This paper proposes a deep reinforcement learning-based driving strategy for individual vehicles to mitigate oscillations and optimize traffic safety in stop-and-go waves on federal highways. A deep deterministic policy gradient (DDPG)-based driving strategy, which requires information that is directly obtained by in-vehicle sensors, is proposed for system performance optimization. Two typical scenarios were simulated based on simulation software (SUMO): (i) the leading vehicle slowed down according to real trajectory data to produce one oscillation; (ii) the leading vehicle conducted several abrupt decelerations with various degrees of disturbance to produce multiple oscillations. Results showed the proposed strategy outperformed other oscillation mitigating strategies in reducing crash risks.

This study conducts an exploratory analysis to understand the inter-relationships between highway system reliability, freight, and traffic congestion in light of the federal rulemaking that establishes these performance measures. To do this, several traffic and roadway related characteristics of each reporting segment of the National Highway System (NHS) of South Carolina were processed and modeled for the travel time reliability and peak hour excessive delay using generalized linear models with a log-link function. The results from the study indicate that the unreliable Interstate segments contributed to about 87% of the excessive delays on the entire Interstate.

The city of San Francisco has a Vision Zero goal to end traffic violence deaths by 2024. Since they are not currently on track to meet this goal, they are looking for new solutions on how to reduce traffic fatalities. Some of the solutions they are looking at are installing more red light cameras, which are intended to mitigate the roughly 9 percent of injury crashes that result from speeding through stoplights; developing a roadmap-style dashboard to track progress; and collaborating with other partners to improve enforcement, education and outreach on street-safe behavior.

This paper tracks the history of fighting traffic congestion in Los Angeles (LA). The paper describes the ways in which city officials, Southern California Association of Governments, and Metro have tried to solve the congestion solution since 1920. The many solutions proposed for solving traffic congestion include public transit, encouraging people to move out to suburbs, building ever wider freeways, inventing traffic management regulations and technological fixes but these solutions have not helped the growing congestion in LA.

This paper assesses how “aerodynamic damping” can be an active means to mitigate the large amplitude vibrations of cantilevered-arm traffic structures (e.g. structural supports of signs, luminaires, and traffic signals) caused by a windy weather environment. The proposed method uses the inherent characteristics of the traffic light (specific dimension ratios) to ensure that the aerodynamic damping is maximized during the gust events. The tests that were conducted in the Wind Simulation and Testing (WiST) Laboratory have shown that the proposed approach will help improve the performance of traffic signal structures.

This paper assesses the California Department of Transportation (Caltrans)'s use of continuously reinforced concrete pavement (CRCP) as the preferred pavement type for high-volume truck corridors across the state. This project included a review of national CRCP practice, documentation of Caltrans’ statewide practice, and condition assessment of select CRCP projects statewide. For the most part, Caltrans’ CRCP practice is similar to national guidance and other state highway agency practice but a condition assessment of 14 CRCP projects revealed a wide range of performance with various degrees of distresses (i.e., transverse, cluster, and Y-cracking, and punchouts). Results from this study will be used to provide recommendations to advance Caltrans’ CRCP practice.

This paper explores the relationship between freight-haul growth and large truck-related crashes. In this study, the project team applied taxicab correspondence analysis (TCA), a data-mining method known for dimension reduction, to large truck fatal crash data to investigate the complex interaction between multiple factors under a two-dimensional map. The study found five clusters of attributes that show patterns of association between different crash attributes such as two-lane undivided roadways, intersection types, posted speed limit, crash types, number of vehicles, driver impairment, and weather.

The city of Pheonix, Arizona has installed new traffic light technology at intersections in central Pheonix as part of a pilot program within the city to improve traffic flow and reduce vehicle and pedestrian delays based on demand. The smart traffic light technology, which was created by California-based NoTraffic, autonomously operates traffic light grids to allow smooth and efficient traffic flow. The technology uses software identification that can distinguish between different modes of transportation and can reduce the time vehicles and pedestrians sit waiting at traffic lights. It can also enable different services, including emergency vehicle preemption, transit signal priority, and pedestrian prioritization.

The paper describes a study conducted with a platoon of five vehicles with different vehicle type combinations in various scenarios The study found that adopting the CACC system in a five-vehicle platoon reduces driving volatility, the risk of rear-end collisions, and fuel consumption compared with the ACC system and manually-driven vehicles in some scenarios. On the other hand, results of the a merging traffic scenario show that while the cooperative merging system slightly reduces the driving volatility, the fuel consumption and emissions can increase because of sharper accelerations of CACC vehicles compared with manually-driven vehicles.

This research explores the pseudo-causal impact of the presence of bus routes and bus traffic on observed crash frequencies by developing safety performance functions (SPFs) that include the presence of a bus route and estimated weekly bus traffic as input variables. The SPFs were developed using the propensity score–potential outcomes (PS-PO) framework to reduce unobserved biases that might exist between segments that have and do not have bus routes. The results suggest that PS-PO reduced standardized biases significantly, allowing stronger causal inferences to be obtained. The results revealed that the presence of a bus route was associated with a 27% increase in expected crash frequency after controlling for other infrastructure-related variables.

This paper introduces a comprehensive approach that considers an entire freeway corridor as a system consisting of successive independent bottlenecks with different characteristics, and can be used to estimate the optimum sustainable volume. The methodology is based on the sustained flow index, which is defined as the product of traffic volume and the probability of survival at this volume. Optimum volumes of two real-world corridors are estimated based on the new derivations. The empirical results reveal that the optimum volume and the capacity of an entire corridor is less than those of its most restrictive bottleneck.

This article evaluates the predicted air quality impacts of the 2016 revision (rollback) of a Clean Truck Program at the Port of New York & New Jersey. Air pollution emissions from marine port truck activity can pose significant health risks to communities living near ports. One approach to reducing these risks is requiring the use of low-emission trucks at port facilities. This analysis uses the best publicly available information to estimate emissions, concentrations, and health risks at a fine spatial scale across eight counties in New Jersey in 2017 and 2018. The examination of pollution and health outcomes of clean truck programs can inform the design and implementation of pollution reduction plans for other ports, some of which are considering implementing programs similar to the Clean Truck Program.

Unmanned Aerial Vehicles (UAVs), or drones, are an important emerging technology in the field of last-mile freight deliveries. As they are electric vehicles, many assume they provide a reduction in greenhouse and other emissions compared to conventional gas or diesel powered delivery trucks. The author develops a model to simulate the energy demand of various last-mile delivery solutions, including drones, diesel trucks, and electric trucks. The results of the model indicate that drones consume a similar amount of energy as diesel trucks, and therefore do not provide a benefit to air quality. Electric trucks require the least amount of energy and produce the least amount of emissions, although drones may consume the least amount of energy in rural contexts with large distances and low customer density.

Automated enforcement programs have been an important tool for improving traffic safety. Previous work provides strong evidence supporting the impact that these programs have on increasing safety either on a micro-level (e.g., road segments), or at a macro-level (e.g., neighborhood, city). In both cases, there are many variables that can influence and affect the safety impacts of the enforcement program. Additionally, there is a lack of understanding of how specific deployment parameters (e.g., how often to visit an enforcement site) can influence the overall safety on a macro-level (e.g., traffic analysis zone). The objective of this study is to quantify the impact that automated enforcement has on collisions on a macro-level as well as to develop models that would provide enforcement authorities with an empirical tool to help plan their deployment strategy.

Much of the earlier work on rural safety focused on state-maintained roadways and little is known about the safety performance of low-volume county-maintained roads. This study involved the estimation of safety performance for rural county roadways (paved and gravel). This was accomplished through the development of safety performance functions (SPFs) to estimate the number of annual crashes at a given highway segment, crash modification factors to determine the impacts associated with various roadway and geometric characteristics, and severity distribution functions (SDFs) to predict the crash severity.

The National Transportation Safety Board (NTSB) recently urged all 50 states to enact laws that would require cyclists to wear helmets. The NTSB argued that helmet laws will help stem the increasing number of bicyclist fatalities occuring on U.S. roads. However, bicycle advocates are disappointed with the helmet component of NTSB's announcement. They contend that the proper way increase cyclist safety is to improve roadway infrastructure for bicyclists, which, along with lower speeds, are the other cpmponents of the NTSB recommendation.

It states that since the city instituted a "toxicity charge" in the city center in February 2017, nitrogen dioxide pollution has fallen 36 percent. The toxicity charge applies to vehicles with higher emissions levels. The city built on its toxicity charge by implementing an Ultra Low Emissions Zone in April 2019, where cars are required to meet specific emissions standards or pay a daily fee. Since implementation, there have been 13,500 fewers cars entering the zone each day.

On October 3, New York City began restricting the number of vehicles that could travel on Manhattan's busy 14th Street between 6 a.m. and 10 p.m. The change was originally planned as a mitigation measure to allow for the high number of shuttle buses that would travel down 14th Street to replace L train service while the train line was under construction. A recent change in the construction plan allowed the L train to remain operational, but the plan to restrict traffic on 14th Street remained in effect. In the first two weeks since the restriction went into effect, the on-time performance of the buses on the 14th Street bus route has increased 16 percent, trip times have decreased from 15 minutes to 10 minutes, and ridership has increased 18 percent. Metropolitan Transit Authority officials are considering other streets where similar restrictions could reduce congestion for buses.
