A DMB-TCA Simulation Method for On-Road Traffic Travel Demand Impact Analysis
نویسندگان
چکیده
Travel Demands influence micro-level traffic behavior, furthermore traffic states. In order to evaluate the effect of travel demands on traffic states, this paper introduces the DemandMotivation-Behaviors (DMB) micro traffic behavior analysis model which denotes that vehicles behaviors are determines by motivations that relies on traffic demands from the perspective of behavior science. For vehicles, there are two kinds of travel demands: reaching travel destinations from orientations and meeting expectations of travel speed. To satisfy travel demands, the micro traffic behaviors are delivered such as car following behavior, optional and mandatory lane changing behaviors. Especially, mandatory lane changing behaviors depending on travel demands take strong impact on traffic states. In this paper, we define the DMB-based cellular automate traffic simulation model to evaluate the effect of travel demands on traffic states under the different δ values that reflect the ratio of mandatory lane-change vehicles. Keywords—Demand-Motivation-Behavior, Mandatory Lane Changing, Traffic Cellular Automata.

Literature Review of Traffic Assignment: Static and Dynamic
Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...

Road traffic accidents are the leading cause of death in international travelers. With the growth of international travel, the number of visitors who rent a vehicle upon arrival at their destination by air or by sea is expected to increase. Jet lag is a well-recognized maladaptation to international travel across multiple time zones. Little is known about the possible influence of jet lag sympt...
متن کاملAn Iterative Algorithm to Determine the Dynamic User Equilibrium in a Traffic Simulation Model
An iterative algorithm to determine the dynamic user equilibrium with respect to link costs defined by a traffic simulation model is presented. Each driver's route choice is modelled by a discrete probability distribution which is used to select a route in the simulation. After each simulation run, the probability distribution is adapted to minimize the travel costs. Although the algorithm does...
متن کاملImprovement of Conventional Traffic Signaling Device - Self Routing Traffic Light System
Traffic congestion becomes a serious issue nowadays especially at urban cities area. When road users come at the intersection point, there is always a conflict “who can go first” on their mind. Due to the high volume of vehicles on the road, intersection points need a traffic signaling device to control the traffic flow. That is the reason traffic signalling device is installed at most of the i...
