“…This may be explained as the weakness of enforcement using fix speed camera [ 37 ]. For experienced taxi drivers, they usually avoid punishment by slowing down near the camera and fiercely accelerate after the pass, which is known as "kangaroo effect" [ 38 , 39 ]. However, this phenomenon can be captured by processing GPS trajectory, and thus, identified more practical serious speeding on the downstream area of speed camera.…”

Speeding behavior, especially serious speeding, is more common in taxi driver than other driving population due to their high exposure under traffic environment, which increases the risk of being involved in crashes. In order to prevent the taxi and other road users from speed-related crash, previous studies have revealed contributors of demographic and driving operation affecting taxi speeding frequency. However, researches regarding road factors, and spatial effect are typically rare. For this sake, the current study explores the contributions of 10 types of road characteristics and two kinds of spatial effects (spatial correlation and spatial heterogeneity) on taxi total speeding and serious speeding frequency. Taxi GPS trajectory data in a Chinese metropolis were used to identify speeding event. The study then established four kinds of Bayesian hierarchical count models base on Poisson and negative binominal distribution to estimate the contributor impacts, respectively. Results show that Bayesian hierarchical spatial Poisson log-linear model is optimum for fitting both total and serious speeding frequency. For the analysis, it is found that drivers are more likely to commit speeding on long multilane road with median strip, and road with non-motorized vehicle lane, bus-only lane and viaduct or road tunnel. Roads with low speed limit, and work zone are associated with increasing speeding as well. In terms of serious speeding, bus-only lane is not a contributor, while road speed camera number and one-way organization are significantly positive to the speeding frequency. Furthermore, it reveals that two spatial effects significantly increase the occurrence of speeding events; the impact of spatial heterogeneity is more critical.

“…Therefore, in order to ensure the practicability of this study, the sunny day with better weather was selected for the experiment. During the experiment, the driver passed through the Jiaozhou Bay undersea tunnel at an ordinary speed of 70 km/h without changing lanes within the undersea tunnel [37]. When the driver sensed the critical points between the entrance and middle sections of the undersea tunnel and those between the middle and exit sections of the undersea tunnel, he/she reported them to the assistant experimenter, who was the copassenger, in real time.…”

At present, there is no standard or research to define the specific length of the entrance and exit sections of an undersea tunnel. In combination with the unique longitudinal slope of the undersea tunnel and the change in the illumination difference, the lengths of the lane change, transition and adaptation sections of the entrance and exit sections of the undersea tunnel were theoretically deduced, and a model for the entrance and exit sections lengths was established. Considering the Qingdao Jiaozhou Bay undersea tunnel as an experimental subject, the accuracy of the model of the entrance and exit section lengths was verified using two methods. The results indicated that the lengths of the entrance and exit sections of undersea tunnels change with changes in the factors such as the illumination, vehicle speed, and slope. In the case of the Qingdao Jiaozhou Bay undersea tunnel, when the vehicle passes the undersea tunnel at a speed of 70 km/h on a sunny day, according to the studied model, the entrance and exit sections of the undersea tunnel are 146.7 m and 157.1 m long, respectively. The entrance and exit section lengths of the undersea tunnel, determined using test method 1 and test method 2 are 151.0m, 153.6m and 161.0m, 148.9m, respectively. The absolute errors between the results of the model and test method 1 and 2 are less than 10%. These findings indicate that the model for the entrance and exit section lengths of undersea tunnels is reasonably accurate.

The installation of transverse rumble strips (TRS) is a common practice to reduce vehicle speed and alert drivers on the roadway. However, the combination of TRS with road studs to enhance traffic safety is still not widely used by local authorities. This paper aims to evaluate the effectiveness of and the public perception about the installation of TRS with road studs. A field observation was carried out on the TRS road section with and without road studs for speed evaluation. A questionnaire survey was also conducted to assess the public perception towards the installation of this measure. The results indicate that the mean speed at the TRS road section with road studs was lower than the speed at the TRS road section without a road stud and its effectiveness was evaluated using a statistical test. Responses from the questionnaire survey showed that respondents agree that both TRS with and without road studs can reduce speed effectively. Respondents also believed that the installation of road studs might cause damage to the vehicle. This paper concludes that TRS installed with road studs effectively reduces speed which is consistent with the results of the public perception survey.
