PEDESTRIANS CHARATERISTICS AT TRAFFIC LIGHT SIGNAL INTERSECTION IN IPOH

Pedestrian crossing is one of the greatest challenges for the traffic and safety engineering communities. Lack of facilities for pedestrian caused fatal accidents involving pedestrians especially at intersections where there is high volume of vehicles. Many major roads in Malaysia are ignoring the facilities for pedestrian to cross the road. Therefore, many pedestrians risk their live to cross the roads even though they knew the danger and risk they have to take. Concerning pedestrian fatality at intersection, nowadays a lot of facilities for pedestrians have been provided in order to increase the safety of pedestrian at signalized intersection. These include the pedestrian crossing lane, traffic system for pedestrians and provided safe place for pedestrian to cross the road. By adding facilities at traffic light signal, the delays for vehicle will be higher and this can caused heavy congestion. On the other hand, if the delays time for pedestrian is high, the possibility of non-compliance pedestrian will increase. This project studied the characteristic of the pedestrians in term of delays and compliancy at two selected signalized intersections. Traffic survey was conducted to study the performance of the traffic signal with the existence of pedestrian facilities at the two intersections selected. Two types of traffic signal for pedestrians were used namely pushbutton system which located at Jalan Sultan Yusuf and fixed-time system which located at Jalan Dato Onn Jaafar- Jalan Sultan Idris Shah. The performance of the road as well as performance of pedestrian crossing was analyzed using SIDRA software. Finally, recommendations on how to improve the intersection were proposed. The average walking speed for pedestrian is 1. 6 m/s for free-flow walking. The average walking speed is 1.28 m/s and 1.56 m/s for both traffic systems. It can be concluded that the average walking speed at the intersections is quite normal. Non-compliance pedestrians at the intersection are quite low at both sites. For Jalan Sultan Yusuf, the LOS for pedestrian is B while for vehicle is D. For Jalan Dato Onn Jaafar- Jalan Sultan Yusuf the LOS for pedestrian and vehicle is B and D, respectively

Implementation and Evaluation of a Cooperative Vehicle-to-Pedestrian Safety Application

While the development of Vehicle-to-Vehicle (V2V) safety applications based on Dedicated Short-Range Communications (DSRC) has been extensively undergoing standardization for more than a decade, such applications are extremely missing for Vulnerable Road Users (VRUs). Nonexistence of collaborative systems between VRUs and vehicles was the main reason for this lack of attention. Recent developments in Wi-Fi Direct and DSRC-enabled smartphones are changing this perspective. Leveraging the existing V2V platforms, we propose a new framework using a DSRC-enabled smartphone to extend safety benefits to VRUs. The interoperability of applications between vehicles and portable DSRC enabled devices is achieved through the SAE J2735 Personal Safety Message (PSM). However, considering the fact that VRU movement dynamics, response times, and crash scenarios are fundamentally different from vehicles, a specific framework should be designed for VRU safety applications to study their performance. In this article, we first propose an end-to-end Vehicle-to-Pedestrian (V2P) framework to provide situational awareness and hazard detection based on the most common and injury-prone crash scenarios. The details of our VRU safety module, including target classification and collision detection algorithms, are explained next. Furthermore, we propose and evaluate a mitigating solution for congestion and power consumption issues in such systems. Finally, the whole system is implemented and analyzed for realistic crash scenarios

CONTRIBUTING OF LOCAL AREA TRAFFIC MANAGEMENT TO REDUCE ENVIRONMENTAL IMPACTS IN SURABAYA

There has been a consistent interest at both the metropolitan scale and at the local level to reduce energy consumption, relieve traffic congestion, enhance the mobility of central business areas, promote pedestrian and bicycle use. Over several years, a large amount of event relevant to local area planning in Surabaya has been required. A few considerable topics of planning, such as pedestrian movement facilities, bicycle lane planning, connected public transportations facilities, and the traffic management that are particularly applicable to local area planning and design in certain area of Surabaya especially with some objective to reduce environmental impacts such as traffic noise and air pollution. Designing the integrated plan of an environmental impact attenuation together with pedestrian lane such as buffer zone, planting vegetation and noise barriers can expected to minimizing those impacts

Multiagent Systems in Automotive Applications

The multiagent systems have proved to be a useful tool in the design of solutions to problems of distributed nature. In a distributed system, it is possible that the data, the control actions or even both, be distributed. The concept of agent is a suitable notion for capturing situations where the global knowledge about the status of a system is complex or even impossible to acquire in a single entity. In automotive applications, there exist a great number of scenarios of distributed nature, such as the traffic coordination, routes load balancing problems, traffic negotiation among the infrastructure and cars, to mention a few. Even more, the autonomous driving features of the new generation of cars will require the new methods of car to car communication, car to infrastructure negotiation, and even infrastructure to infrastructure communication. This chapter proposes the application of multiagent system techniques to some problems in the automotive field
