Tools and methods for the understanding of road users behaviours (by S. Espié)

To be efficient and accepted, because acceptable, road safety counter-measures need to be defined thanks to scientific studies. The question is not only to imagine an optimal solution in the absolute, but to understand the real practices and, based on this knowledge, to design the measures (sensitivity campaigns, changes in Highway Code, changes in initial training curriculum or licence tests, infrastructure (re)design, vehicles homologations, etc.).
In our talk we will describe the tools and methods we promote and refined for decades to improve road safety, and their use in research projects. Our approach is systemic and is based on three pillars: instrumentation of vehicles for in-depth naturalistic studies, traffic modelling and simulation using a multi-agents system, and design of driving simulators to study driving behaviours. We will illustrate our approach using research projects we have conducted over these last years.

 

Driving-Pattern Identification and Event Detection Based on an Unsupervised Learning Framework: Case of a Motorcycle-Riding Simulator
(by A. Boubezoul)

Analysis of human driving behavior aims to inspect drivers’ behavior in the real-world and in a virtual environment. The study of driving behaviors can be conducted in naturalistic situations or controlled experiments. Analyzing driving behaviors based on the data collected in naturalistic driving experiments or controlled experiments in the real-world or in a virtual environment is beneficial to fill in many of the knowledge gaps about driving behaviors and risk factors. I will present a multi-step framework for analyzing driving behavior on macroscopic and microscopic scales. The core step of this framework is based on unsupervised machine learning algorithms applied to driving-pattern identification and the detection of critical driving events using anomaly-detection algorithms. The detected events are interpreted and described by computing their feature importance using graphs centrality measures. This provides new insight into driving behavior by identifying the motives behind the driver’s actions.

Meeting #32 – Analog games as tools for planning processes [online]

Event date: December 17, 2020 | Added on

This 1-hour session will take place online on Thursday, November 17th 2020, from 11a.m. to 12p.m.. Micael Sousa, Ph.D. student of the Spatial Planning from University of Coimbra will share his ongoing research work entitled Analog games as tools for planning processes.

 

Abstract

This research is focused on the potential of game mechanics and dynamics, mostly through analog platforms, as tools for planning processes. Through this approach of serious games, planners can establish new processes, applied to any field of planning, where games can help enhancing participation and collaboration among experts, stakeholders, and citizens. Serious games are ways to engage with participants, providing pleasant simulation experiences while granting planning objectives. Analog games are prone to foster collaboration and are flexible tools to adapt to ongoing planning processes.

Meeting #28 – The impact of reversible lanes in the main freeway (VCI) of Porto city

Event date: July 23, 2020 | Added on

 

GITMob meeting no. 28
This session will take place online on 23 July 2020 (no registration required: Zoom Link). The topic of this session will be The impact of reversible lanes in the main freeway (VCI) of Porto city, presented by Lígia Conceição ORCID iD, Ph.D. in Transportation Systems. This presentation focuses on her research work.

 

Abstract
In real-world cities, solving Road Network Design Problems (RNDP) in a single-level framework through optimization is not advisable, given the numerical complexity that turns the process very time-consuming. Simulation methods appear as a method to reduce the complexity of the mathematical problem by solving one part of the problem: the lower-level problem, i.e., the performance of the network for a given network design solution. Joining simulation and optimization is also challenging in terms of programming, software interfaces, and time resources, yet a feasible solution can be obtained even when the solution process does not reach the end. The main objective of this presentation is to present the first results of a simulation-optimization (SO) framework of reversible lanes (a smart traffic control system) applied to a particular case-study: the main freeway (also known as VCI) of the city of Porto, in Portugal.

Meeting #27 – The Reversible Lane Network Design Problem (RL-NDP) for Smart Cities with Automated Traffic

Event date: July 16, 2020 | Added on

 

GITMob meeting no. 27
This session took place online (no registration required, Zoom link) on 16 July 2020. The topic of this session was The Reversible Lane Network Design Problem (RL-NDP) for Smart Cities with Automated Traffic, presented by Lígia Conceição ORCID iD, Ph.D. in Transportation Systems. This presentation focused on her recently published work available here.

 

Abstract
With automated vehicles (AVs), reversible lanes could be a sustainable transportation solution once there is vehicle-to-infrastructure connectivity informing AVs about the lane configuration changes. This paper introduced the reversible lane network design problem (RL-NDP), formulated in mixed-integer non-linear mathematical programming—both the traffic assignment and the reversible lane decisions were embedded. The model was applied on an hourly basis in the case study of the city of Delft, the Netherlands. Reversible lanes are examined under no traffic equilibrium (former paths are maintained); user-equilibrium (UE) assignment (AVs decide their own paths); and system-optimum (SO) traffic assignment (AVs are forced to follow SO paths). We found out that reversible lanes reduce congested roads, total travel times, and delays up to 36%, 9%, and 22%, respectively. The SO scenario was revealed to be beneficial in reducing the total travel time and congested roads in peak hours, whereas UE is equally optimal in the remaining hours. A dual-scenario mixing SO and UE throughout the day reduced congested roads, total travel times, and delay up to 40%, 8%, and 19%, respectively, yet increased 1% in travel distance. The spatial analysis suggested a substantial lane variability in the suburbs, yet a strong presence of reversible lanes in the city center.
