Traffic jam mainly first appears at the oversaturated intersections, so signal control strategy of the oversaturated intersection will directly affect the quality of traffic system. The QUEUE ...strategy for an isolated oversaturated intersection is proved to be effective. But under the control of QUEUE strategy, the secondary road is easy to overflow in a real situation. According to this reason, an indicator of spillover risk is proposed in this paper firstly. Then a dual-objective optimal control proposition is established which consists of shortest oversaturation duration and lowest spillover risk. In the QUEUE space, a Time Risk Optimal Trajectory(TROT) can be found. The numerical solution shows that the trajectory approximates a straight line. Based on TROT, a PID method is adapted to control the intersection state point to the optimal trajectory, and a TROT-based PID control method(TROT-PID) is established. Experiments show that the TROT-PID reduces the road overflow probability and is more suitable for intersections with large fluctuating traffic.
Queue length of vehicles due to stopping of a public vehicle, cause traffic jam. To relate the influence of vehicle volume, by effective width of the road and public vehicle’s stopping time to queue ...length, linear regression model is used. The result of analysis by states that the best solution to reduce the queue length of vehicle is controlling the public vehicle to stop at the right place and setting a limit of stopping time. Abstract in Bahasa Indonesia : Panjangnya deretan kendaraan jalan raya akibat berhentinya angkutan umum adalah salah satu bentuk kemacetan di jalan raya. Analisa pengaruh panjang antrian ini terhadap volume kendaraan yang lewat, lebar efektif jalan dan waktu henti angkutan umum, menggunakan metode pendekatan dengan cara regresi linier. Hasil analisa mendapatkan solusi yang terbaik berupa penertiban angkutan umum agar berhenti pada tempatnya dan dengan cara yang benar, sekaligus pembatasan lamanya waktu berhenti angkutan kota. Kata Kunci: lebar efektif, panjang antrian, volume kendaraan, waktu henti kendaraan umum

The Akerviks shopped for their park model with their friends, the McCanns, and ultimately bought adjacent lots. Even after paying for their "cabins" and lots, they had enough money left over to ...eventually add decks and landscaping to improve their lots and buy golf carts to cruise around the campground. Plus, they're crossing their fingers that the value of the lots will increase and eventually they'll be able to apply that equity toward the four- season cabins they've always wanted. "Most campgrounds will close and turn into condos or residential property," said Duane Hoverstein, owner of Gull Lake Campground, near Bemidji. Hoverstein recently converted a portion of the resort into "Summer Haven on Gull," which will have 95 RV lots for sale and he plans to add about 70 more. In April Robert Quene bought an Airstream and a lot at the park, 45 minutes north of his home in the Twin Cities. For about $20,000, he bought a 2003 Bambi, the smallest model in Airstream's lineup. He paid less than $3,000 for his share at the park, which also operates as a cooperative, and he pays a monthly association fee.
This paper studies a generalization of the GI/G/1 queueing system in which there is a random ‘set-up’ time for customers who arrive when the server is idle. Mathematical methods are given for finding ...various transient characteristics of the system.
The mythographer Ptolemy Chennus (Phot. Bibl. 190) wrote a strange work full of fictive stories and among these are several anecdotes of ancient sport. Ptolemy was another Graeco-Roman intellectual ...who in the Roman Empire revalued the Greek past, including physical education and sports, because they were part of the paideia and an operator of Greek identity at least until Hellenistic times.
