“…This data-collection approach is effective for behavioral models in which the variables of interest are not known beforehand, as any distance and kinematic-related characteristics and variables can be generated from the trajectory dataset. The trajectory extractor adopted in this study has also been used by several other recent studies ( 4, 10, 30 ).…”

The maneuvering of powered two-wheelers (PTWs) is non-lane-based, and the interactions between PTWs and other vehicles in mixed traffic are complex. The behavior of PTWs, particularly in developing countries, is not the same as that of passenger cars, which has been studied for several decades. This study contributes to the existing literature on PTWs in several ways. A real-world microscopic vehicle trajectory database has been digitalized from a video clip for a four-lane urban arterial in Taipei (Taiwan). From a modeling perspective, a dynamic discrete choice model is proposed to capture the lateral-shifting behaviors of PTWs in mixed traffic conditions. The model considers not only the positions of all surrounding vehicles but also riders’ perception of expected traffic conditions. The behavioral model is able to describe the sequential non-lane-based maneuvers of PTWs, including not following lane discipline, filtering, moving abreast of other vehicles in the same lane, oblique following, swerving, and overtaking from the same lane. The results indicate that a better model fit is obtained when taking into account the dynamic nature of the problem. The data and methods proposed have the potential to improve microscopic traffic simulation of mixed traffic with a large amount of PTWs. Practical applications are concerned with the improvement of road geometries and the definition of control strategies for mixed traffic flows.

“…As PTW riders have peculiar patterns, the lack of knowledge about the behavior of PTWs might cause difficulties in managing mixed vehicular flow. Some characteristics of PTWs, such as filtering, moving abreast of other vehicles in the same lane, oblique following, and swerving are also discussed elsewhere ( 29 – 33 ).…”

This study showed that motorcyclists had a 66-74% compliance rate with the rule on helmet and headlight usage.…”

“…The use of sirens and lights is not in all cases limited to emergency situations; the motorcade of a government minister may, for instance, legally use sirens and lights to direct other motorists to give way. Vehicle design can also facilitate priority; motorcycles' narrow width enables them, in certain circumstances, to maneuver past standing queues of four-wheel traffic (Lee and Polak 2012). Physical design is also used to give network priority to certain vehicle types; bus and bicycle lanes are common examples.…”

A novel peer-to-peer congestion pricing marketplace enabled by vehicle-automation

This paper proposes a novel concept of congestion pricing based on voluntary peer-to-peer exchange of money between motorists in exchange for one ceding priority to another in a traffic stream. While in the classical congestion charging paradigm payments are compulsory and flow only towards the system operator, in the proposed marketplace participation is voluntary and motorists directly compensate each other. A particular motorist may find that he/she is a ‘payer’ at certain points in a given journey and a ‘payee’ at others. Humans would not be expected to successfully seek, negotiate and execute a continuous series of peer-to-peer trades involving micro-payments while also handling the cognitively-demanding task of driving; real-world implementation will therefore require vehicles operating under fully-automated control in both the longitudinal and lateral dimensions during the time periods that they seek and engage in trades. The automated vehicle control algorithms must be sufficiently intelligent and adaptable to enable alternative maneuvers on short timescales, given the inherent uncertainty of whether or not a potential trade will in fact be executed. The peer-to-peer trading would be executed algorithmically, subject to strategic-level guidance given by a vehicle’s occupant(s) regarding the occupant’s relative valuation of money and priority in the traffic stream. In this paper we detail the prospective marketplace and present a simple simulation model to expose its properties. We show that the proposed peer-to-peer marketplace could lead to both desirable and undesirable outcomes; which of these would be predominant is a matter requiring empirical study. The paper concludes with a discussion of further research needs to refine and develop these concepts into practice
