Vehicles have become a daily needs for all of us and it is normal that every family is having at least one vehicle at their home. This leads to the increased of accidents and vehicular ad hoc network (VANET) is an approach invented to tackle with this problem. In order to study the algorithm in VANET, a mobility simulator is needed for simulation. SUMO is proved to be a good simulation tool for VANET...
Urban congestion in major cities of Malaysia is getting severe over decades with increasing active vehicles and travelling time on the road.

Traffic data obtained from surveillance system has been vital for traffic operators to monitor the traffic flow at a traffic intersection. However, detailed information of the traffic flow such as the behavioural manoeuvres is not sufficiently provided by the inductive-loop traffic detectors. Thus, vehicles trajectory dataset is selected as traffic data input in traffic simulation for modelling the...
Relieving traffic congestion is an urgent call for traffic engineering. Although various adaptive control strategies have been reported in literature to reduce the travel delay, most of them are not tested under oversaturated condition, where the traffic demand is higher than the road capacity. Therefore, this work proposes genetic algorithm (GA) to optimize the traffic signals for reducing the average...
The development of an efficient traffic flow monitoring system has been the main focus for many researchers working in the field.

With the emerging video based surveillance system, vehicle trajectory can be extracted for observation and...
Non-destructive testing in structural inspection is a list of techniques that is used to evaluate the condition of a structure in order to determine whether cracks, flaws defects or damages occur in structural build without causing any damage to the test object. This work presents the characterization study of using acoustic signals for underwater non-destructive testing. The optimum operating frequency...
Increment of on-road vehicles has urged public venues to provide visitors with a larger area of parking space. As the parking area grew larger for example in a hyper mall, a well-organized parking management system is necessary to assist drivers in locating parking position. Besides, it can also help the management team to monitor vehicle flow in the parking lot. Vehicle tracking plays an important...
Network coding combines several packets from different sources and broadcasts the combined packet to several destinations in single transmission time slot. Each destination is capable to extract the intended information by decoding from a common packet. In short, network coding improves the throughput for wireless and wired networks but also causes side effects such as complexity of packets management...
