Estimation of the bus delay at the stopping point on the base of traffic parameters

Horbachov P., Naumov V., Kolii O.

Vol. 35, iss. 3

15--25

Contemporary methods of spatial planning of urban transport systems provide for designers enough opportunities in selecting the placement of stopping points for public transport. However in every city there exist very intense sections of the road network with a small width of the roadway. In these sections there is no opportunity to allocate special lanes for public transport. If the stop pockets on such street exist, there appear traffic conflicts when buses depart from the stopping point. Authors propose theoretical model for estimation of the bus delay at the stopping point on the base of traffic parameters. Use of the proposed model allows reducing amount of field surveys while grounding the decisions about rational variant of allocation of the bus stopping points. The paper describes some experimental results obtained with the use of the proposed model while field surveys at the most loaded streets in the central part of Kharkiv (Ukraine).

Methodology of deceleration mean value assessment of train running course record

Siroky J.

Logistyka

2009

nr 3

CD-CD

This contribution deals with the analysis of traction vehicle motion recorded by a electronical speed tachograph, and also shows the possibilities of digitising the record and its use for dynamic analysis of the traction vehicle motion. In some cases is not possible to determine collision velocity of a train (in case of extraordinary event) or stopping point, so that value could be used for calculations of deceleration mean value and theoretic braking distances calculation. For deceleration mean value assessment and braking distances calculation in this case is possible to use a procedure characterized by sequent iterative calculation of deceleration mean value.
