Microscopic driving theory with oscillatory congested states: Model and empirical verification

Abstract: The essential distinction between the Fundamental Diagram Approach (FDA) and Kerner’s three-phase theory (KTPT) is the existence of a unique gap–speed (or flow–density) relationship in the former class. In order to verify this relationship, empirical data are analyzed with the following findings: (1) linear relationship between the actual space gap and speed can be identified when the speed difference between vehicles approximates zero; (2) vehicles accelerate or decelerate around the desired space gap most of the time. To explain these phenomena, we propose that, in congested traffic flow, the space gap between two vehicles will oscillate around the desired space gap in the deterministic limit. This assumption is formulated in terms of a cellular automaton. In contrast to FDA and KTPT, the new model does not have any congested steady-state solution. Simulations under periodic and open boundary conditions reproduce the empirical findings of KTPT. Calibrating and validating the model to detector data produces results that are better than that of previous studies.

Influence of Trust and Contract on Dispute Negotiation Behavioral Strategy in Construction Subcontracting

Abstract: This paper examines the effects of trust and contract on the dispute negotiation behavioral strategy of general contractors and subcontractors in construction subcontracting, which is an underresearched area. This research regards trust as a two-dimensional construct, distinguishing the control and coordination functions of contractual governance, and explores their effects on negotiation behavioral strategy; this research also examines the moderating effects of bilateral lock-in. The empirical results from a survey of 272 Chinese general contractors and subcontractors reveal that there is a positive relationship between trust, including both goodwill trust and competence trust, and interest-based negotiation behavioral strategy. However, increasing contractual control will increase the adoption of a rights-based negotiation behavioral strategy, while contractual coordination governance will reinforce the adoption of an interest-based behavioral strategy. Both Chinese general contractors and subco...
