The intersection is a significant part of the urban traffic network. One problems signalized intersections results an analysis that do not match field. For border crossings in 1997 Indonesia, Indonesia Highway Capacity Manual, product 1994 data processing, was used. Traffic conditions were, course, different from today. Given changes related to traffic, such as increases number vehicles, land u...

Operations-oriented traffic signal performance measures are important for identifying the need retiming to improve operations. Currently, most obtained from high-resolution controller event data, which provides information on an intersection-by-intersection basis and requires significant initial capital investment. Over 400 billion vehicle trajectory points generated each month in United States...

The objective of this study is to develop a safety propensity index (SPI) for both signalized and unsignalized intersections. Through the use of a structural equation modelling (SEM) approach safety is quantified in terms of multiple endogenous variables and related to various dimensions of exogenous variables. The singular valued SPI allows for identification of relationships between variables...

Crossroads Dr. Ir. H. Soekarno - Jalan Mulyorejo is one of the signalized intersections in bustling city Surabaya. The problem at intersection length queue and delay due to number vehicles passing through intersection. reason for conducting research assess performance traffic Data was collected by means a direct survey site. data analyzed are that pass each approach, signal time, vehicle speed ...

Human driven vehicles (HDVs) with selfish objectives cause low traffic efficiency in an un-signalized intersection. On the other hand, autonomous can overcome this inefficiency through perfect coordination. In paper, we propose intermediate solution, where use vehicular communication and a small number of to improve transportation system such intersections. our two connected (CAVs) lead multipl...

We consider a bus stop that is located a short distance upstream of a signalized intersection. A bus that dwells at this so-called " nearside stop " can impede queued cars upstream as they discharge during their green time at the intersection. Added car delays and residual queues can result. All else equal, the closer the stop's location to the intersection, the greater the potential damage to ...

Queue length is an important parameter for traffic-signal priority systems emergency vehicles. Instead of using conventional detector data, this paper investigates the feasibility queue-length estimation Google Maps color-code data via random forest (RF) and gradient-boosting machine (GBM) methods. Alternative ways specifying independent variables from are also investigated. Additionally, model...

Autonomous driving can overcome the limitations of stochastic human behavior. Therefore, implementing autonomous vehicles (AVs) could improve efficiency road networks. This study investigates impacts AV implementation on performance a signalized intersection considering mixed traffic environment comprising regular (RVs) and AVs through microscopic simulations. Accordingly, 24 scenarios with dif...
