“…A study has been made to see the effect of neighboring leading vehicle's position on the following vehicle in a staggered car-following. Attempts have also been made to incorporate the staggered car-following behavior using the visual angle concept by Jin et al [17,18], but these approaches do not adequately represent the lateral discomfort. Recent study by Pal and Mallikarjuna [19] used effective width of vehicles (which also included LC maintained by vehicles) to calculate macroscopic parameter of area occupancy of traffic.…”

Heterogeneous traffic conditions prevail in developing countries. Vehicles maintain weak lane discipline which increases lateral interactions of vehicles significantly. It is necessary to study these interactions in the form of maintained lateral gaps for modeling this traffic scenario. This paper aims at determining lateral clearances maintained by different vehicle types while moving in a heterogeneous traffic stream during overtaking. These data were collected using an instrumented vehicle which runs as a part of the stream. Variation of obtained clearance with average speed of interacting vehicles is studied and modeled. Different instrumented vehicles of various types are developed using (1) ultrasonic sensors fixed on both sides of vehicle, which provide inter-vehicular lateral distance and relative speed; and (2) GPS device with cameras, which provides vehicle type and speed of interacting vehicles. They are driven on different roads in six cities of India, to measure lateral gaps maintained with different interacting vehicles at different speeds. Relationships between lateral gaps and speed are modeled as regression lines with positive slopes and beta-distributed residuals. Nature of these graphs (i.e., slopes, intercepts, residuals) are also evaluated and compared for different interacting vehicle-type pairs. It is observed that similar vehicle pairs maintain less lateral clearance than dissimilar vehicle pairs. If a vehicle interacts with two vehicles (one on each side) simultaneously, lateral clearance is reduced and safety of the vehicles is compromised. The obtained relationships can be used for simulating lateral clearance maintaining behavior of vehicles in heterogeneous traffic.

The aim of this paper is to study the car following model in one-line road with uniform vehicles. The model which is used in this paper is called the full velocity difference model (FVDM). This model is a modified model of optimal velocity model (OVM). The algorithm of the FVDM will be elaborated in detail. Some numerical experiments are given in order to see the behaviour of the model. In the numerical simulation, the steady state position of cars is obtained at time t = 10 s with initial positions 53, 46.5 and 22 meters for three vehicles. I. PENDAHULUANKemacetan merupakan salah satu masalah besar pada dinamika lalu lintas, dimana faktor paling berpengaruh yang dapat menyebabkan kemacetan lalu lintas adalah peristiwa kecelakaan dalam lalu lintas. Jika dalam suatu lalu lintas terjadi peristiwa kecelakaan antar kendaraan, maka iringan kendaraan tidak akan terjadi dalam lalu lintas tersebut. Salah satu faktor yang juga mempengaruhi kekacauan lalu lintas seperti kecelakaan dalam sebuah iringan kendaraan di lalu lintas adalah perilaku pengendara. Jarak antar kendaraan yang terlalu kecil dan tidak sebanding dengan besarnya kecepatan kendaraan.Setiap pengendara memiliki keinginan untuk mengatur kecepatan, posisi kendaraan dan menentukan waktu kapan melakukan perlambatan maupun percepatan berdasarkan jarak minimum dengan kendaraan depannya dan waktu [3], [4], [7]. Penelitian ini menyimulasikan dan menganalisis suatu iringan kendaraan dalam satu jalan yang lurus dan satu lajur dengan pendekatan metode full velocity diference model atau yang lebih dikenal dengan FVDM. Model FVDM bertujuan untuk menyimulasikan iringan kendaraan dengan mengoptimalkan dan mengamati kecepatan, waktu dan jarak dengan mempertimbangkan parameter variabel fungsi langkah dan selisih antar kecepatan.

“…He improved a stopping distance based approach that was proposed by Gipps (1981), and presented a new car-following model, taking into account lateral friction between vehicles. Jin et al (2010) proposed a non-lane-based car following model using a modified fullvelocity difference model. All the above models have assumed that drivers are able to perceive distances, speeds, and accelerations.…”

Signalized intersections are vital nodal points in a transportation network and their efficiency of operation greatly influences the entire network's performance. Traffic simulation models have been widely used in both transportation operations and traffic analyses because simulation is safer, less expensive, and faster than field implementation and testing. This study assessed performance indication measures at Amakom intersection using micro simulation models in Synchro/SimTraffic. Traffic, geometric and signal control data including key parameters with greatest impact on the calibration process were collected on the field. At 5% significant level, the Chi square test and t-test analyses revealed that headway had a strong correlation with saturation flow compared to speed for both field and simulated conditions. It was concluded that changes in phasing plan with geometric improvement would improve upon the intersection's level of service.
