Pedestrian Crossing

We analyze the road environment of the present urban main road and the motor vehicle traffic conditions firstly, from which we see that crosswalks should be added and some intersections should be signal control optimized. Then using the timing linear control system theory which is suitable for China, the paper optimizes the crosswalk and intersection signal timing. Simulation is conducted with simulation software of VISSIM in the end, obtaining that after arterial road coordination, although a crosswalk is added in optimized arterial road, the total stop delay and the travel time of the mainstream vehicles are effectively reduced. The program satisfies the need for pedestrian crossing, and obtains better green wave band of arterial road.

Modelling Process

Puffin crossing is the most recent signalised crossings in UK. The operation of Puffin signal control is mainly based on traffic condition hence could impose longer waiting time on pedestrian. Therefore there is a need to review on the operation of the signal control strategy of Puffin crossings to make it more pedestrian responsive without imposing significant delay to other road users. Research to date has shown that VISSIM model is more suitable for the evaluation of signal control improvement.  The latest signal controlled pedestrian crossing facility, the Puffin, has been modelled and tested in VISSIM micro-simulation model. The objective of this study is to verify the Puffin coding using VISSIM microsimulation software. It is to ensure that the Puffin signal control in VISSIM is working as in a real traffic condition. For this purpose a suitable mid-block section was selected at Market Street, United Kingdom. Pedestrians' characteristics, vehicular characteristics, geometric layout of the site were retrieved from video recording. All these characteristics were coded in Puffin model using VISSIM micro-simulation. The results proved that the Puffin model in VISSIM is able to reproduce site representative condition.  The findings in this study are significant in the whole modelling process.

Pedestrian Crossing

Pesatnya pertumbuhan lalu lintas saat ini khususnya kendaraan roda dua, menyebabkan minimnya pergerakan lalu lintas non-motorized seperti pengguna sepeda serta pejalan kaki. Tingginya aktivitas lalu lintas motorized menyebabkan sulitnya seseorang mendapatkan kesempatan (gap) untuk menyeberang jalan. Penelitian ini dilakukan pada ruas jalan dengan tata guna lahan untuk pendidikan dan pertokoan di sekitar jalan UGM, Yogjakarta. Metode yang digunakan dalam penelitian ini adalah statistik deskriptif dengan variabel gap yang digunakan kendaraan, kecepatan menyeberang dan kecepatan kendaraan. Untuk lokasi I (pendidikan) penyeberang tunggal rata-rata waktu gap kendaraan yang dibutuhkan maksimal adalah 20 detik, sedangkan penyeberang kelompok, waktu gap kendaraan yang dibutuhkan adalah 23 detik, untuk rata-rata kecepatan menyeberang pada penyeberang tunggal maksimal 5 m/detik sedangkan penyeberang kelompok arah selatan 6,04 m/detik, serta kecepatan kendaraan pada saat terdapat penyeberang tunggal rata-rata maksimal adalah 20,48 km/jam, sedangkan untuk penyeberang kelompok maksimal adalah 25,87 km/jam untuk jarak menyeberang 13 m. Untuk lokasi II (pertokoan) penyeberang tunggal rata-rata waktu gap kendaraan yang dibutuhkan maksimal adalah 18,48 detik, sedangkan penyeberang kelompok, waktu gap kendaraan yang dibutuhkan adalah 25 detik, untuk rata-rata kecepatan menyeberang pada penyeberang tunggal maksimal 4,5 m/detik, sedangkan penyeberang kelompok arah utara 7,35 m/detik serta kecepatan kendaraan pada saat terdapat penyeberang tunggal kecepatan rata-rata kendaraan maksimal adalah 20,48 km/jam, sedangkan untuk penyeberang kelompok maksimal adalah 26,60 km/jam untuk jarak menyeberang 14 m. Dari hasil analisis waktu gap kendaraan, kecepatan menyeberang dan kecepatan kendaraan yang dibutuhkan penyeberang untuk penyeberang tunggal lebih tinggi dibandingkan dengan penyeberang secara berkelompok.

Along with urbanism and rapid motorization in the Pidie district leads to increasing private-mode dependency. Increasing number of the vehicle used in urban road networks could affect the pedestrian crossing facilities, especially within the school zone. Therefore, this study aims to evaluate the needs for pedestrian crossing facilities within school zone located at Prof. A. Majid Ibrahim Road in the Pidie District. The gap acceptance approach is used to evaluate accepted and rejected gaps. Furthermore, the effectiveness of the pedestrian crossing (Zebra Cross) regarding whether it is truly appropriate or not then evaluates using the statistical method of hypothesis testing. The analysis result reveals that the higher speed in the traffic, the greater gap required by crosser. The average speed for the traffic direction of Medan - Banda Aceh is about 47,13 km/h; pedestrians require the distribution of gap value of 85% or about 7 m crossing distance is necessary to available. At the location of the zebra cross 1, in the morning and noon observations show the average gap is about 7.71 and 9.18 seconds, respectively. Furthermore,  as for the location of the zebra cross 2, in the morning and noon observations show the average gap is about 8.69 and 10.20 seconds, respectively. Based on the gap distribution, it concluded that the zebra cross facility at Prof. A. Majid Ibrahim Road is still worth using. As for the effectiveness of zebra cross, based on 85% speed at a distance from 50 m and 30 m can be concluded that zebra cross at Prof. A. Majid Ibrahim Road is ineffective. The absence of a decreasing in vehicle speed as it passes through the zebra cross, the velocity of the vehicle at 50 m from the zebra cross ≥ 30 m from the zebra cross. The speed of the vehicle tends to be stable at the time of going through the zebra cross.

The pedestrian is an integral element in the urban road infrastructure. Extreme vehicle heterogeneity, poor lane discipline, lack of adequate infrastructure, and road users’ poor understanding of the right-of-way and yielding make Indian roads extremely dangerous for pedestrians, especially at intersections. Since motorists, in general, do not yield to pedestrians at unsignalized intersections, pedestrians are forced to wait. When the waiting time exceeds a particular threshold, a pedestrian may attempt an unsafe crossing by accepting rolling gaps. The motivation behind this research paper was to understand the effect of waiting time on pedestrian rolling gap acceptance behavior at unsignalized intersections in India under heterogeneous traffic. This paper presents a study on pedestrian crossing behavior at unsignalized intersections in an urban traffic environment that used the survival analysis approach. The field data were collected from six sites in the city of Kanpur, India. The results show that rolling gap acceptance behavior is affected by various factors, such as pedestrian demographic characteristics, approaching vehicle features, and pedestrian group composition. Male pedestrians behave more aggressively and undertake unsafe street crossings. When pedestrians are part of a group, they do not accept rolling gaps easily. One interesting finding of the study is that when the approaching vehicle type is a two-wheeler or when vehicles are not in a platoon, the probability of accepting a rolling gap decreases.
