborhoods.

  • Pedestrian Scramble Crossings – a Tale of Two Cities
    Pedestrian Scramble Crossings – A Tale of Two Cities by Rajnath Bissessar, City of Toronto & Craig Tonder, City of Calgary ABSTRACT Pedestrian Scramble crossings (also called “exclusive pedestrian phase” or “pedestrian criss-cross”) have been used in a number of cities around the world to enhance the safety and mobility of pedestrians at signalized intersections. A dedicated phase for pedestrians allows them to cross in any direction, including diagonally, without coming into conflict with turning vehicles. In 2008, both Calgary and Toronto implemented pedestrian scramble phases at select downtown intersections. While pedestrian safety can be enhanced, other operational problems can arise, particularly for blind and visually impaired pedestrians who use guide dogs and/or the sound of traffic as cues to cross the intersection. This paper will outline the justification and analysis prepared in advance of the installations, along with the implementation process, including stakeholder consultation, design and education. The paper will also discuss the similarities and differences in the approaches adopted by Calgary and Toronto. Finally, the paper will discuss the findings from the evaluation studies completed for each project. 1 of 27 1. INTRODUCTION A pedestrian scramble phase is a traffic signal phase that provides pedestrians with exclusive access to a signalized intersection while vehicular traffic is stopped in all directions. This form of phasing is useful at intersections with heavy pedestrian traffic and vehicle turning volumes as it serves to reduce vehicle- pedestrian conflicts by providing exclusive phases for pedestrians, and sometimes, for motorists. A scramble phase is generally displayed as a red signal in all directions for vehicles in conjunction with the “Walk” display in all directions for pedestrians.

  • City of Los Angeles Inter-Departmental Memorandum
    CITY OF LOS ANGELES INTER-DEPARTMENTAL MEMORANDUM Date: November 19, 2018 To: Honorable City Council c/o City Clerk, Room 395 Attention: Committee Chair From: Seleta J. Reynolds,(ybneral Manager Department of Transportation Subject: Vision Zero Implementation Strategy for the Safety of the Traveling Public (CF 17-1137) SUMMARY This report addresses the Vision Zero prioritization methodology, proposes 20 new Priority Corridors and 60 Priority Intersections, and provides a status update on implementation of improvements on existing Priority Corridors. Per Council direction, the Los Angeles Department of Transportation (LADOT) re-evaluated how it prioritizes safety projects on the City's High Injury Network (HIN) and proposes a new model for identifying Priority Corridors. LADOT also proposes a list of Priority Intersections consisting intersections where a high number of people have died or been seriously injured across all modes (vehicle, motorcycle, bicycle, and pedestrian). RECOMMENDATION LADOT recommends the Los Angeles City Council: 1. APPROVE the Vision Zero prioritization methodology. 2. APPROVE the list of new Priority Corridor locations. (Attachment 1) 3. APPROVE the list of new Priority Intersections. (Attachment 2) 4. RECEIVE AND FILE the update on Priority Corridors from 2017. (Attachment 3) BACKGROUND In 2015, Mayor Garcetti signed Executive Directive 10 to establish a goal of zero traffic fatalities by 2025 and included a set of policies and programs to achieve this goal. Vision Zero included the development of the City's first High Injury Network, which identified the 6% of city streets that account for 70% of deaths and serious injuries for people walking. Honorable City Council 2 November 19, 2018 In January 2017, the City of Los Angeles identified 40 Priority Corridors, a subset of the High Injury Network, to focus its first round of safety improvements.

In order to analyze the effectiveness of setting exclusive pedestrian phase (EPP) under different vehicle yielding rates, the effect of EPPs on traffic efficiency is studied and a setting condition of EPP considering pedestrian-vehicle interaction is proposed in this paper. First, the main factors influencing the behavior of vehicles and pedestrians during pedestrian-vehicle interaction are analyzed, and a pedestrian-vehicle interaction (PVI) model at the crosswalk of urban road is established. Second, assuming that vehicle arrival obeys the Poisson distribution, the delay models of vehicle passengers and pedestrians crossing the street at the intersection are established, and taking the total delay of traffic participants as the main index, the setting condition of EPP are proposed. ,ird, based on the video of pedestrian-vehicle interaction at crosswalks, the parameters of the proposed model are calibrated. ,rough sensitivity analysis, the change of the total delay of traffic participants is analyzed under different conditions of pedestrian and vehicle arrival rates.

  • An Integrated Approach to Estimate Pedestrian Exposure to Roadside Vehicle Pollutants
    An Integrated Approach to Estimate Pedestrian Exposure to Roadside Vehicle Pollutants by Fangzhou Su A thesis submitted in conformity with the requirements for the degree of Master of Applied Sciences Department of Civil Engineering University of Toronto © Copyright by Fangzhou Su, 2014 ii An Integrated Approach to Estimate Pedestrian Exposure to Roadside Vehicle Pollutants Fangzhou Su Master of Applied Sciences Department of Civil Engineering University of Toronto 2014 Abstract At many urban intersections, pedestrians and vehicles share the same space, where interactions between pedestrians and vehicles may hinder vehicle turning movements. This changes the amount of emissions generated by the vehicles, to which the pedestrians are exposed. This research investigates the pedestrian-vehicle interaction at the intersection of St. George Street and College Street in downtown Toronto. A microscopic vehicle simulation is integrated with a microscopic pedestrian simulation. Emission generation and dispersion are modelled to obtain concentration maps for emitted pollutants. The spatial-temporal data of the pedestrians are then integrated into these concentration maps to calculate pedestrian exposure to vehicle pollutants. Lastly, this framework is applied to test the effects of implementing a scramble signalling system at the intersection of St. George Street and College Street. It is found that the implementation of a scramble phase would increase exposure to Nitrogen Oxides and decrease exposure to Carbon Monoxide. ii iii Acknowledgements Writing the thesis acknowledgement feels good, because it means the hard work of actually producing the thesis is complete. Looking back through the last 20 months, I realize that my research would not be the same without the support I’ve received from all of these people.
