Summary Bus travel time reliability performance influences service attractiveness, operating costs, and system efficiency. Better understanding of the distribution variability is a prerequisite for analysis. A wide array empirical studies has been conducted to model times in transport. However, depending on data tested approaches applied examine fitting performance, different conclusions have reported. This paper aims specify most appropriate day‐to‐day by using novel evaluation approach set...
Transit agencies increasingly deploy planning strategies to improve service reliability and real-time operational control mitigate the effects of travel time variability. The design such can benefit from a better understanding underlying causes Despite significant body research on topic, findings remain influenced by approach used analyze data. Most studies use linear regression characterize relationship between covariates in context central tendency. However, many applications, actual...
Control at railway level crossings, using either road rumble strips or in-vehicle auditory warning devices, has the potential to improve safety. This article evaluates driver behavior of these two devices and conventional crossing (flashing lights a stop sign) driving simulator. Rumble have been seen encourage drivers reduce speed earlier on approach but did not affect stopping compliance. In-vehicle warnings produced high compliance and, overall, comparable that for flashing lights....
The asphalt pavement construction monitoring system presented in this paper covers two main processes: hot mix (HMA) plant production and the laydown compaction operation. architecture of system, development required hardware software structure, implementation process are paper. is able to perform automatic data collection transmission, can automatically provide feedback site for real-time quality control. entire works without much human intervention project throughout period real time. was...
There is a need to match emission estimations accuracy with the outputs of transport models. The overall error rate in long-term traffic forecasts resulting from strategic models likely be significant. Microsimulation models, whilst high-resolution nature, may have similar measurement errors if they use obtain demand predictions. At microlevel, this paper discusses limitations existing emissions estimation approaches. Emission for predicting pollutants other than CO 2 are proposed. A genetic...
To estimate traffic facility-oriented particulate matter (PM) emissions, emission factors are both necessary and critical for planners the community of professionals. This study used locally calibrated laser-scattering sensors to collect PM concentrations in a tunnel. Emission light-duty heavy-duty vehicles were found be higher autumn compared summer. Based on this study’s data analysis, terms mass, have strong seasonal effect. The also conducted composition test normal days during haze...
The acceleration profile of leading vehicles at intersections is critical for emission estimation and microlevel queue simulation. Data obtained from experiments using a high-resolution driving simulator can deliver useful insights into microscale behaviors signalized intersections. Acceleration data the in queues are collected by simulator. observed accelerations found to be stochastic. characteristics also significantly diversified among participants. Hence, Markov chain implemented...
Abstract This article presents an integrated educational module for undergraduate traffic engineering at the microscale level. When dealing with a complex transportation system, education program should cultivate students’ acquisition of both in‐depth specialization and breadth knowledge. For instruction signal phase design, this design that includes several subjects: circuits electronics, object‐oriented programming (OOP). Due to lengthy evolution high‐end industrial standards issue,...
This paper presents a solution to detect pedestrian and vehicle using 16-line LIDAR. Unlike prior researches, the downward-looking LIDAR is mounted on bridge over road lanes instead of mounting moving vehicle. The sensor detects motorized non-motorized traffic classifies into different modes. detected object tracked with Kalman filter method. Compared high-end high resolution, affordable cost-effective, experiment demonstrates its acceptable detection rate trajectory estimation precision....
Vehicle specific power (VSP) has been widely utilized to reveal the impact of vehicle operating conditions on estimations emissions and energy consumption that are dependent upon speed acceleration or deceleration based second-by-second operation. The analysis stop-and-go behaviors at intersections is needed for queue simulation estimation. High-resolution data obtained by driving simulator sensors can provide useful insights into behavior intersections. Hence, aggressive account a...
