Evaluate the Quality of the Biking Environment Based on Large-scale Analysis of Google Street View Images
My research aims to establish a methodology to evaluate the biking environment of city streets by conducting image segmentation on Google street view photos. The research will especially focus on identifying a set of better indicators from the segmentation results that can be the index of evaluating the biking environment for safety, and improve the accuracy of the evaluating method.
I'm feeling very lucky to be selected as a CSCRS fellow because this is the first time that my research interest is valued by other people. I'm very excited to start a whole new journey here with all the other fellows.

Impact of a Traffic Light Failure on the Risk of Crashes at Intersections
The road network can be disrupted by various causes. A power outage deactivating signal lights is just one example of the many potential causes of massive road network disruptions. Other causes include natural disasters (earthquakes, hurricanes, etc.), or even cyber attacks. The impact of these extreme events has a significant impact on road safety and the goal of my project will be to quantify it.
I am honored to have been selected as a CSCRS Fellow. This award, by providing me with resources and mentoring, will allow me to contribute to this exciting field of research.

Examining Associations Between Human-Scale Streetscapes and Perceived Safety Among Pedestrians
Perceived safety is an important criterion for pedestrians deciding where, or even whether, to walk. My research examines how streetscape design influences safety perceptions using a combination of physiological stress indicators, participant photography, and semi-structured interviews to examine how participants react to diverse streetscapes. Results will inform how streetscape design may be used as a lever to promote perceived safety and encourage pedestrian transportation.
It is exciting to play a role in expanding conversations about the role of perceived safety in transportation behavior, and about how factors outside the traditional realm of transportation, such as streetscape design, can be incorporated into the transportation safety toolkit.

Formalization of Scenario Description via Probabilistic Programming Language
Scenario generation in simulation for autonomous vehicles is an uncharted territory and an urgent issue for road safety. My project will focus on developing a dynamic scenario (i.e. includes actions of traffic participants) description programming language that puts forth a groundwork for a systematic approach to simulation by formalizing the way scenario is described (syntax) and understood (semantics). Using the proposed language, we can abstract away from low-level reasoning on waypoints and trajectories, and reason at an intuitive high-level of understanding. We envision scenario description as a program that can be automatically compiled down to a machine readable code and be executed/simulated across different simulators.
I am excited to work on this innovative research direction and have a chance to share it with researchers in the CSCRS. I believe there is a strong connection between my proposed research and various CSCRS's research projects on safe systems, such as the work being done to link crash and post-crash data.

Putting a Price on Truck Parking: A Planning & Public Health Policy Perspective
My research aims to analyze the relationship between limited freight truck parking and operator-involved, fatigue-related collisions along one of the busiest freight corridors in the state, California’s Interstate 5 (I-5). Previous studies have not deeply explored how paid parking and market-based, demand-responsive pricing could be used as a regulatory tool to help reduce collisions and improve safety outcomes along highway systems. This study will conduct a state-level policy and equity analysis regarding the feasibility of implementing demand-responsive pricing for truck parking at Caltrans’s public rest stops.
I am deeply honored to have been selected as a CSCRS Fellow. Through the support of the fellowship and SafeTREC, I look forward to contributing to research that improves safety outcomes for truck drivers and for those sharing the road with them.

Evaluating the Effects of a Bicycle Education Intervention on Mode Shift, Confidence and Riding Frequency
Bicycle safety education is implemented in numerous cities as a strategy to increase the number of people traveling by bicycle. However, little is known about the effects of bicycle education on rider outcomes such as mode shift, confidence and rider frequency. This study surveys bicycle education participants to find out more about the effects of the class intervention.

Understanding the Birth of Our Modern Traffic Order, 1896-1960
My research aims at building a global history of the basic norms, rules, and assumptions which underpin our relationship to motorized movement on the open road. It is my hope that by understanding the social and political forces that brought these assumptions into being, road-safety practitioners will be better able to imagine new ways of working with, against, and around them. Moreover, I believe that studying how societies in the past adapted themselves to the automobile will help our own society prepare itself, institutionally and emotionally, for the coming of autonomous vehicles.
With this fellowship, CSCRS has given me something that historians hardly ever get: the chance to be in direct conversation with people whose work affects daily life in an immediate and material way. To be given an opportunity to show how history can contribute to such work is, for me, both a privilege and a real, sincere pleasure.

The Impact of Dynamic Speed Limits on Road Safety
Except in some rare experiments, speed limits have so far mostly been static. Dynamic or Adaptive speed limit is the art of making the speed limits varying, depending on the weather, traffic and visibility conditions. The goal of my research project is to select the most relevant parameters, to build a dynamic speed limit model and to predict the effect of the introduction of such a dynamic speed limit model on road safety.
Being selected as a CSCRS Fellow is a great honor. I am looking forward to working with Berkeley SafeTREC's team and to exploring the possibilities offered by combining the power of data and mathematical optimization to make roads a safer place!
