Essay Competition A MARKOV PROCESS BASED DILEMMA ZONE PROTECTION ALGORITHM
نویسندگان
چکیده
Dilemma zone (DZ) is an area at high-speed signalized intersections, where drivers can neither cross safely nor stop comfortably at the yellow onset. The dilemma zone problem is a leading cause for crashes at high-speed signalized intersections and is therefore a pressing issue. This paper presents a novel Markov-chain-based dilemma zone protection algorithm that considers the number of vehicles caught in DZ as a Markov process. Using the vehicle-infrastructure-integration techniques, the new algorithm can predict the numbers of vehicles in DZ with the Markov Chain and determine the best time to end the green so as to reduce the number of vehicles caught in DZ per hour. The algorithm was compared to the traditional green extension system and the results showed that the new algorithm was superior.

Stochastic Methods for Dilemma Zone Protection at Signalized Intersections
Dilemma zone (DZ), also called decision zone in other literature, is an area where drivers face an indecisiveness of stopping or crossing at the yellow onset. The DZ issue is a major reason for the crashes at high-speed signalized intersections. As a result, how to prevent approaching vehicles from being caught in the DZ is a widely concerning issue. In this dissertation, the author addressed s...
متن کاملAn Optimized Advance Detector Configuration for Option Zone Protection at High Speed Signalized Intersections
47 Advance detection and green extension schemes are widely applied in practice as a typical 48 solution to the safety issues associated with the intersection dilemma zone (DZ) problem. Most 49 existing detector configurations were either developed based on the traditional Type I DZ model 50 in which some critical contributing factors were assumed static, or based on generic Type II DZ. 51 A co...
متن کاملModeling Driver Behavior near Intersections in Hidden Markov Model
Intersections are one of the major locations where safety is a big concern to drivers. Inappropriate driver behaviors in response to frequent changes when approaching intersections often lead to intersection-related crashes or collisions. Thus to better understand driver behaviors at intersections, especially in the dilemma zone, a Hidden Markov Model (HMM) is utilized in this study. With the d...
متن کاملEfficient Learning of Multi-step Best Response
We provide a uniform framework for learning against a recent history adversary in arbitrary repeated bimatrix games, by modeling such an agent as a Markov Decision Process. We focus on learning an optimal non-stationary policy in such an MDP over a finite horizon and adapt an existing efficient Monte Carlo based algorithm for learning optimal policies in such MDPs. We show that this new efficie...
متن کاملCooperation, Solution Concepts and Long-term Dynamics in the Iterated Prisoner's Dilemma
Solution concepts help designing co-evolutionary algorithms by interfacing search mechanisms and problems. This work analyses co-evolutionary dynamics by coupling the notion of solution concept with a Markov chain model of coevolution. It is shown that once stationarity has been reached by the Markov chain, and given a particular solution concept of interest, the dynamics can be seen as a Berno...
