Traffic Delay

A crossing is a meeting point between roads and railways, where this often causes delays and traffic queues, as happened at the crossing on Jl. Abimanyu, Tegal City. This study aimed to analyze the volume, delay and queue length of traffic on each road which occured due to the closing of the railroad crossing. Apart from that, this research was also intended to provide reasonable alternative input for both the management of Pertamina and the road users. This research used the analysis method of v/c ratio, queue and delay with reference to the Manual for Indonesian Road Capacity. Results of the analysis show, the  highest queue occurred on the Abimanyu road, which was of 70.5 pcu with the delay of 581.5 seconds/pcu. On the segment of Jl. Menteri Supeno I, the traffic queue was reported to have reached 47.8 pcu with the delay time of 441 seconds/pcu; on the segment of Jl. Semeru, the queue was reported to reach 17 pcu with the delay of 395.6 seconds/pcu, and the last one was the queue at the segment of Jl. Menteri Supeno II which was of 10.8 pcu, with the delay time of 368.5 seconds/pcu. Ones of the keys to overcome problems of traffic queues and delay were by dividing the shunting time into 2 phases according to the results of alternative analysis II where the traffic queue became smaller of 35.3 pcu with the delay time of 290 seconds/pcu and by changing the shunting schedule at off peak time.

AbstractCongestion is a problem in transportation that most occurs on urban roads. The increase in the number of vehicle that are not matched by an increase in road capacity makes the volume of vehicle that cross the road exceeds the existing road capacity causing congestion. Besides increasing the number of vehicle, one of the causes of congestion was the existence of U-Turns. The poor design and management of U-Turns will cause drivers to be disorganized when turn around and causing congestion. Factors that cause congestion on the U-Turns include delay and length of queue. This research was conducted with multiple linear regression methods with data in the form of traffic surveys  and road geometry. The results of multiple linear regression analysis mentioned that the vehicle delay time on the U-Turn movement was caused by the turning volume and the median aperture width with the  dominant factor is the median aperture width. Then, the length of queue on the U-Turn movement is caused by the delay time and the turning time with the dominant factor is the turning time. Keywords : congestion, length of queue, delay time, U-Turn AbstrakKemacetan merupakan suatu permasalahan dalam transportasi yang sering terjadi di jalan perkotaan. Peningkatan jumlah kendaraan yang tidak diimbangi dengan peningkatan kapasitas jalan membuat volume kendaraan yang melintasi ruas jalan tersebut melebihi kapasitas jalan yang ada sehingga menyebabkan kemacetan. Selain peningkatan jumlah kendaraan, salah satu penyebab kemacetan adalah adanya U-Turn. Desain dan pengelolaan U-Turn yang kurang baik akan menyebabkan tidak teraturnya pengendara yang akan memutar arah sehingga menimbulkan kemacetan. Faktor yang menyebabkan kemacetan pada U-Turn diantaranya adalah  tundaan dan panjang antrian. Penelitian ini dilakukan dengan metode analisis regresi linier berganda dengan data berupa survei lalu lintas dan geometrik jalan. Hasil analisis regresi linier berganda menyebutkan bahwa waktu Tundaan kendaraan pada pergerakan U-Turn dipengaruhi oleh adanya Volume Putar Balik kendaraan dan Lebar Bukaan Median dengan faktor dominan berupa Lebar Bukaan Median. Kemudian Panjang Antrian pada pergerakan U-Turn dipengaruhi oleh waktu Tundaan dan Waktu Putar Balik dengan faktor dominan berupa waktu Putar Balik. Kata Kunci: kemacetan, panjang antrian, tundaan, U-Turn.

The road users usually suffer from several kinds of congestion and delay especially at intersections. The traffic flow congestion due to increasing traffic volumes can be decreased by implementing some suitable alternative designs of interchanges such as Diverging diamond interchange (DDI) and conventional diamond interchange (CDI). In this study, a comparison between the DDI and CDI in traffic conditions in Riyadh city is conducted. The analysis involved different measures of effectiveness that includes delay, queue length, and number of stops. In this context, each interchange type was evaluated for traffic volumes at certain peak hours using micro-simulation program named as “Synchro.” The finding of this study shows that DDI provides a better result when compared with CDI in terms of delay, queue length and number of stops. The control delay for the DDI is approximately one third of the CDI. Also, the queue length for the DDI is about one half of the CDI. Furthermore, the number of stops for the DDI is as one half as the CDI.

Abstract: This research aims to analyze the impact of Janti Flyover Construction toward the growth of layout at Janti Urban Area, including structured space, open space, and linkage. Method used for data collecting are observation, air photograph monitoring, and interview, whereas the analysis method is qualitative description, which is the superimposed method of two layers, that are the layout condition before and after flyover construction. The result shows that the impact of Janti Flyover construction can be seen on building mass (solid), the increasing number of open spaces, including the road network, parking place, and park, whereas the relation between spaces, visually and structurally, can be seen on the growth of buildings which have new shapes and styles, therefore the performance of the overall building does not have a proportional shape. Considering Janti Street at the collective relation, its role is getting stronger as the main frame road network.Keywords: Flyover construction, layout changing, Janti AreaAbstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pembangunan Jalan Layang Janti terhadap perkembangan tata ruang Kawasan Janti, meliputi ruang terbangun, ruang terbuka, serta hubungan antar ruang (“linkage”).

Real or perceived traffic risk is a significant barrier to walking and cycling. To understand whether similar barriers influence equestrians, this study obtained exercise behaviours, road use and experiences of road-related incidents from UK equestrians (n = 6390) via an online questionnaire. Multivariable logistic regression models were used to identify factors associated with road use and experiencing a near-miss or injury-causing incident in the previous year. Content analysis identified themes around equestrians’ decisions not to use roads. Our results show that most equestrians (84%) use roads at least once weekly, and in the previous year, 67.7% had a near-miss and 6.1% an injury-causing incident. Road use differs regionally, with exercise type and off-road route availability. Road-using equestrians covered greater daily distances and were younger. However, younger equestrians were at higher risk of near-misses. Respondents’ decisions not to use roads were based on individualised risk assessments arising from: the road itself, perceptions of other road users, the individual horse and the handler’s own emotional management. Roads were perceived as extremely dangerous places with potentially high conflict risk. Injury-causing incidents were associated with increasing road-use anxiety or ceasing to use roads, the proximity of off-road routes, having a near-miss and type of road use. Targeted road-safety campaigns and improved off-road access would create safer equestrian spaces.

Group Characteristics

So far, research on pedestrians’ gaze behavior while crossing roads has mainly focused on individual pedestrians rather than groups. However, pedestrians often travel in groups especially in downtown areas. This observational study investigated how group characteristics (group size and movement of the group), situational factors (presence of traffic), and demographic variables (age and gender) influence pedestrians’ gaze behavior towards traffic during road crossing. A total of N = 197 pedestrians were observed of whom n = 24 traveled alone, n = 128 traveled in groups of two or three, and n = 45 traveled in groups of four or more. Results indicated that with increasing group size, the odds to observe traffic decreased. Diffusion of responsibility among group members might explain this effect. Finally, pedestrians’ group characteristics should be considered when developing automated vehicles that interact with vulnerable road users.

In this paper, an ultrawideband localization system to improve the cyclists’ safety is presented. The architectural solutions proposed consist of tags placed on bikes, whose positions have to be estimated, and anchors, acting as reference nodes, located at intersections and/or on vehicles. The peculiarities of the localization system in terms of accuracy and cost enable its adoption with enhanced risk assessment units situated on the infrastructure/vehicle, depending on the architecture chosen, as well as real-time warning to the road users. Experimental results reveal that the localization error, in both static and dynamic conditions, is below 50 cm in most of the cases.

Fourier Series Analysis

A simple analysis to derive Branston’s generalized queueing model for (time-) headway distributions is presented. It is assumed that the total headway is the sum of two independent random variables: the empty zone and the free-flowing headway. The parameters of the model can be used to examine various characteristics of both the road (e.g., capacity) and driver-vehicle combinations (e.g., following behavior). Furthermore, the model can be applied to vehicle generation in microscopic simulation models and to safety analysis. To estimate the different parameters in the model, a new estimation method is proposed. This method, which was developed on the basis of Fourier-series analysis, was successfully applied to measurements collected on two-lane rural roads. The method was found to be both computationally less demanding and more robust than traditional parameter techniques procedures, such as maximum likelihood. In addition, the method provides more accurate results. Parameters in the model were examined with the developed estimation method. Estimates of these parameters at a specific period and a specific measurement location were to some extent transferable to other periods and locations. Application of the method to road capacity estimation is discussed.
