A mathematical model of a free piston linear engine is established. The motion characteristics as well as the natural frequency map of the free piston are established. Then, its motion characteristics are successfully explained from the oscillation point. The full simulation model is built up in...

This paper proposes a Monte Carlo model to estimate pedestrian delays at signalized intersections adopting pre-timed two-phase control in developing cities like Xi’an, China. In the model, the signal cycle is divided into a series of subphases, and each subphase lasts 1s. The model includes...

The co-gasification behavior of deoiled asphalt (DOA) with coal and biomass were investigated by a thermogravimetric analyzer (TGA). The gasification experiments were conducted under CO2 atmosphere within an isothermal temperature range from 900 to 1100°C. The physical properties of the samples...

In many Chinese cities, pedestrian's road crossing behavior is different from that of pedestrians in developed countries. This paper presents a pedestrian model for traffic system micro-simulation in China. Considering the high rate of signal non-compliance, we classify pedestrians into two...

This paper proposes a pedestrian delay model suitable for signalized intersections in developing cities, on the basis of a field study conducted in Xi'an, China. The field study consisted of two parts: Part I involved only one crosswalk, and the signal cycle was divided into 13 subphases; Part...
