  • Understanding and Predicting Travel Time with Spatio-Temporal Features of
           Network Traffic Flow, Weather and Incidents
    • Authors: Shuguan Yang;Sean Qian;
      Pages: 12 - 28
      Abstract: Travel time on a route varies substantially by time of day and from day to day. It is critical to understand to what extent this variation is correlated with various factors, such as weather, incidents, events or travel demand level in the context of dynamic networks. This helps a better decision making for infrastructure planning and real-time traffic operation. We propose a data-driven approach to understand and predict highway travel time using spatio-temporal features of those factors, all of which are acquired from multiple data sources. The prediction model holistically selects the most related features from a highdimensional feature space by correlation analysis, principle component analysis and LASSO. We test and compare the performance of several regression models in predicting travel time 30 min in advance via two case studies: (1) a 6-mile highway corridor of I-270N in D.C. region, and (2) a 2.3-mile corridor of I-376E in Pittsburgh region. We found that some bottlenecks scattered in the network can imply congestion on those corridors at least 30 minutes in advance, including those on the alternative route to the corridors of study. In addition, real-time travel time is statistically related to incidents on some specific locations, morning/afternoon travel demand, visibility, precipitation, wind speed/gust and the weather type. All those spatiotemporal information together help improve prediction accuracy, comparing to using only speed data. In both case studies, random forest shows the most promise, reaching a root-mean-squared error of 16.6% and 17.0% respectively in afternoon peak hours for the entire year of 2014.

  • An Automated Vehicle Fuel Economy Benefits Evaluation Framework Using
           Real-World Travel and Traffic Data
    • Authors: Lei Zhu;Jeffrey Gonder;Eric Bjarkvik;Mitra Pourabdollah;Bjorn Lindenberg;
      Pages: 29 - 41
      Abstract: Increasing automation is a consistent development trend in the automobile industry. However, real-world evaluation of the operational and energy consumption differences between automated vehicles and comparable manually driven vehicles has been limited. This study helps fill the information gap by comparing the operation and fuel economy of vehicles in adaptive cruise control (ACC) and non-ACC modes based on large-scale field test data collected by Volvo Car Corporation (Volvo Cars) from vehicles traveling on the designated "Drive Me" project road network in Gothenburg, Sweden. The test vehicles' travel data are classified by driving mode (ACC vs. non-ACC) and driving conditions, which refer to traffic speed and road grade in this study. The results from the data logging fleet are used to estimate the aggregate fuel consumption differences at the Drive Me road-network level for vehicles traveling in ACC vs. non-ACC mode based on appropriately weighting the total amount of travel that took place on the network under different driving conditions. At the ACC penetration levels observed in the field test data, vehicles tended to drive more smoothly in ACC mode than in non-ACC mode. The corresponding travel-weighted fuel consumption rate for vehicles in ACC mode was about 5%-7% lower than for vehicles in non-ACC mode when traveling at similar conditions. Sensitivity analyses impart confidence in this result, and in the future, the established evaluation framework could be used to objectively quantify potential on-road fuel consumption impacts from vehicles with even higher levels of automated driving capability.

  • Energy-Efficient Adaptive Cruise Control for Electric Connected and
           Autonomous Vehicles
    • Authors: Chaoru Lu;Jing Dong;Liang Hu;
      Pages: 42 - 55
      Abstract: This paper presented an energy-efficient adaptive cruise control, called Energy-Efficient Electric Driving Model (E3DM), for electric, connected, and autonomous vehicles (e-CAVs) in a mixed traffic stream. E3DM is able to maintain high energy efficiency of regenerative braking by adjusting the spacing between the leading and the following vehicles. Moreover, a power-based energy consumption model is proposed to estimate the on-road energy consumption for battery electric vehicles, considering the impact of ambient temperature on auxiliary load. Using the proposed energy consumption model, the impact of E3DM on vehicle energy consumption is investigated. In particular, single-lane vehicle dynamics in a traffic stream with a mixed of e-CAVs and human-driven vehicles are simulated. The result shows that E3DM outperforms existing adaptive cruise control (i.e. Nissan-ACC) and cooperative adaptive cruise control (i.e. Enhanced-IDM and Van Arem Model) strategies in terms of energy consumption. Moreover, higher market penetration of e-CAVs may not result in better energy efficiency of the entire fleet. The reason is that more e-CAVs in the traffic stream results in faster string stabilization which decreases the regenerative energy. Considering mix traffic streams with battery electric (BEVs) and internal-combustion engine (ICEVs) vehicles, the energy consumption of entire fleet reduces when the market penetration of BEV (contains both e-CAV and human-driven BEV) increases. A higher ratio of e-CAV to human-driven BEV results in higher energy efficiency.

  • Distributed Traffic Speed Control for Improving Vehicle Throughput
    • Authors: Yue Zu;Chenhui Liu;Ran Dai;
      Pages: 56 - 68
      Abstract: This article presents a real-time speed control strategy for vehicle throughput improvement on highway. Using Barron-Jensen/Frankowska (B-J/F) solution to Hamilton-Jacobi (HJ) Moskowitz function, we formulate a Convex Quadratic Optimization Problem (CQOP) solved by Quadratic Programming (QP). Unlike with previous investigation on optimal control of scalar conservation law, a distributed framework is constructed based on dual decomposition and subgradient method via networked Road Infrastructures (RIs). Instead of relying on complex RIs network for information collection, the distributed method only depends on local traffic information and iteratively approaches to feasible solutions constrained by flow consensus. For both uniform and non-uniform road conditions, the proposed distributed algorithm is verified to be able to improve the vehicle throughput, reduce traffic delay and alleviate congestion in simulation.

  • Low-Cost Road Traffic State Estimation System Using Time-Spatial Image
    • Authors: Ekalux Ua-areemitr;Agachai Sumalee;William H.K. Lam;
      Pages: 69 - 79
      Abstract: Road traffic mobility can be described by its Level of Services (LoS). A major challenge in traffic state and LoS estimation is the limitation of observed traffic data. To derive the traffic state of a road network, a sensor network needs to be installed. Most stationary sensing techniques involve high investment in terms of the sensor installation, data communication and computational resources. This paper proposes a low-cost image processing system for road traffic state estimation using time-spatial image (TSI) processing. The TSI is an image processing technique for transforming a series of video images into a single image. Therefore, the TSI can reduce memory resources compared with the traditional methods. A camera can be exploited for traffic-state estimation through integration with TSI generating and processing modules. In addition, traffic state variables such as space-mean-speed, flow and density can be estimated. Empirical results are provided based on several experiments to show that TSI processing is a viable lowcost approach to traffic state estimation.

  • An Optimal Game Approach for Heterogeneous Vehicular Network Selection
           with Varying Network Performance
    • Authors: Xiangmo Zhao;Xiaochi Li;Zhigang Xu;Ting Chen;
      Pages: 80 - 92
      Abstract: Most conventional heterogeneous network selection strategies applied in heterogeneous vehicular network regard the performance of each network constant in various traffic scenarios. This assumption leads such strategies to be ineffective in the real-world performance-changing scenarios. To solve this problem, we propose an optimal game approach for heterogeneous vehicular network selection under conditions in which the performance parameters of some networks are changing. Terminals attempting to switch to the network with higher evaluation is formulated as a multi-play non-cooperative game. Heterogeneous vehicular network characteristics are thoroughly accounted for to adjust the game strategy and adapt to the vehicular environment for stability and rapid convergence. A multi-play non-cooperative game model is built to formulate network selection. A probabilistic strategy is used to gradually drive players toward convergence to prevent instability. Furthermore, a system prototype was built at the Connected and Automated Vehicle Test bed of Chang'an University (CAVTest). Its corresponding test results indicate that the proposed approach can effectively suppress the ping-pong effect caused by massive handoffs due to varying network performance and thus well outperforms the single-play strategy.

  • Traffic Volume Estimation in Multimodal Urban Networks Using Cell Phone
           Location Data
    • Authors: Jiping Xing;Zhiyuan Liu;Chunliang Wu;Shuyan Chen;
      Pages: 93 - 104
      Abstract: This paper proposes a method to estimate multimodal traffic volume on urban road networks using cellphone location data. The study considers the fact that there can be more than one phone user in each driving vehicle. Firstly, a temporal and spatial method is used to distinguish whether the cellphone signals are sent by cellphones in running vehicles on urban roads. Secondly, a minimum spanning tree clustering method is proposed to calculate the number of commuters in each vehicle. Based on the proposed method, the various travel modes, including drive alone, carpooling, and bus, can be identified while their hourly traffic volume can be estimated. Finally, the predicted traffic volumes are compared with the actual values obtained from License Plate Recognition system. The experiment result shows that the proposed method can accurately estimate the hourly traffic volumes of different travel modes and the estimation errors of this method are within a reasonable range.

  • Demand Estimation for Aerial Vehicles in Urban Settings
    • Authors: Milos Balac;Amedeo R. Vetrella;Raoul Rothfeld;Basil Schmid;
      Pages: 105 - 116
      Abstract: The idea of flying has always fascinated mankind. A century ago it became reality when in 1914 the first commercial flight was offered. In recent times, many entities are planning, developing and testing aerial vehicles and systems that will move goods and people in urban scenarios. Consequently, the need to develop appropriate planning tools and to investigate the potentials for this kind of transportation is needed. In this paper we present a methodology for simulation and demand estimation for personal aerial vehicles (PAVs) in urban settings. The methodology is then utilized to analyze the impacts of PAVs with different vehicle and system parameters on the demand. The findings show that with higher automation and falling prices, PAVs have a potential to be an important transportation mode, by serving not only middistance trips, but also shorter trips in urban settings. The analysis also show that unlike for car and public transport service, vehicle parameters of PAVs have a substantial impact on the demand and turnover. Furthermore, an optimization procedure that minimizes fixed costs of the PAVs by minimizing the fleet size and variable costs by minimizing the empty kilometers of PAVs for the estimated demand in the region of Zurich, Switzerland, is proposed. Optimized service ensures that much wider range of possible vehicle concepts can be utilized to serve the demand.

  • A Speed Control Method at Successive Signalized Intersections Under
           Connected Vehicles Environment
    • Authors: Yingrong Lu;Xiaotong Xu;Chuan Ding;Guangquan Lu;
      Pages: 117 - 128
      Abstract: A growing body of speed control methods for signalized intersections have been developed using V2I and V2V technology. However, limited efforts are made to reduce the vehicle fuel consumption and emissions during the driving process at successive signalized intersections. To fill the gaps, this paper proposed a novel speed control method for the successive signalized intersections under connected vehicles environment. Using the upcoming traffic signal phasing, timing information and the vehicle queues at the signalized intersection, vehicle speed was optimized to reduce the vehicle fuel consumption and emissions. To validate its effectiveness, a real-time simulation framework embodied the characteristics of the connected vehicles environment is conducted using the multi-agent technology. In different traffic flows, the fuel consumption, CO2 emissions and travel time based on the speed control method are compared with that of without speed control. The effectiveness of the proposed speed control method in different signal timing plan was also tested. Simulation results show that the proposed speed control method could reduce more than 18% fuel consumption and CO2 emissions and 9% travel time in the medium density of traffic flow, which is the best control effect.

  • Dynamic Cellular Learning Automata for Evacuation Simulation
    • Authors: Xin Ruan;Zeren Jin;Huizhao Tu;Yue Li;
      Pages: 129 - 142
      Abstract: Pedestrian behaviors are essential for the evolution of an evacuation process and the eventual evacuation time. Such behaviors are mainly determined by the information available to a pedestrian at a certain position. To obtain a more comprehensive base for sensible movement choices, a pedestrian is expected to extend the range of information acquirement, which can be reflected in spatial and temporal concepts. The existing models for evacuation simulations mainly address the extension of information in a spatial concept. In fact, a pedestrian is more likely to update his movement choice based on the experiences accumulated throughout the evacuation process, as defined by information extension in a temporal concept. This paper develops a model to achieve an adaptive choice-making process. Two learning automata are proposed to update the imitation preferences for certain pedestrians and to make decisions between independent movement and imitation. Sensitivity analyses are performed using several key parameters to understand the mechanism of the proposed model. The proposed model is compared with the floor field model in terms of evacuation time and process, showing a high performance in describing pedestrian movement characteristics at different stages of an evacuation process.

      Pages: 143 - 157
      Abstract: Shared mobility refers to the shared use of a motor vehicle, bicycle, or other low-speed transportation modes, which has significant influences on transportation systems. Among different types of shared mobility, ridesplitting is developing the most rapidly because of the emergence of transportation network companies. In this study, we present exploratory evidence of on-demand ridesplitting's impacts on the vehicle use and purchase willingness using the emerging ridesourcing real-world data (i.e., app-based, on-demand ride services like Uber and DiDi Chuxing) in Hangzhou, China. We explore ridesplitting users' travel habits and their transportation modal shift behavior if the ridesplitting services are unavailable, and how ridesplitting impacts the use of public transit and private cars. In summer 2017, an online survey was conducted with respondents who had completed ridesourcing journeys within one month before the investigation. We compare the survey results with two-week ridesourcing order data provided by DiDi Chuxing, 20% of which are ridesplitting orders (including DiDi Hitch and Express ridesplitting). Considering the modal shift from public transit to ridesplitting, the findings indicate that (I). In the short term, ridesplitting services reduce the number of vehicles on road (decreased by 3,051 veh/day, nearly 2.6‰ of the vehicle ownership in the urban area of Hangzhou). (II). In the intermediate term with the development of ridesplitting, the total decreased number of vehicles is estimated to be 4,129 veh/day (nearly 3.6‰ of the vehicle ownership). An interesting phenomenon is that Hitch's influences on the vehicle usage in the intermediate term is not obvious as the influence in the short term due to travelers' modal shift from public transit. (III). In the long term, ridesplitting will reduce the car purchase willingness and influence people's travel behavior to some extent. This paper shines light on quantita-ively exploring the influence of on-demand ridesplitting on the vehicle use and purchase willingness.

  • Spatial Interpolation of Missing Annual Average Daily Traffic Data Using
           Copula-Based Model
    • Authors: Xiaolei Ma;Sen Luan;Chuan Ding;Haode Liu;Yunpeng Wang;
      Pages: 158 - 170
      Abstract: Accurate estimation of traffic counts [(i.e., annual average daily traffic (AADT)] is essential to transportation agencies for traffic demand forecasting, emission evaluation, pavement design, and project prioritization. Traditional AADT estimation methods rely on either temporal data imputation techniques based on historical records or kriging-based spatial interpolation approaches. However, Kriging method utilizes the correlation function as the sole descriptor of spatial dependency, posing limitations to yield accurate interpolation results for unstable AADTs under complex traffic patterns due to diverse road functions or land uses. This study proposed a copula-based model that combines spatial dependency and marginal distribution for missing AADT interpolation to weaken the limitation of Kriging method. Thus, the proposed model not only can describe the spatial dependency but also is robust to outliers. AADT data collected from the California state highway network were used to evaluate the effectiveness of spatial copula models with varying missing data rates. Four road segments with regular and recreational traffic patterns were selected to compare with existing kriging-based approaches. Results suggested that the spatial copulas yielded significantly higher accuracy rates than kriging did for irregular travel patterns with high missing data rates. Spatial copula models hold a great potential to improve the performance of large-scale transportation network-wide data imputation for planning and operational usages.

  • Clusters of Driving Behavior From Observational Smartphone Data
    • Authors: Josh Warren;Jeff Lipkowitz;Vadim Sokolov;
      Pages: 171 - 180
      Abstract: Understanding driving behaviors is essential for improving safety and mobility of our transportation systems. Data is usually collected via simulator-based studies or naturalistic driving studies. Those techniques allow for understanding relations between demographics, road conditions and safety. On the other hand, they are very costly and time consuming. Thanks to the ubiquity of smartphones, we have an opportunity to substantially complement more traditional data collection techniques with data extracted from phone sensors, such as GPS, accelerometer gyroscope and camera. We developed statistical models that provided insight into driver behavior in the San Francisco metro area based on tens of thousands of driver logs. We used novel data sources to support our work. We used cell phone sensor data drawn from five hundred drivers in San Francisco to understand the speed of traffic across the city as well as the maneuvers of drivers in different areas. Specifically, we clustered drivers based on their driving behavior. We looked at driver norms by street and flagged driving behaviors that deviated from the norm.

  • Detecting Pickpocketing Gangs on Buses with Smart Card Data
    • Authors: Xia Zhao;Yong Zhang;Hao Liu;Shaofan Wang;Zhen Qian;Yongli Hu;Baocai Yin;
      Pages: 181 - 199
      Abstract: Detecting pickpocketing gangs on buses is critical for safety and public security department. Knowing this both in real time and from historical records would allow effective law enforcement and crime prevention. However, very little research has been devoted into identifying pickpocketing gangs in an automated and holistic manner. This research utilizes smart card data generated by bus riders to identify pickpocketing gangs, who possess distinct characteristics from regular passengers. Particularly, we create a dataset of 1,098 pickpockets among 4.06 million bus riders in August, 2015 in Beijing automatically and efficiently based on an efficient labeling model of outliers. This model examines anomaly of passengers using the so-called relative outlier cluster factor and local outlier factor. The proposed mobility patterns of pickpockets are then learned based on supervised classification. Pickpockets from the derived dataset form a pickpocketing network, which is modeled as a graph with vertices denoted as discrete pickpockets, and edge weight quantified by a combined similarity on mobility pattern, space and time. A graphbased Louvain algorithm is adopted to detect pickpocketing gangs. Experiments are conducted on SINA microblog data to verify the detected pickpocketing gangs identified by the proposed framework. Results show that the framework detects 63 pickpocketing gangs and verifies 34 gangs by microblogs, with recall value 0.85. Findings from this research can assist police and public safety departments in the city in taking pro-active actions to track down pickpocketing gangs.

  • Analysis of the Influencing Factors of Carpooling Schemes
    • Authors: Kai Huang;Zhiyuan Liu;Inhi Kim;Yong Zhang;Ting Zhu;
      Pages: 200 - 208
      Abstract: Carpooling, as an emerging travel mode, has not yet been paid sufficient attention despite its merits of convenience, cost-efficiency, and sustainability. The studies of carpooling, especially on the factors influencing carpooling, are inadequate. To tackle this problem, what and how the factors influence travelers' mode choice are studied with a practical trial. Based on a qualitative survey, we found that the travel time, travel cost, safety, punctuality, comfort, social contact, and identity promotion are potential influencing factors. Then a stated preference (SP) survey is conducted to address the main factors influencing carpooling. Finally, three key factors (travel time, travel cost, and safety) are singled out and the interaction of travel time and travel cost are explored by a binary logit regression analysis, respectively. Following the findings of the main factors and their interaction, related suggestions are proposed to promote the future application of carpooling.

  • Queue Length Estimation for Signalized Intersections Using License Plate
           Recognition Data
    • Authors: Xiaoqin Luo;Dongfang Ma;Sheng Jin;Yue Gong;Dianhai Wang;
      Pages: 209 - 220
      Abstract: Queue length is an important variable in evaluating the performance of traffic management systems, especially under congested conditions. This problem has been studied in the literature based on different kinds of traffic sensors, such as loop detectors and other mobile sensors. Automatic Number Plate Recognition systems and Automatic Vehicle Identification systems have received significant attentions due to their active deployments in recent years, which provides massive License Plate Recognition (LPR) data sources. In this paper, new methods for queue length estimation at signalized intersections are proposed using LPR data and signal schemes, with the key point being the intrinsic connections between travel time of individual vehicles and queue composition in each cycle. The queue length in the previous cycle is calculated by considering the detailed trajectories of individual vehicles. Due to the hysteresis of the queue length in the previous cycle, the queue length in the immediate past cycle is formulated as a prediction problem using regression analysis. The algorithms were evaluated using field data of Guiyang city in China, and the proposed models' results fully coincide with the experimental findings even in congested conditions.

  • Multi-source traffic data reconstruction using joint low-rank and
           fundamental diagram constraints
    • Authors: Yang Wang;Yong Zhang;Zhen Qian;Shaofan Wang;Yongli Hu;Baocai Yin;
      Pages: 221 - 234
      Abstract: Accurate and complete traffic information plays an important role in traffic monitoring, traffic state estimation and prediction in all intelligent transportation systems. However, in practice, data provided from various types of traffic sensors may suffer from many issues, such as heterogeneity, missing data and bias. Therefore, extracting unbiased, accurate and complete data from multiple traffic data sources, referred to as multi-source traffic data reconstruction, is critical before data can be utilized. There are many existing methods for multi-source traffic data reconstruction, but two issues remain challenging and unaddressed: the effectiveness of reconstruction is fairly limited to attributes of available data, especially data loss ratio and reliability; the probability distribution of data assumed, which brings in bias prior to data analytics. This paper proposes a novel framework that integrates low-rank representation and fundamental traffic flow models into multi-source traffic data reconstruction. It makes full use of multi-source data, and can simultaneously impute missing data and eliminate outliers/errors. Multiple parameters in the traffic flow models are learned from large-scale spatio-temporal data, which ensures the extracted and imputed data are consistent with traffic flow physics. Experimental results on real-world traffic data demonstrate the superiority of this method over existing methods.
