Description
Technical field
The present invention relates to road traffic engineering field, more particularly to a kind of road-surface concrete system.
Background technology
Important component of the road-surface concrete as city parking system, refers to the both sides in boundary lines of roads width range
Or side, mark the place that several band-like road surfaces provide vehicle parking.Compared with off road parking facility, road-surface concrete has setting
It is flexibly simple, construction cost is low, takes up space less, have enough to meet the need fast, utilization rate height, the advantages that walking distance is short, while being rationally utilized
The unused resource of road, the problem of alleviating " parking difficulty " to a certain extent.But road-surface concrete is due to utilizing path space
Resource will necessarily generate Dynamic Traffic Flow on road certain interference as parking carrier, stop in especially unreasonable road
Vehicle interferes Dynamic Traffic Flow bigger, and negative effect is mainly manifested in：It occupies path resource, interference dynamic traffic, cause friendship
Logical obstruction reduces flow speeds, reduces road passage capability, increases stroke delay, induces traffic accident etc..In China, although
Suggest in road-surface concrete setting standard on the inferior grades roads such as the width road Huo Liangfu roads being set to, but more and more three width
The non-motor vehicle accommodation road of road and quadri is also used to setting parking position to service road-surface concrete.It is corresponding due to lacking
Installation warrants and the randomness of setting, unreasonable road-surface concrete make that non-vehicle flow operating status is in utter disorder, and there is an urgent need for non-
Road-surface concrete is set to provide corresponding design method on vehicle road for special use, road-surface concrete is rationally set.

What step (6) determined parks cars and non-vehicle flow number of collisions, determines non-vehicle flow service level after setting road-surface concrete,
Determining whether on-street parking spaces scale suitable according to service level class standard, if service level at D grades hereinafter, if reduce
Berth scale, return to step (6) redefine initial berth scale；If service level is at D grades or more, it is determined that road-surface concrete
Berth scale and stop mode；
(8) it according to the on-street parking spaces scale that step (7) determines and the mode of stop, selects to pacify in isolation strip aperture position
Input-output control system is filled, the system is by access display screen, electric gate, input-output control system processor and video monitor structure
Into, if service level drop to D grades it is following, in the access display screen parking position that shows that No entry, electric gate is refused
It rises；Meanwhile enabling indication wire is drawn in parking position line edge mark, enabling indication wire mark is drawn on pool bitline edges；Indication wire is ten
Word cross spider, line width 30cm, lateral length 1.5m, longitudinal length 90cm；Enabling indication wire can be with parking position line weight
It is folded；The coating of indication wire is reflecting coating, and color is white.
