Within a few years, nearly every vehicle that General Motors (GM) manufactures will have a microcontroller network known as GMLAN. A few GM vehicles already have the GMLAN network, and more vehicles with GMLAN will appear each year. GMLAN uses the Bosch-designed CAN (Controller Area Network) protocol, and it links all of a vehicle’s various processors or nodes to form an in-vehicle data network...

Classified vehicle volumes are important inputs for traffic operation, pavement design, and transportation planning. However, such data are not available from single-loop detectors, the most widely deployed type of traffic sensor in the existing roadway infrastructure. Several attempts have been made to extract classified vehicle volumes from single-loop measurements in recent years. These stud...

Automatic vehicle detectors are now common on road systems across the world. Many of these detectors are based on single inductive loops, from which data on traffic volumes (i.e. vehicle counts) and occupancy (i.e. proportion of time during which the loop is occupied) are available for 20 or 30 second observational periods. However, for the purposes of traffic management it is frequently useful...

We present an approach for turn around behavior generation and execution for an unmanned ground vehicle (UGV) operating in a rugged terrain. The generated behavior allows the vehicle to rapidly execute N-point turn maneuver in a narrow space by exploiting the vehicle’s dynamics as well as the properties of the terrain. The developed approach incorporates model-predictive planning and optimizati...

The effect of calcium on plasma atrial natriuretic factor (ANF) concentration was determined in spontaneously hypertensive rats (SHR) and their control, Wistar-Kyoto (WKY) rats. CaCl2 10.5 mg (0.095 mmol) in 0.54 ml 5% glucose or an equal volume of vehicle alone was infused intravenously for 30 minutes into conscious precannulated SHR (vehicle, n = 16; CaCl2, n = 16) and WKY rats (vehicle, n = ...

Multiparity is associated with increased risk of cardiovascular disease. We tested whether multiparity induces oxidative stress in rat vascular tissue. Coronary arteries and thoracic aorta were isolated from multiparous and age-matched virgin rats. Relaxation to ACh and sodium nitroprusside (SNP) was measured by wire myography. We also tested the effect of the superoxide dismutase mimetic MnTE2...

Objectives: To examine vehicle related mortality trends of children in Japan; and to investigate how environmental modifications such as the installation of public parks and pavements are associated with these trends. Design: Poisson regression was used for trend analysis, and multiple regression modelling was used to investigate the associations between trends in environmental modifications an...

Introduction Recently, Intelligent Transportation Systems (ITS), which among others make use of advanced sensor systems for on-line surveillance to gather detailed information on traffic conditions, have been identified as the new paradigm to address the growing mobility problems. With the exponential growth in computational capability and information technology, traffic monitoring and large-sc...

5-Hydroxytryptamine (serotonin; 5-HT)2 receptor agonists such as (+/-)-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) injected systemically or directly into frontal cortex, elicit stereotyped head movements that are mediated by 5-HT2A receptors. Chronic administration of 5-HT2A receptor antagonists can produce either a down-regulation, e.g., d-2-bromolysergic acid diethylamide (BOL) or an up...

The development of transportation technology continues to progress with various models and forms vehicles that have been produced both on a small scale large scale. use equipment can cause congestion in operating it, one way reduce this is vehicle-to-vehicle communication system conditions where there are no obstacles based the parameters used through Bit Error Rate Throuhgput.
