This paper proposes a mobility system serving as an innovative platform that synchronises a ridesharing model and an Activity Travel Pattern (ATP) generator, enabling a synergistic enhancement of participants’ mobility experiences. Through system-level integration, it can significantly improve the performance of ridesharing systems while also exploring the intricate relationship between ridesharing and participants’ ATPs. Numerical examples demonstrate the advantages of ridesharing systems when armed with flexible/variable announcements from the ATPs-based participants. The results show that incorporating ATP-based announcements in the system increases the chances of finding a match, and the attractiveness of the ridesharing mode for participants is improved. Despite their lower number, ATP-based participants contribute significantly to finding matches and obtaining distance savings. The study also highlights the key role of tour gyration in the performance of the ridesharing system. It incentivises participants with distant activity locations to join the ridesharing system as ATP-based participants.

This paper introduces a novel toll charge to regulate transportation of hazardous materials (hazmat), taking into account that carriers are bounded rational decision-makers. In the case of bounded rationality, the route choice behaviour of carriers is described based on the link-based perception error model. Then, a novel bi-level programming model is developed, which aims to minimise both total tolls and maximum total risk, while finding the shortest path according to certain perception errors. To effectively solve the proposed model, it is decomposed into two subproblems, and the particle swarm optimisation algorithm and K-shortest paths algorithm are designed. Furthermore, an extended model is developed to ensure risk equity between different links, where the constraints on maximum link risk are added. Numerical experiments are conducted to validate the proposed models and algorithms, demonstrating that maximum total risk can be effectively mitigated and risk equity between different links can be achieved.

A two-stage variable speed limits (VSL) modelling framework is proposed to enhance traffic safety and efficiency at freeway bottlenecks with mixed traffic flow comprising both human-driven and autonomous vehicles. The first-stage macroscopic VSL control framework is based on an extended cell transmission model (ECTM) and a VSL optimal control model. The ECTM serves as a traffic state predictor and characterises mixed traffic flow by modelling various characteristics such as driving behaviours and flow performance. The ECTM-based optimal control model aims to improve safety and efficiency. The second-stage microscopic validation framework is designed using the VISSIM_COM to validate the effectiveness and sophistication of the proposed VSL strategy. The proposed strategy is compared with a fixed speed limit strategy (FSL) and a VSL strategy considering only efficiency improvement (VSL_E). The results demonstrate that the proposed strategy improves traffic efficiency compared to the FSL and significantly outperforms VSL_E in traffic safety.

In this paper, we develop a new transportation network redundancy measure by integrating the route diversity and spare capacity dimensions, which have been demonstrated as two complementary dimensions of redundancy and assessed separately in the literature. Instead of modelling redundancy as two separate measures with significantly different units and scales, an integrative measure is beneficial for comprehensive comparison and selection of redundancy enhancement schemes. Specifically, we represent the transportation network by adding a virtual link directly connecting each origin-destination (O-D) pair. The virtual link choice probability is affected by both the route diversity of the O-D pair and the spare capacity of these routes, which is used in the proposed measure. Numerical examples in the realistic Winnipeg network are conducted. The effectiveness of the proposed measure is further verified by applying it to identify the critical links in the Shanghai Expressway Network, where a severe traffic accident happened in 2016.

Urban rail transit (URT) systems operate in heterogenous environments where their performance is affected by many exogenous factors. However, conventional benchmarking methods assume homogeneity of many of these factors which could result in misleading comparisons of performance. This study provides a methodological contribution to the transit benchmarking literature through a systemic data-driven method which accommodates heterogeneity among URT. A unique international dataset of 36 URT systems in year 2016 is utilised. Operators are clustered based on indicators of operational performance through machine learning algorithms which enables like-for-like comparisons of performances. Data envelopment analysis with bootstrapping is then used to evaluate operators’ efficiency performance within a cluster. Further, ANOVA and post-hoc tests are applied to explore variations and correlations among different aspects of performance. Our clustering results corroborate the natural geographic grouping of the systems. Further, we highlight the complexity of the definition of service quality in the transit sector.

Highway motorcycle-barrier crashes are uncommon but are associated with severe ramifications. Little has been done to understand the factors related to these crashes, making it difficult to establish appropriate mitigation policies. This study identifies homogeneous groups of motorcycle-barrier crashes on highways and investigates cluster-specific key factor associations and the determinants of injury severity. Cluster Correspondence Analysis was employed to discover latent clusters and cluster-specific key factor associations using motorcycle-barrier crashes from Massachusetts. Further, an ordered probit regression technique was employed to investigate the effect of factors on injury severity outcomes at the cluster level. Three highway access control type-related clusters were identified. While seniors, collectors, intersections/roundabouts, daylight, and summer were associated with no/partial access-controlled segment crashes, interstates, ramps, medians, dark-lighted roads, and winter correlated with full access-controlled segment crashes. Factors influencing fatalities differed for each cluster. From the insightful findings, targeted countermeasures geared at improving motorcycle safety are suggested.

Recently, user equilibrium models with uncertainty were proposed to describe stochastic travel time in road networks. The accurate estimation of a stochastic link capacity is important for such models. This study develops a method for estimating a stochastic link capacity by considering the uncertainty of the driver’s behaviour. We postulate that the stochastic link capacity follows a lognormal distribution. The characteristics of the lognormal distribution suit real traffic observation, e.g. nonnegativity, asymmetricity, and long-tailed. Furthermore, the estimated link capacity can derive the analytical likelihood function for the link performance function. Then, the link performance function can be estimated analytically by explicitly considering the source of uncertainty. The proposed methods can contribute to the estimation of stochastic link capacity and the link performance function for the user equilibrium model with stochastic travel time. A numerical calculation demonstrates the proposed method using real traffic observations in Sapporo, Japan.

The study develops a new optimisation model to design a bimodal transit system from a microeconomic view to maximise the profit of a transit agency considering heterogeneous demand elasticity and different fare structures. Bimodal transit network parameters are optimized to better serve passenger demand. An elastic demand function is devised to include various time components and incorporate flat, distance-based, and hybrid fares. A nested iterative procedure is developed to find a near-optimal solution. Numerical experiments reveal the following interesting findings. First, the increase in elasticity parameters has a knock-on effect on the financial performance, consequently leading to a net profit reduction. Second, a distance-based fare scheme brings in the least actual demand but makes the most profit, compared with the flat and hybrid fare schemes. Third, passengers prefer using a rail-bus system to a BRT-bus system, especially at a higher demand level.

On the one hand, fully flexible demand-responsive feeder services efficiently tailor their service to passengers' needs. Traditional services, on the other hand, offer predictability and easier cost control. This paper considers a semi-flexible feeder service that combines positive characteristics of both traditional and fully flexible services. There are two types of bus stops in this service. Mandatory bus stops have a maximum allowable headway for bus departures. Optional stops are only visited when there is demand for transportation nearby. When new passenger requests arrive, the performance of this feeder service is optimised in real time. A metaheuristic with two phases is developed to optimise the service. The dynamic optimisation method is compared to a model that optimises the service when all requests are known beforehand. The results show that the dynamic method has an average gap of 6.5% with respect to the static model and an average acceptance rate of 95.1%. A case study in the city of Antwerp shows that, when compared to existing transit options in the region, this feeder service can increase the service quality by 31.6% when enough resources are available.

Clustering activity patterns and identifying homogeneous travel behaviour through trip chain sequences offer valuable insight for transportation planners and policymakers in addressing transport equity problems and travel demand management. This study explores how income and car-ownership levels determine mobility patterns and travellers' decisions. Unlike previous studies that investigated the travel mode and destinations separately, we designed a novel, aggregated form considering the trip purpose and associated transport mode use as a unit of our analysis. To mitigate the subjectivity of rule-based approaches for trip chain analysis, we employ a novel sequence clustering framework to extract homogeneous clusters of activity patterns. Our results reveal that income and car-ownership levels influence travellers' travel decisions and mobility patterns. Among low-income carless households, 37% of their daily trips include care activities where women more frequently than men play this traditional role in a household by either public transit or a car as a passenger. In the low-income car-owner subsample, females still use public transit for their work trips, whereas males more often use the available car to commute to work. Males of wealthy carless households integrate public transit and active transportation for their daily trips when they live in high-density and more accessible neighbourhoods. While our findings demonstrate the impact of car ownership, income, and built environment on trip-chaining behaviour, we recognise that achieving transport equity will require tailored transportation and land use policies and investments that address the specific needs and barriers faced by different household types, particularly the most vulnerable ones in terms of sociodemographic characteristics, accessibility levels, and affordability issues. Hence, we recommend that policymakers and planners take a more holistic approach to transportation planning that considers the interplay of these factors to ensure that transportation systems and services are accessible, affordable, and equitable for all.
